architecture is more code efficient while achieving throughputs up to ten times faster than con-

ventional CISC microcontrollers.

The Atmel AT90USB64/128 provides the following features: 64/128Kbytes of In-System Pro-

grammable Flash with Read-While-Write capabilities, 2K/4Kbytes EEPROM, 4K/8K bytes

SRAM, 48 general purpose I/O lines, 32 general purpose working registers, Real Time Counter

(RTC), four flexible Timer/Counters with compare modes and PWM, one USART, a byte ori-

ented 2-wire Serial Interface, a 8-channels, 10-bit ADC with optional differential input stage with

programmable gain, programmable Watchdog Timer with Internal Oscillator, an SPI serial port,

IEEE std. 1149.1 compliant JTAG test interface, also used for accessing the On-chip Debug sys-

tem and programming and six software selectable power saving modes. The Idle mode stops

the CPU while allowing the SRAM, Timer/Counters, SPI port, and interrupt system to continue

functioning. The Power-down mode saves the register contents but freezes the Oscillator, dis-

abling all other chip functions until the next interrupt or Hardware Reset. In Power-save mode,

the asynchronous timer continues to run, allowing the user to maintain a timer base while the

rest of the device is sleeping. The ADC Noise Reduction mode stops the CPU and all I/O mod-

ules except Asynchronous Timer and ADC, to minimize switching noise during ADC

conversions. In Standby mode, the Crystal/Resonator Oscillator is running while the rest of the

device is sleeping. This allows very fast start-up combined with low power consumption. In

Extended Standby mode, both the main Oscillator and the Asynchronous Timer continue to run.

The device is manufactured using the Atmel high-density nonvolatile memory technology. The

On-chip ISP Flash allows the program memory to be reprogrammed in-system through an SPI

serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot pro-

gram running on the AVR core. The boot program can use any interface to download the

application program in the application Flash memory. Software in the Boot Flash section will

continue to run while the Application Flash section is updated, providing true Read-While-Write

operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a

monolithic chip, the AT90USB64/128 is a powerful microcontroller that provides a highly flexible

and cost effective solution to many embedded control applications.

The AT90USB64/128 AVR is supported with a full suite of program and system development

tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emula-

tors, and evaluation kits.

Port B output buffers have symmetrical drive characteristics with both high sink and source

capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up

resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

Port B has better driving capabilities than the other ports.

Port B also serves the functions of various special features of the AT90USB64/128 as listed on

page 79.

2.2.6 Port C (PC7..PC0)

Port C is an 8-bit bidirectional I/O port with internal pull-up resistors (selected for each bit). The

Port C output buffers have symmetrical drive characteristics with both high sink and source

capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up

resistors are activated. The Port C pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

Port C also serves the functions of special features of the AT90USB64/128 as listed on page 82.

2.2.7 Port D (PD7..PD0)

Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The

Port D output buffers have symmetrical drive characteristics with both high sink and source

capability. As inputs, Port D pins that are externally pulled low will source current if the pull-up

resistors are activated. The Port D pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

2.2.8 Port E (PE7..PE0)

Port E is an 8-bit bidirectional I/O port with internal pull-up resistors (selected for each bit). The

Port E output buffers have symmetrical drive characteristics with both high sink and source

capability. As inputs, Port E pins that are externally pulled low will source current if the pull-up

resistors are activated. The Port E pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

Port E also serves the functions of various special features of the AT90USB64/128 as listed on

page 86.

2.2.9 Port F (PF7..PF0)

Port F serves as analog inputs to the A/D Converter.

Port F also serves as an 8-bit bidirectional I/O port, if the A/D Converter is not used. Port pins

can provide internal pull-up resistors (selected for each bit). The Port F output buffers have sym-

metrical drive characteristics with both high sink and source capability. As inputs, Port F pins

that are externally pulled low will source current if the pull-up resistors are activated. The Port F

pins are tri-stated when a reset condition becomes active, even if the clock is not running. If the

JTAG interface is enabled, the pull-up resistors on pins PF7(TDI), PF5(TMS), and PF4(TCK) will

be activated even if a reset occurs.

Port F also serves the functions of the JTAG interface.

4. About code examples

This documentation contains simple code examples that briefly show how to use various parts of

the device. Be aware that not all C compiler vendors include bit definitions in the header files

and interrupt handling in C is compiler dependent. Please confirm with the C compiler documen-

tation for more details.

These code examples assume that the part specific header file is included before compilation.

For I/O registers located in extended I/O map, "IN", "OUT", "SBIS", "SBIC", "CBI", and "SBI"

instructions must be replaced with instructions that allow access to extended I/O. Typically

"LDS" and "STS" combined with "SBRS", "SBRC", "SBR", and "CBR".

Note: 1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses

should never be written.

2. I/O registers within the address range $00 - $1F are directly bit-accessible using the SBI and CBI instructions. In these reg-

isters, the value of single bits can be checked by using the SBIS and SBIC instructions.

3. Some of the status flags are cleared by writing a logical one to them. Note that the CBI and SBI instructions will operate on

all bits in the I/O register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions

work with registers 0x00 to 0x1F only.

4. When using the I/O specific commands IN and OUT, the I/O addresses $00 - $3F must be used. When addressing I/O regis-

ters as data space using LD and ST instructions, $20 must be added to these addresses. The Atmel AT90USB64/128 is a

complex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for the

IN and OUT instructions. For the Extended I/O space from $60 - $1FF in SRAM, only the ST/STS/STD and LD/LDS/LDD

instructions can be used.

Notes: 1. A blank or any alphanumeric string.

9.1.2 AT90USB1287/6 first release

• Incorrect CPU behavior for VBUSTI and IDTI interrupts routines

• USB Eye Diagram violation in low-speed mode

• Transient perturbation in USB suspend mode generates over consumption

• VBUS Session valid threshold voltage

• USB signal rate

• VBUS residual level

• Spike on TWI pins when TWI is enabled

9. Incorrect CPU behavior for VBUSTI and IDTI interrupts routines

The CPU core may incorrectly execute the interrupt vector related to the VBUSTI and IDTI

interrupt flags.

Problem fix/workaround

Do not enable these interrupts, firmware must process these USB events by polling VBUSTI

and IDTI flags.

8. USB Eye Diagram violation in low-speed mode

The low to high transition of D- violates the USB eye diagram specification when transmitting

with low-speed signaling.

Problem fix/workaround

None.

7. Transient perturbation in USB suspend mode generates overconsumption

In device mode and when the USB is suspended, transient perturbation received on the

USB lines generates a wake up state. However the idle state following the perturbation does

not set the SUSPI bit anymore. The internal USB engine remains in suspend mode but the

USB differential receiver is still enabled and generates a typical 300µA extra-power con-

sumption. Detection of the suspend state after the transient perturbation should be

performed by software (instead of reading the SUSPI bit).

Problem fix/workaround

USB waiver allows bus powered devices to consume up to 2.5mA in suspend state.

6. VBUS session valid threshold voltage

The VSession valid threshold voltage is internally connected to VBus_Valid (4.4V approx.).

That causes the device to attach to the bus only when Vbus is greater than VBusValid

instead of V_Session Valid. Thus if VBUS is lower than 4.4V, the device is detached.

Problem fix/workaround

According to the USB power drop budget, this may require connecting the device toa root

hub or a self-powered hub.

5. UBS signal rate

The average USB signal rate may sometime be measured out of the USB specifications

(12MHz ±30kHz) with short frames. When measured on a long period, the average signal

rate value complies with the specifications. This bit rate deviation does not generates com-

munication or functional errors.

Problem fix/workaround

None.

4. VBUS residual level

In USB device and host mode, once a 5V level has been detected to the VBUS pad, a resid-

ual level (about 3V) can be measured on the VBUS pin.

Problem fix/workaround

None.

3. Spike on TWI pins when TWI is enabled

100ns negative spike occurs on SDA and SCL pins when TWI is enabled.

Problem fix/workaround

No known workaround, enable Atmel AT90USB64/128 TWI first versus the others nodes of

the TWI network.

2. High current consumption in sleep mode

If a pending interrupt cannot wake the part up from the selected mode, the current consump-

tion will increase during sleep when executing the SLEEP instruction directly after a SEI

instruction.

Problem fix/workaround

Before entering sleep, interrupts not used to wake up the part from the sleep mode should

be disabled.

1. Asynchronous timer interrupt wake up from sleep generates multiple interrupts

If the CPU core is in sleep and wakes-up from an asynchronous timer interrupt and then go

back in sleep again it may wake up multiple times.
