SJC Secure JTAG

Interface

System

Control

Peripherals

JTAG manipulation is a known hacker’s method of executing unauthorized

program code, getting control over secure applications, and running code in

privileged modes. The JTAG port provides a debug access to several

hardware blocks including the ARM processor and the system bus.

The JTAG port must be accessible during platform initial laboratory

bring-up, manufacturing tests and troubleshooting, as well as for software

debugging by authorized entities. However, in order to properly secure the

system, unauthorized JTAG usage should be strictly forbidden.

In order to prevent JTAG manipulation while allowing access for

manufacturing tests and software debugging, the i.MX53 processor

incorporates a mechanism for regulating JTAG access. SJC provides four

different JTAG security modes that can be selected through an e-fuse

configuration.

Time Clock

Security The SRTC incorporates a special system state retention register (SSRR)

that stores system parameters during system shutdown modes. This

NVCC_SRTC_POW. The NVCC_SRTC_POW can be energized

separately even if all other supply rails are shut down. This register is helpful

for storing warm boot parameters. The SSRR also stores the system

security state. In case of a security violation, the SSRR mark the event

(security violation indication).

SSI-1

SSI-2

SSI-3

I2S/SSI/AC97

Interface

Connectivity

Peripherals

The SSI is a full-duplex synchronous interface used on the i.MX53A

processor to provide connectivity with off-chip audio peripherals. The SSI

interfaces connect internally to the AUDMUX for mapping to external ports.

The SSI supports a wide variety of protocols (SSI normal, SSI network, I2S,

and AC-97), bit depths (up to 24 bits per word), and clock/frame sync

options.

Each SSI has two pairs of 8 x 24 FIFOs and hardware support for an

external DMA controller in order to minimize its impact on system

performance. The second pair of FIFOs provides hardware interleaving of

a second audio stream, which reduces CPU overhead in use cases where

two time slots are being used simultaneously.

IPTP IEEE1588

Precision Time

Protocol

Connectivity

Peripherals

The IEEE 1588-2002 (version 1) standard defines a precision time protocol

(PTP) - which is a time-transfer protocol that enables synchronization of

networks (for example, Ethernet), to a high degree of accuracy and

precision.

The IEEE1588 hardware assist is composed of the two blocks: time stamp

unit and real time clock, which provide the timestamping protocol’s

functionality, generating and reading the needed timestamps.

The hardware-assisted implementation delivers more precise clock

synchronization at significantly lower CPU load compared to purely

software implementations.

WDOG-1 Watch Dog Timer

Peripherals

The watch dog timer supports two comparison points during each counting

period. Each of the comparison points is configurable to evoke an interrupt

to the ARM core, and a second point evokes an external event on the

WDOG line.

WDOG-2

(TZ)

Watch Dog

(TrustZone)

Timer

Peripherals

The TrustZone watchdog (TZ WDOG) timer module protects against

TrustZone starvation by providing a method of escaping normal mode and

forcing a switch to the TZ mode. TZ starvation is a situation where the

normal OS prevents switching to the TZ mode. This situation should be

avoided, as it can compromise the system’s security. Once the TZ WDOG

module is activated, it must be serviced by TZ software on a periodic basis.

If servicing does not take place, the timer times out. Upon a time-out, the

TZ WDOG asserts a TZ mapped interrupt that forces switching to the TZ

mode. If it is still not served, the TZ WDOG asserts a security violation

signal to the CSU. The TZ WDOG module cannot be programmed or

deactivated by a normal mode SW.

1Voltage at the package power supply contact must be maintained between the minimum and maximum voltages. The design

must allow for supply tolerances and system voltage drops.

2The nominal values for the supplies indicate the target setpoint for a tolerance no tighter than ± 50 mV. Use of supplies with

a tighter tolerance allows reduction of the setpoint with commensurate power savings.

3A voltage transition is allowed for the required supply ramp up to the nominal value prior to achieving a clock speed increase.

Similarly, to accommodate a frequency reduction, a voltage transition is allowed for a supply ramp down to the nominal value

after the frequency is decreased.

4For BSDL mode, the minimum operating temperature is 20 oC and the maximum operating temperature is the maximum

temperature specified for the particular part grade.

5VDDA and VDDAL1 can be driven by the VDD_DIG_PLL internal regulator using external connections. When operating in this

configuration, the regulator is still operating at the default 1.2 V, as bootup start. During bootup initialization, software should

increase this regulator voltage to match VCC (1.3 V nominal) in order to reduce internal leakage current.

6By default, VDD_DIG_PLL is driven from internal on-die 1.2 V linear regulator (LDO). In this case, there is no need driving this

supply externally. LDO output to VDD_DIG_PLL should be configured by software after power-up to 1.3 V output. A bypass

capacitor of minimal value 22 μF should be connected to this pad in any case whether it is driven internally or externally. Use

of the on-chip LDO is preferred. See i.MX53 System Development User’s Guide.

7By default, the VDD_ANA_PLL is driven from internal on-die 1.8 V linear regulator (LDO). In this case there is no need driving

this supply externally. A bypass capacitor of minimal value 22 μF should be connected to this pad in any case whether it is

driven internally or externally. Use of the on-chip LDO is preferred. See i.MX53 System Development User’s Guide.

8After fuses are programmed, Freescale strongly recommends the best practice of reading the fuses to verify that they are

written correctly. In Read mode, VDD_FUSE should be floated or grounded. Tying VDD_FUSE to a positive supply (3.0 V–3.3

V) increases the possibility of inadvertently blowing fuses and is not recommended in read mode.

9If not using TVE module or other pads in this power domain for the product, the TVDAC_DHVDD and TVDAC_AHVDDRGB

can remain floating.

Electrical Characteristics

4.1.4 External Clock Sources

The i.MX53 device has four external input system clocks, a low frequency (CKIL), a high frequency

(XTAL), and two general purpose CKIH1 and CKIH2 clocks.

The CKIL is used for low-frequency functions. It supplies the clock for wake-up circuit, power-down real

time clock operation, and slow system and watch-dog counters. The clock input can be connected to either

external oscillator or a crystal using internal oscillator amplifier.

The system clock input XTAL is used to generate the main system clock. It supplies the PLLs and other

peripherals. The system clock input can be connected to either external oscillator or a crystal using internal

oscillator amplifier.

CKIH1 and CKIH2 provide additional clock source option for peripherals that require specific and

accurate frequencies.

Table 7 shows the interface frequency requirements. See Chapter 1 of i.MX53 System Development

User's Guide (MX53UG) for additional clock and oscillator information.

4.1.5 Maximal Supply Currents

Table 8 represents the maximal momentary current transients on power lines, and should be used for power

supply selection. Maximal currents higher by far than the average power consumption of typical use cases.

For typical power consumption information, refer to i.MX53 power consumption application note.

11 The analog supplies should be isolated in the application design. Use of series inductors is recommended.

12 VDD_REG is power supply input for the integrated linear regulators of VDD_ANA_PLL and VDD_DIG_PLL when they are

configured to the internal supply option. VDDR_REG still has to be tied to 2.5 V supply when VDD_ANA_PLL and

VDD_DIG_PLL are configured for external power supply mode although in this case it is not used as supply source.

4.2 Power Supply Requirements and Restrictions

The system design must comply with power-up sequence, power-down sequence and steady state

guidelines as described in this section to guarantee the reliable operation of the device. Any deviation from

these sequences may result in the following situations:

• Excessive current during power-up phase

1General Equation for estimated, maximal power consumption of an I/O power supply:

Imax = N x C x V x (0.5 x F)

Where:

N - Number of I/O pins supplies by the power line

C - Equivalent external capacitive load

V - I/O voltage

(0.5 x F) - Data change rate. Up to 0.5 of the clock rate (F).

• Prevention of the device from booting

• Irreversible damage to the i.MX53 processor (worst-case scenario)

4.2.1 Power-Up Sequence

The following observations should be considered:

•The consequent steps in power up sequence should not start before the previous step supplies have

been stabilized within 90-110% of their nominal voltage, unless stated otherwise.

•NVCC_SRTC_POW should remain powered ON continuously, to maintain internal real-time

clock status. Otherwise, it has to be powered ON together with VCC, or preceding VCC.

•The VCC should be powered ON together, or any time after NVCC_SRTC_POW.

•NVCC_CKIH should be powered ON after VCC is stable and before other I/O supplies

(NVCC_xxx) are powered ON.

•I/O Supplies (NVCC_xxx) below or equal to 2.8 V nom./3.1 V max. should not precede

NVCC_CKIH. They can start powering ON during NVCC_CKIH ramp-up, before it is

stabilized. Within this group, the supplies can be powered-up in any order.

Alternatively, the on-chip regulator VDD_ANA_PLL may be used to power NVCC_CKIH and

NVCC_RESET. In this case, the sequence defined in the “Interfacing the i.MX53 Processor

with LTC3589-1” section of the i.MX53 System Development User's Guide (MX53UG) must be

followed.

•I/O Supplies (NVCC_xxx) above 2.8 V nom./3.1 V max. should be powered ON only after

NVCC_CKIH is stable.

•In case VDD_DIG_PLL and VDD_ANA_PLL are powered ON from internal voltage regulator

(default case for i.MX53), there are no related restrictions on VDD_REG, as it is used as their

internal regulators power source.

If VDD_DIG_PLL and VDD_ANA_PLL are powered on externally, to reduce current leakage

during the power-up, it is recommended to activate the VDD_REG before or at the same time

with VDD_DIG_PLL and VDD_ANA_PLL. If this sequencing is not possible, make sure that

the 2.5 V VDD_REG supply shut-off output impedance is higher than 1 kΩ when it is inactive.

•VDD_REG supply is required to be powered ON to enable DDR operation. It must be powered

on after VCC and before NVCC_EMI_DRAM. The sequence should be:

VCC →VDD_REG →NVCC_EMI_DRAM

•VDDA and VDDAL1 can be powered ON anytime before POR_B, regardless of any other power

signal.

•VDDGP can be powered ON anytime before POR_B, regardless of any other power signal.

•VP and VPH can be powered up together, or anytime after, the VCC. VP and VPH should come

before POR.

•TVDAC_DHVDD and TVDAC_AHVDDRGB should be powered from the same regulator. This

is due to ESD diode protection circuit, that may cause current leakage if one of the supplies is

powered ON before the other.

The POR_B input must be immediately asserted at power-up and remain

asserted until after the last power rail reaches its working voltage.

4.2.2 Power-Down Sequence

Power-down sequence should follow one of the following two options:

• Option 1: Switch all supplies down simultaneously with further free discharge. A deviation of few

microseconds of actual power-down of the different power rails is acceptable.

• Option 2: Switch down supplies, in any order, keeping the following rules:

— NVCC_CKIH must be powered down at the same time or after the UHVIO I/O cell supplies

(for full supply list, refer to Table 6, Ultra High voltage I/O (UHVIO) supplies). A deviation of

few microseconds of actual power-down of the different power rails is acceptable.

— VDD_REG must be powered down at the same time or after NVCC_EMI_DRAM supply. A

deviation of few microseconds of actual power-down of the different power rails is acceptable.

— If all of the following conditions are met:

– VDD_REG is powered down to 0V (Not Hi-Z)

– VDD_DIG_PLL and VDD_ANA_PLL are provided externally,

– VDD_REG is powered down before VDD_DIG_PLL and VDD_ANA_PLL

Then the following rule should be kept: VDD_REG output impedance must be higher than 1

kW, when inactive.

4.2.3 Power Supplies Usage

• All I/O pins should not be externally driven while the I/O power supply for the pin (NVCC_xxx)

is off. This can cause internal latch-up and malfunctions due to reverse current flows. For

information about I/O power supply of each pin refer to “Power Rail” columns in pin list tables of

Section 6, “Package Information and Contact Assignments.”

• If not using SATA interface and the embedded thermal sensor, the VP and VPH should be

grounded. In particular, keeping VPH turned OFF while the VP is powered ON is not

recommended and might lead to excessive power consumption.

• When internal clock source is used for SATA temperature monitor the USB_PHY supplies and

PLL need to be active because they are providing the clock.

• If not using TVE the module, the TVDAC_DHVDD and TVDAC_AHVDDRGB can remain

floating. If only the GPIO pads in TVDAC_AHVDDRGB domain are in use, the supplies can be

set to GPIO pad voltage range (1.65 V to 3.1 V).

4.6.5 NAND Flash Controller (NFC) Parameters

This section provides the relative timing requirements among various signals of NFC at the module level,

in each operational mode.

Timing parameters in Figure 10, Figure 11, Figure 12, Figure 13, Figure 15, and Table 35 show the default

NFC mode (asymmetric mode) using two Flash clock cycles per one access of RE_B and WE_B.

Timing parameters in Figure 10, Figure 11, Figure 12, Figure 14, Figure 15, and Table 35 show symmetric

NFC mode using one Flash clock cycle per one access of RE_B and WE_B.

With reference to the timing diagrams, a high is defined as 80% of signal value and low is defined as 20%

of signal value. All parameters are given in nanoseconds. The BGA contact load used in calculations is

20 pF (except for NF16— 40 pF) and there is maximum drive strength on all contacts.

All timing parameters are a function of T, which is the period of the flash_clk clock (“enfc_clk” at system

level). This clock frequency can be controlled by the user, configuring CCM (SoC clock controller). The

clock is derived from emi_slow_clk after single divider.

Figure 34 demonstrates several examples of clock frequency settings.

NOTE

A potential limitation for minimum clock frequency may exist for some

devices. When the clock frequency is too low, the data bus capturing might

occur after the specified trhoh (RE_B high to output hold) period. Setting the

clock frequency above 25.6 MHz (that is, T = 39 ns) guaranties a proper

operation for devices having trhoh > 15 ns. It is also recommended that the

NFC_FREQ_SEL Fuse be set accordingly to initiate the boot with

33.33 MHz clock.

4Tdpdref is the time period of the reference clock after predivider. According to the specification, the maximum lock time in FOL

mode is 398 cycles of divided reference clock when DPLL starts after full reset.

5Tdck is the time period of the output clock, dpdck_2.

Electrical Characteristics

Lower frequency operation can be supported for most available devices in

the market, relying on data lines Bus-Keeper logic. This depends on device

behavior on the data bus in the time interval between data output valid to

data output high-Z state. In NAND device parameters this period is marked

between trhoh and trhz (RE_B high to output high-Z). In most devices, the

data transition from valid value to high-Z occurs without going through

other states. Setting the data bus pads to Bus-Keeper mode in the IOMUXC

registers, keeps the data bus valid internally after the specified hold time,

allowing proper capturing with slower clock.

2tDSR is calculated by the following formula:

Asymmetric mode: tDSR = tREpd + tDpd + 1/2T - Tdl3

Symmetric mode: tDSR = tREpd + tDpd - Tdl3

tREpd + tDpd = 11.2 ns (including clock skew)

where tREpd is RE propogation delay in the chip including I/O pad delay, and tDpd is Data propogation delay from I/O pad to

EXTMC including I/O pad delay.

tDSR can be used to determine tREA max parameter with the following formula: tREA = 1.5T - tDSR.

Data Setup on READ tDSR 11.2 + 0.5T - Tdl3

3Tdl is composed of 4 delay-line units each generates an equal delay with min 1.25 ns and max 1 aclk period (Taclk). Default

is 1/4 aclk period for each delay-line unit, so all 4 delay lines together generates a total of 1 aclk period. Taclk is

“emi_slow_clk” of the system, which default value is 7.5 ns (133 MHz).

4.6.6 External Interface Module (EIM)

The following subsections provide information on the EIM.

4.6.6.1 EIM Signal Cross Reference

Table 36 is a guide intended to help the user identify signals in the External Interface Module Chapter of

the Reference Manual which are identical to those mentioned in this data sheet.

4.6.6.2 EIM Interface Pads Allocation

EIM supports16-bit and 8-bit devices operating in address/data separate or multiplexed modes. In some

of the modes the EIM and the NAND FLASH have shared data bus. Table 37 provides EIM interface

pads allocation in different modes.

4NF17 is defined only in asymmetric operation mode.

NF17 max value is equivalent to max tRHZ value that can be used with NFC.

Taclk is “emi_slow_clk” of the system.

5NF18 is defined only in Symmetric operation mode.

tDHR (MIN) is calculated by the following formula: Tdl3 - (tREpd + tDpd)

where tREpd is RE propogation delay in the chip including I/O pad delay, and tDpd is Data propogation delay from I/O pad to

EXTMC including I/O pad delay.

NF18 max value is equivalent to max tRHZ value that can be used with NFC.

Taclk is “emi_slow_clk” of the system.

4.6.6.4 Examples of EIM Synchronous Accesses

Figure 18 to Figure 21 provide few examples of basic EIM accesses to external memory devices with the

timing parameters mentioned previously for specific control parameters settings.

Figure 18. Synchronous Memory Read Access, WSC=1

1t is the maximal EIM logic (axi_clk) cycle time. The maximum allowed axi_clk frequency is 133 MHz, whereas the maximum

allowed BCLK frequency is 104 MHz. As a result, if BCD = 0, axi_clk must be ≤104 MHz. If BCD = 1, then 133 MHz is

allowed for axi_clk, resulting in a BCLK of 66.5 MHz. When the clock branch to EIM is decreased to 104 MHz, other busses

are impacted which are clocked from this source. See the CCM chapter of the i.MX53 Reference Manual for a detailed clock

tree description.

2BCLK parameters are being measured from the 50% point, that is, high is defined as 50% of signal value and low is defined

as 50% as signal value.

3For signal measurements “High” is defined as 80% of signal value and “Low” is defined as 20% of signal value.

4.7.5 FEC AC Timing Parameters

This section describes the electrical information of the Fast Ethernet Controller (FEC) module. The FEC

is designed to support both 10 and 100 Mbps Ethernet/IEEE 802.3 networks. An external transceiver

interface and transceiver function are required to complete the interface to the media. The FEC supports

the 10/100 Mbps MII (18 pins in total) and the 10 Mbps (only 7-wire interface, which uses 7 of the MII

pins), for connection to an external Ethernet transceiver. For the pin list of MII and 7-wire, see the i.MX53

Reference Manual.

This section describes the AC timing specifications of the FEC. The MII signals are compatible with

transceivers operating at a voltage of 3.3 V.

4.7.5.1 MII Receive Signal Timing

The MII receive signal timing involves the FEC_RXD[3:0], FEC_RX_DV, FEC_RX_ER, and

FEC_RX_CLK signals. The receiver functions correctly up to a FEC_RX_CLK maximum frequency of

25 MHz + 1%. There is no minimum frequency requirement but the processor clock frequency must

exceed twice the FEC_RX_CLK frequency. Table 51 lists the MII receive channel signal timing

parameters and Figure 38 shows MII receive signal timings.

and/or to a display device. This support covers all aspects of these activities:

• Connectivity to relevant devices—cameras, displays, graphics accelerators, and TV encoders.

• Related image processing and manipulation: sensor image signal processing, display processing,

image conversions, and other related functions.

• Synchronization and control capabilities, such as avoidance of tearing artifacts.

4.7.8.2 Sensor Interface Timings

There are three camera timing modes supported by the IPU.

4.7.8.2.1 BT.656 and BT.1120 Video Mode

Smart camera sensors, which include imaging processing, usually support video mode transfer. They use

an embedded timing syntax to replace the SENSB_VSYNC and SENSB_HSYNC signals. The timing

syntax is defined by the BT.656/BT.1120 standards.

This operation mode follows the recommendations of ITU BT.656/ ITU BT.1120 specifications. The only

control signal used is SENSB_PIX_CLK. Start-of-frame and active-line signals are embedded in the data

stream. An active line starts with a SAV code and ends with a EAV code. In some cases, digital blanking

is inserted in between EAV and SAV code. The CSI decodes and filters out the timing-coding from the data

stream, thus recovering SENSB_VSYNC and SENSB_HSYNC signals for internal use. On BT.656 one

component per cycle is received over the SENSB_DATA bus. On BT.1120 two components per cycle are

received over the SENSB_DATA bus.

4.7.8.2.2 Gated Clock Mode

The SENSB_VSYNC, SENSB_HSYNC, and SENSB_PIX_CLK signals are used in this mode. See

Figure 44.

Figure 44. Gated Clock Mode Timing Diagram

A frame starts with a rising edge on SENSB_VSYNC (all the timings correspond to straight polarity of the

corresponding signals). Then SENSB_HSYNC goes to high and hold for the entire line. Pixel clock is valid

as long as SENSB_HSYNC is high. Data is latched at the rising edge of the valid pixel clocks.

2The MSB bits are duplicated on LSB bits implementing color extension

3The two MSB bits are duplicated on LSB bits implementing color extension

4RGB 16 bits— Supported in two ways: (1) As a “generic data” input, with no on-the-fly processing; (2) With on-the-fly

processing, but only under some restrictions on the control protocol.

5YCbCr 16 bits— Supported as a “generic-data” input, with no on-the-fly processing.

6YCbCr 16 bits— Supported as a sub-case of the YCbCr, 20 bits, under the same conditions (BT.1120 protocol).

7YCbCr, 20 bits— Supported only within the BT.1120 protocol (syncs embedded within the data stream).

Electrical Characteristics

SENSB_HSYNC goes to low at the end of line. Pixel clocks then become invalid and the CSI stops

receiving data from the stream. For next line the SENSB_HSYNC timing repeats. For next frame the

SENSB_VSYNC timing repeats.

4.7.8.2.3 Non-Gated Clock Mode

The timing is the same as the gated-clock mode (described in Section 4.7.8.2.2, “Gated Clock Mode,”)

except for the SENSB_HSYNC signal, which is not used (see Figure 45). All incoming pixel clocks are

valid and cause data to be latched into the input FIFO. The SENSB_PIX_CLK signal is inactive (states

low) until valid data is going to be transmitted over the bus.

Figure 45. Non-Gated Clock Mode Timing Diagram

The timing described in Figure 45 is that of a typical sensor. Some other sensors may have a slightly

different timing. The CSI can be programmed to support rising/falling-edge triggered SENSB_VSYNC;

active-high/low SENSB_HSYNC; and rising/falling-edge triggered SENSB_PIX_CLK.

table for details.

4.7.8.5 IPU Display Interface Timing

The IPU Display Interface supports two kinds of display accesses: synchronous and asynchronous. There

are two groups of external interface pins to provide synchronous and asynchronous controls accordantly.

4.7.8.5.1 Synchronous Controls

The synchronous control changes its value as a function of a system or of an external clock. This control

has a permanent period and a permanent wave form.

There are special physical outputs to provide synchronous controls:

• The ipp_disp_clk is a dedicated base synchronous signal that is used to generate a base display

(component, pixel) clock for a display.

• The ipp_pin_1– ipp_pin_7 are general purpose synchronous pins, that can be used to provide

HSYNC, VSYNC, DRDY or any else independent signal to a display.

The IPU has a system of internal binding counters for internal events (such as HSYNC/VSYCN and so on)

calculation. The internal event (local start point) is synchronized with internal DI_CLK. A suitable control

starts from the local start point with predefined UP and DOWN values to calculate control’s changing

points with half DI_CLK resolution. A full description of the counters system can be found in the IPU

chapter of the i.MX53 Reference Manual.

4.7.8.5.2 Asynchronous Controls

The asynchronous control is a data-oriented signal that changes its value with an output data according to

additional internal flags coming with the data.

There are special physical outputs to provide asynchronous controls, as follows:

• The ipp_d0_cs and ipp_d1_cs pins are dedicated to provide chip select signals to two displays.

• The ipp_pin_11– ipp_pin_17 are general purpose asynchronous pins, that can be used to provide

WR. RD, RS or any other data oriented signal to display.

NOTE

The IPU has independent signal generators for asynchronous signals

toggling. When a DI decides to put a new asynchronous data in the bus, a

new internal start (local start point) is generated. The signals generators

calculate predefined UP and DOWN values to change pins states with half

DI_CLK resolution.

4.7.8.6 Synchronous Interfaces to Standard Active Matrix TFT LCD Panels

4.7.8.6.1 IPU Display Operating Signals

The IPU uses four control signals and data to operate a standard synchronous interface:

• IPP_DISP_CLK—Clock to display

• HSYNC—Horizontal synchronization

• VSYNC—Vertical synchronization

• DRDY—Active data

All synchronous display controls are generated on the base of an internally generated “local start point”.

The synchronous display controls can be placed on time axis with DI’s offset, up and down parameters.

The display access can be whole number of DI clock (Tdiclk) only. The IPP_DATA can not be moved

relative to the local start point. The data bus of the synchronous interface is output direction only.

4.7.8.6.2 LCD Interface Functional Description

Figure 47 depicts the LCD interface timing for a generic active matrix color TFT panel. In this figure

signals are shown with negative polarity. The sequence of events for active matrix interface timing is:

• DI_CLK internal DI clock, used for calculation of other controls.

• IPP_DISP_CLK latches data into the panel on its negative edge (when positive polarity is selected).

In active mode, IPP_DISP_CLK runs continuously.

• HSYNC causes the panel to start a new line. (Usually IPP_PIN_2 is used as HSYNC.)

• VSYNC causes the panel to start a new frame. It always encompasses at least one HSYNC pulse.

(Usually IPP_PIN_3 is used as VSYNC.)

• DRDY acts like an output enable signal to the CRT display. This output enables the data to be

shifted onto the display. When disabled, the data is invalid and the trace is off.

(DRDY can be used either synchronous or asynchronous generic purpose pin as well.)

4.7.8.7 Interface to a TV Encoder (TVDAC)

The interface has an 8-bit data bus, transferring a single 8-bit value (Y/U/V) in each cycle. The timing of

the interface is described in Figure 51.

NOTE

• The frequency of the clock DISP_CLK is 27 MHz (within 10%)

• The HSYNC, VSYNC signals are active low.

• The DRDY signal is shown as active high.

• The transition to the next row is marked by the negative edge of the

HSYNC signal. It remains low for a single clock cycle.

• The transition to the next field/frame is marked by the negative edge of

the VSYNC signal. It remains low for at least one clock cycles.

— At a transition to an odd field (of the next frame), the negative edges

of VSYNC and HSYNC coincide.

— At a transition is to an even field (of the same frame), they do not

coincide.

• The active intervals—during which data is transferred—are marked by

the HSYNC signal being high.

4.7.8.8 Asynchronous Interfaces

The following sections describes the types of asynchronous interfaces.

4.7.8.8.1 Standard Parallel Interfaces

The IPU has four signal generator machines for asynchronous signal. Each machine generates IPU’s

internal control levels (0 or 1) by UP and DOWN that are defined in registers. Each asynchronous pin has

a dynamic connection with one of the signal generators. This connection is redefined again with a new

display access (pixel/component). The IPU can generate control signals according to system 80/68

requirements. The burst length is received as a result from predefined behavior of the internal signal

generator machines.

The access to a display is realized by the following:

• CS (IPP_CS) chip select

• WR (IPP_PIN_11) write strobe

• RD (IPP_PIN_12) read strobe

• RS (IPP_PIN_13) Register select (A0)

Both system 80 and system 68k interfaces are supported for all described modes as depicted in Figure 52,

Figure 53, Figure 54, and Figure 55. The timing images correspond to active-low IPP_CS, WR and RD

signals.

Each asynchronous access is defined by an access size parameter. This parameter can be different between

different kinds of accesses. This parameter defines a length of windows, when suitable controls of the

current access are valid. A pause between two different display accesses can be guaranteed by programing

suitable access sizes. There are no minimal/maximal hold/setup times hard defined by DI. Each control

signal can be switched at any time during access size.

4.7.12 PATA Timing Parameters

This section describes the timing parameters of the Parallel ATA module which are compliant with

ATA/ATAPI-6 specification.

Parallel ATA module can work on PIO/Multi-Word DMA/Ultra DMA transfer modes. Each transfer mode

has different data transfer rate, Ultra DMA mode 4 data transfer rate is up to 100MB/s. Parallel ATA

module interface consist of a total of 29 pins. Some pins act on different function in different transfer

mode. There are different requirements of timing relationships among the function pins conform with

ATA/ATAPI-6 specification and these requirements are configurable by the ATA module registers.

Table 69 and Figure 63 define the AC characteristics of all the PATA interface signals in all data transfer

modes.

Figure 63. PATA Interface Signals Timing Diagram

The user must use level shifters for 5.0 V compatibility on the ATA interface. The i.MX53 PATA interface

is 3.3 V compatible.

The use of bus buffers introduces delay on the bus and skew between signal lines. These factors make it

difficult to operate the bus at the highest speed (UDMA-5) when bus buffers are used. If fast UDMA mode

operation is needed, this may not be compatible with bus buffers.

Another area of attention is the slew rate limit imposed by the ATA specification on the ATA bus.

According to this limit, any signal driven on the bus should have a slew rate between 0.4 and 1.2 V/ns with

a 40 pF load. Not many vendors of bus buffers specify slew rate of the outgoing signals.

When bus buffers are used, the ata_data bus buffer is special. This is a bidirectional bus buffer, so a

direction control signal is needed. This direction control signal is ata_buffer_en. When its high, the bus

should drive from host to device. When its low, the bus should drive from device to host. Steering of the

signal is such that contention on the host and device tri-state busses is always avoided.

4.7.13 SATA PHY Parameters

This section describes SATA PHY electrical specifications.

4.7.13.1 Reference Clock Electrical and Jitter Specifications

The refclk signal is differential and supports frequencies of 25 MHz or 50-156.25 MHz (100 MHz and

125 MHz are common frequencies). The frequency is pin-selectable (for more information about the

signal, see “Per-Transceiver Control and Status Signals” in the SATA PHY chapter in the Reference

Manual).

Table 76 provides the SATA PHY reference clock specifications.

4.7.13.1.1 Reference Clock Jitter Measurement

The total phase jitter on the reference clock is specified at 3 ps RMS. There are numerous ways to measure

the reference clock jitter, one of which is as follows.

Using a high-speed sampling scope (20 GSamples/s), 1 million samples of the differential reference clock

are taken, and the zero-crossing times of each rising edge are calculated. From the zero-crossing data, an

average reference clock period is calculated. This average reference clock period is subtracted from each

sequential, instantaneous period to find the difference between each reference clock rising edge and the

ideal placement to produce the phase jitter sequence. The power spectral density (PSD) of the phase jitter

is calculated and integrated after being weighted with the transfer function shown in Figure 74. The square

root of the resultant integral is the RMS total phase jitter.

Figure 74. Weighting Function for RMS Phase Jitter Calculation

4.7.13.2 Transmitter and Receiver Characteristics

The SATA PHY meets or exceeds the electrical compliance requirements defined in the SATA

specification. The following subsections provide values obtained from a combination of simulations and

silicon characterization.

NOTE

The tables in the following sections indicate any exceptions to the SATA

specification or aspects of the SATA PHY that exceed the standard, as well

as provide information about parameters not defined in the standard.

4.7.13.2.2 SATA PHY Receiver Characteristics

Table 78 provides specifications for SATA PHY receiver characteristics.

4.7.13.3 SATA_REXT Reference Resistor Connection

The impedance calibration process requires connection of reference resistor 191 Ω.1% precision resistor

on SATA_REXT pad to ground.

Resistor calibration consists of learning which state of the internal Resistor Calibration register causes an

internal, digitally trimmed calibration resistor to best match the impedance applied to the SATA_REXT

pin. The calibration register value is then supplied to all Tx and Rx termination resistors.

During the calibration process (for a few tens of microseconds), up to 0.3 mW can be dissipated in the

external SATA_REXT resistor. At other times, no power is dissipated by the SATA_REXT resistor.

4.7.13.4 SATA Connectivity When Not in Use

NOTE

The Temperature Sensor is part of the SATA module. If SATA IP is disabled,

the Temperature Sensor will not work as well. Temperature Sensor

functionality is important in supporting high performance applications

without overheating the device (at high ambient temp).

When both SATA and thermal sensor are not required, connect VP and VPH supplies to ground. The rest

of the ports, both inputs and outputs (SATA_REFCLKM, SATA_REFCLKP, SATA_REXT, SATA_RXM,

SATA_RXP, SATA_TXM) can be left floating. It is not recommended to turn off the VPH while the VP is

active.

When SATA is not in use but thermal sensor is still required, both VP and VPH supplies must be powered

on according to their nominal voltage levels. The reference clock input frequency must fall within the

specified range of 25 MHz to 156.25 MHz. SATA_REXT does not need to be connected, as the

termination impedance is not of consequence.

5.1 Boot Mode Configuration Pins

Table 108 provides boot options, functionality, fuse values, and associated pins. Several input pins are also

sampled at reset and can be used to override fuse values, depending on the value of BT_FUSE_SEL fuse.

The boot option pins are in effect when BT_FUSE_SEL fuse is ‘0’ (cleared, which is the case for an

unblown fuse). For detailed boot mode options configured by the boot mode pins, please refer to the

5.3 Power Setup During Boot

By default, VDD_DIG_PLL is driven from internal on-die 1.2 V linear regulator (LDO). In order to

achieve the standard operating mode (see VDD_DIG_PLL on Table 6), LDO output to VDD_DIG_PLL

should be configured by software by boot code after power-up to 1.3 V output. This is done by

programming the PLL1P2_VREG bits.
