Device Configuration
The EPC1, EPC2, and EPC1441 devices store configuration data in its erasable
programmable read-only memory (EPROM) array and serially clock data out using
an internal oscillator. The
OE
,
nCS
, and
DCLK
pins supply the control signals for the
address counter and the
DATA
output tri-state buffer. The configuration device sends a
serial bitstream of configuration data to its
DATA
pin, which is routed to the
DATA0
input of the FPGA.
The control signals for configuration devices,
OE
,
nCS
, and
DCLK
, interface directly with
the FPGA control signals,
nSTATUS
,
CONF
_
DONE
, and
DCLK
. All Altera FPGAs can be
configured by a configuration device without requiring an external intelligent
controller.
1An EPC2 device cannot configure FLEX 8000 or FLEX 6000 devices. For configuration
devices that support FLEX 8000 or FLEX 6000 devices, refer to Table 2.
Figure 2 shows the basic configuration interface connections between the
configuration device and the Altera FPGA.
The EPC2 device allows you to begin configuration of the FPGA using an additional
pin,
nINIT
_
CONF
. The
nINIT
_
CONF
pin of the EPC2 device can be connected to the
nCONFIG
pin of the FPGA, which allows the
INIT
_
CONF
JTAG instruction to begin
FPGA configuration. The
INIT
_
CONF
JTAG instruction causes the EPC2 device to drive
the
nINIT
_
CONF
pin low, which in turn pulls the
nCONFIG
pin low. Pulling the
nCONFIG
pin low on the FPGA will reset the device. When the JTAG state machine exits this
state, the
nINIT
_
CONF
pin is released and pulled high by an internal 1-k resistor,
which in turn pulls the
nCONFIG
pin high to begin configuration. If you do not use the
nINIT
_
CONF
pin, disconnect the
nINIT
_
CONF
pin, and pull the
nCONFIG
pin of the FPGA
to VCC either directly or through a resistor.

Notes to Figure 2:
(1) For more information about configuration interface connections, refer to the configuration chapter in the appropriate device handbook.
(2) The n
INIT
_
CONF
pin which is available on EPC2 devices has an internal pull-up resistor that is always active. This means an external pull-up
resistor is not required on the n
INIT
_
CONF
/n
CONFIG
line. The n
INIT
_
CONF
pin does not need to be connected if its functionality is not used.
If the n
INIT
_
CONF
pin is not used or unavailable, n
CONFIG
must be pulled to VCC
either directly or through a resistor.
(3) EPC2 devices have internal programmable pull-up resistors on
OE
and n
CS
pins. If internal pull-up resistors are used, do not use external pull-up
resistors on these pins. The internal pull-up resistors are set by default in the Quartus II software. To turn off the internal pull-up resistors, check
the Disable nCS and OE pull-ups on configuration device option when you generate programming files.

The EPC2 device’s
OE
and
nCS
pins have internal programmable pull-up resistors. If
you use internal pull-up resistors, do not use external pull-up resistors on these pins.
The internal pull-up resistors are set by default in the Quartus II software. To turn off
the internal pull-up resistors, check the Disable nCS and OE pull-ups on
configuration device option when you generate programming files.
The configuration device’s
OE
and
nCS
pins control the tri-state buffer on its
DATA
output pin and enable the address counter and oscillator. When the
OE
pin is driven
low, the configuration device resets the address counter and tri-states its
DATA
pin. The
nCS
pin controls the
DATA
output of the configuration device. If the
nCS
pin is held high
after the
OE
reset pulse, the counter is disabled and the
DATA
output pin is tri-stated. If
the
nCS
pin is driven low after the
OE
reset pulse, the counter and
DATA
output pin are
enabled. When
OE
is driven low again, the address counter is reset and the
DATA
output pin is tri-stated, regardless of the state of the
nCS
pin.
If the FPGA’s configuration data exceeds the capacity of a single EPC1 or EPC2
configuration device, you can cascade multiple EPC1 or EPC2 devices together. If
multiple EPC1 or EPC2 devices are required, the
nCASC
and
nCS
pins provide
handshaking between the configuration devices.
1EPC1441 and EPC1064/EPC1064V devices cannot be cascaded.
When configuring ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone, Cyclone II,
FLEX 10K, Mercury, Stratix, Stratix GX, Stratix II, and Stratix II GX devices with
cascaded EPC1 or EPC2 devices, the position of the EPC1 or EPC2 device in the chain
determines its mode of operation. The first configuration device in the chain is the
master, while subsequent configuration devices are slaves. The
nINIT
_
CONF
pin of the
EPC2 master device can be connected to the
nCONFIG
pin of the FPGAs, which allows
the
INIT
_
CONF
JTAG instruction to begin FPGA configuration. The
nCS
pin of the
master configuration device is connected to the
CONF
_
DONE
pin of the FPGAs, while its
nCASC
pin is connected to the
nCS
pin of the next slave configuration device in the
chain. Additional EPC1 or EPC2 devices can be chained together by connecting the
nCASC
pin to the
nCS
pin of the next EPC1 or EPC2 slave device in the chain. The last
device’s
nCS
input comes from the previous device, while its
nCASC
pin is left floating.
All other configuration pins,
DCLK
,
DATA
, and
OE
, are connected to every device in the
chain.
fFor more information about configuration interface connections, including pull-up
resistor values, supply voltages, and
MSEL
pin setting, refer to the configuration
chapter in the appropriate device handbook.
Page 8 Device Configuration
Configuration Devices for SRAM-Based LUT Devices January 2012 Altera Corporation
Figure 3 shows the basic configuration interface connections between a configuration
device chain and the Altera FPGA.
When the first device in a configuration device chain is powered-up or reset, its
nCS
pin is driven low because it is connected to the
CONF
_
DONE
pin of the FPGA. Because
both
OE
and
nCS
pins are low, the first device in the chain recognizes it as the master
device and controls configuration. Since the slave devices’
nCS
pin is fed by the
previous devices’
nCASC
pin, its
nCS
pin is high after power-up and reset. In the slave
configuration devices, the
DATA
output is tri-stated and
DCLK
is an input. During
configuration, the master device supplies the clock through
DCLK
to the FPGA and to
any slave configuration devices. The EPC1 or EPC2 master device also provides the
first stream of data to the FPGA during multi-device configuration. After the EPC1 or
EPC2 master device finishes sending configuration data, it tri-states its
DATA
pin to
avoid contention with other configuration devices. The EPC1 or EPC2 master device
also drives its
nCASC
pin low, which pulls the
nCS
pin of the next device low. This
action signals the EPC1 or EPC2 slave device to start sending configuration data to the
FPGAs.
The EPC1 or EPC2 master device clocks all slave configuration devices until
configuration is complete. When all configuration data is transferred and the
nCS
pin
on the EPC1 or EPC2 master device is driven high by the FPGA’s
CONF
_
DONE
pin, the
EPC1 or EPC2 master device then goes into zero-power (idle) state. The EPC2 master
device drives
DATA
high and
DCLK
low, while the EPC1 and EPC1441 device tri-state
DATA
and drive
DCLK
low.
If the
nCS
pin on the EPC1 or EPC2 master device is driven high before all
configuration data is transferred, the EPC1 or EPC2 master device drives its
OE
signal
low, which in turn drives the FPGA’s
nSTATUS
pin low, indicating a configuration
error. Additionally, if the configuration device generates its data and detects that the
CONF
_
DONE
pin has not gone high, it recognizes that the FPGA has not configured
successfully. EPC1 and EPC2 devices wait for 16
DCLK
cycles after the last

configuration bit was sent for the

pin to reach a high state. In this case, the
configuration device pulls its
OE
pin low, which in turn drives the target device’s
nSTATUS
pin low. Configuration automatically restarts if the Auto-restart
configuration on error option is turned on in the Quartus II software from the
General tab of the Device & Pin Options dialog box or the MAX+PLUS II software’s
Global Project Device Options dialog box (Assign menu).
fFor more information about FPGA configuration and configuration interface
connections between configuration devices and Altera FPGAs, refer to the
configuration chapter in the appropriate device handbook.
Power and Operation
This section describes power-on reset (POR) delay, error detection, and 3.3-V and
5.0-V operation of Altera configuration devices.
Power-On Reset
During initial power-up, a POR delay occurs to permit voltage levels to stabilize.
When configuring an FPGA with one EPC1, EPC2, or EPC1441 device, the POR delay
occurs inside the configuration device and the POR delay is a maximum of 200 ms.
When configuring a FLEX 8000 device with one EPC1213, EPC1064, or EPC1064V
device, the POR delay occurs inside the FLEX 8000 device and the POR delay is
typically 100 ms, with a maximum of 200 ms.
During POR, the configuration device drives its
OE
pin low. This low signal delays
configuration because the
OE
pin is connected to the target FPGA’s
nSTATUS
pin. When
the configuration device completes POR, it releases its open-drain
OE
pin, which is
then pulled high by a pull-up resistor.
1You should power up the FPGA before the configuration device exits POR to avoid
the master configuration device from entering slave mode.
If the FPGA is not powered up before the configuration device exits POR, the
CONF
_
DONE
/
nCS
line is high because of the pull-up resistor. When the configuration
device exits POR and releases
OE
, it sees
nCS
high, which signals the configuration
device to enter slave mode. Therefore, configuration will not begin because the
DATA
output is tri-stated and
DCLK
is an input pin in slave mode.
Error Detection Circuitry
The EPC1, EPC2, and EPC1441 configuration devices have built-in error detection
circuitry for configuring ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone,
Cyclone II, FLEX 10K, FLEX 6000, Mercury, Stratix, Stratix GX, Stratix II, or
Stratix II GX devices.
Built-in error detection circuitry uses the
nCS
pin of the configuration device, which
monitors the
CONF
_
DONE
pin on the FPGA. If the
nCS
pin on the EPC1 or EPC2 master
device is driven high before all configuration data is transferred, the EPC1 or EPC2
master device drives its
OE
signal low, which in turn drives the FPGA’s
nSTATUS
pin
low, indicating a configuration error. Additionally, if the configuration device
generates its data and detects that the
CONF
_
DONE
pin has not gone high, it recognizes
Page 10 Power and Operation
Configuration Devices for SRAM-Based LUT Devices January 2012 Altera Corporation
that the FPGA has not configured successfully. EPC1 and EPC2 devices wait for
16
DCLK
cycles after the last configuration bit was sent for the
CONF
_
DONE
pin to reach a
high state. In this case, the configuration device pulls its
OE
pin low, which in turn
drives the target device’s
nSTATUS
pin low. Configuration automatically restarts if the
Auto-restart configuration on error option is turned on in the Quartus II software
from the General tab of the Device & Pin Options dialog box or the MAX+PLUS II
software’s Global Project Device Options dialog box (Assign menu).
In addition, if the FPGA detects a cyclic redundancy check (CRC) error in the received
data, it will flag the error by driving the
nSTATUS
signal low. This low signal on
nSTATUS
drives the
OE
pin of the configuration device low, which resets the
configuration device. CRC checking is performed when configuring all Altera FPGAs.
3.3-V or 5.0-V Operation
Power the EPC1, EPC2, and EPC 1441 configuration device at 3.3 V or 5.0 V. For each
configuration device, an option must be set for the 3.3-V or 5.0-V operation.
For EPC1 and EPC1441 configuration devices, 3.3-V or 5.0-V operation is controlled
by a programming bit in the .pof. The Low-Voltage mode option in the Options tab of
the Configuration Device Options dialog box in the Quartus II software or the Use
Low-Voltage Configuration EPROM option in the Global Project Device Options
dialog box (Assign menu) in the MAX+PLUS II software sets this parameter. For
example, EPC1 devices are programmed automatically to operate in 3.3-V mode when
configuring FLEX 10KA devices, which have a VCC voltage of 3.3 V. In this example,
the EPC1 device’s
VCC
pin is connected to a 3.3-V power supply.
For EPC2 devices, this option is set externally by the
VCCSEL
pin. In addition, the EPC2
device has an externally controlled option, set by the
VPPSEL
pin, to adjust the
programming voltage to 5.0 V or 3.3 V. The functions of the
VCCSEL
and
VPPSEL
pins
are described below. These pins are only available in the EPC2 devices.
■
VCCSEL
pin—For EPC2 configuration devices, 5.0-V or 3.3-V operation is controlled
by the
VCCSEL
option pin. The device functions in 5.0-V mode when
VCCSEL
is
connected to GND and 3.3-V mode when
VCCSEL
is connected to VCC.
■
VPPSEL
pin—The VPP programming power pin of the EPC2 device is normally tied
to VCC. For EPC2 devices operating at 3.3 V, it is possible to improve ISP time by
setting VPP to 5.0 V. For all other configuration devices, VPP must be tied to VCC.
The
VPPSEL
pin of the EPC2 device must be set in accordance with the
VPP
pin of
the EPC2 device. If the
VPP
pin is supplied by a 5.0-V power supply,
VPPSEL
must
be connected to GND and if the
VPP
pin is supplied by a 3.3-V power supply,
VPPSEL
must be connected to VCC.
Power and Operation Page 11
Configuration Devices for SRAM-Based LUT DevicesJanuary 2012 Altera Corporation
Tabl e 3 lists the relationship between the VCC and VPP voltage levels and the required
logic level for
VCCSEL
and
VPPSEL
pins. A high logic level means the pin should be
connected to VCC, while a low logic level means the pin should be connected to GND.
At a 3.3-V operation, all EPC2 inputs are 5.0-V tolerant, except for
DATA
,
DCLK
, and
nCASC
pins. The
DATA
and
DCLK
pins are used only to interface between the EPC2
device and the FPGA it is configuring. Tab l e 4 lists the voltage tolerences of all EPC2
device pins.
If one EPC1, EPC2, or EPC1441 configuration device is powered at 3.3 V, the
nSTATUS
and
CONF
_
DONE
pull-up resistors must be connected to 3.3 V. If these configuration
devices are powered at 5.0 V, the

pull-up resistors can be
connected to either 3.3 V or 5.0 V.

Configuration Devices for SRAM-Based LUT Devices January 2012 Altera Corporation
Programming and Configuration File Support
The Quartus II and MAX+PLUS II softwares provide programming support for Altera
configuration devices. During compilation, the Quartus II and MAX+PLUS II
softwares automatically generates a .pof, which is used to program the configuration
devices. In a multi-device configuration, the software combines the programming
files for multiple ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone, Cyclone II,
FLEX 10K, Mercury, Stratix, Stratix GX, Stratix II, and Stratix II GX devices into one or
more configuration devices. The software allows you to select the appropriate
configuration device to store the data for each FPGA.
All Altera configuration devices are programmable using Altera programming
hardware in conjunction with the Quartus II or MAX+PLUS II software. In addition,
many third-party programmers offer programming hardware that supports Altera
configuration devices.
1An EPC2 device can be programmed with a .pof generated for an EPC1 or EPC1441
device. An EPC1 device can be programmed with a .pof generated for an EPC1441
device.
EPC2 configuration devices can be programmed in-system through its
industry-standard four-pin JTAG interface. ISP capability in the EPC2 devices provide
ease in prototyping and FPGA functionality. When programming multiple EPC2
devices in a JTAG chain, the Quartus II and MAX+PLUS II softwares and other
programming methods employ concurrent programming to simultaneously program
multiple devices and reduce programming time. EPC2 devices can be programmed
and erased up to 100 times.
After programming an EPC2 device in-system, FPGA configuration is initiated by the
INIT
_
CONF
JTAG instruction of the EPC2 device. For more information, refer to
Tabl e 6.
fFor more information about programming and configuration support, refer to the
following documents:

■USB-Blaster Download Cable User Guide
■MasterBlaster Serial/USB Communications Cable User Guide
■ByteBlaster II Download Cable User Guide
■ByteBlasterMV Download Cable User Guide
■BitBlaster Serial Download Cable Data Sheet
You can also program the configuration devices using the Quartus II or MAX+PLUS II
software with the APU or the appropriate configuration device programming adapter.
Programming and Configuration File Support Page 13
Configuration Devices for SRAM-Based LUT DevicesJanuary 2012 Altera Corporation
Tabl e 5 lists the programming adapter to use with each configuration device.
To program Altera configuration devices using the Quartus II software and the APU,
follow these steps:
1. Choose the Quartus II Programmer (Tools menu).
2. Load the appropriate .pof by clicking Add. The Device column displays the
device for the current programming file.
3. Insert a blank configuration device into the programming adapter’s socket.
4. Turn on the Program/Configure. You can also turn on Verify to verify the contents
of a programmed device against the programming data loaded from a
programming file.
5. Click Start.
6. After successful programming, you can place the configuration device on the PCB
to configure the FPGA device.
To program Altera configuration devices using the MAX+PLUS II software and the
APU, follow these steps:
1. Open the MAX+PLUS II Programmer.
2. Load the appropriate .pof using the Select Programming File dialog box (File
menu). By default, the Programmer loads the current project’s .pof. The Device
field displays the device for the current programming file.
3. Insert a blank configuration device into the programming adapter’s socket.
4. Click Program.
5. After successful programming, you can place the configuration device on the PCB
to configure the FPGA device.
If you are cascading EPC1 or EPC2 devices, you must generate multiple .pof. The first
device .pof have the same name as the project, while the second device .pof have the
same name as the first, but with a “_1” extension (e.g., top_1.pof).

Configuration Devices for SRAM-Based LUT Devices January 2012 Altera Corporation
IEEE Std. 1149.1 (JTAG) Boundary-Scan Testing
The EPC2 device provides JTAG BST circuitry that complies with the IEEE Std.
1149.1-1990 specification. You can perform JTAG BST before or after configuration, but
not during configuration. Table 6 lists the JTAG instructions supported by the EPC2
device.
fFor more information, refer to AN39: IEEE 1149.1 JTAG Boundary-Scan Testing in Altera
Devices.
Table 6. EPC2 Device JTAG Instructions
JTAG Instruction OPCODE Description
SAMPLE/PRELOAD 00 0101 0101
Allows a snapshot of a signal at the device pins to be captured and
examined during normal device operation and permits an initial data
pattern output at the device pins.
EXTEST 00 0000 0000
Allows the external circuitry and board-level interconnections to be
tested by forcing a test pattern at the output pins and capturing
results at the input pins.
BYPASS 11 1111 1111
Places the 1-bit bypass register between the
TDI
and
TDO
pins,
which allows the BST data to pass synchronously through a selected
device to adjacent devices during normal device operation.
IDCODE 00 0101 1001
Selects the device
IDCODE
register and places it between the
TDI
and
TDO
pins, allowing the device
IDCODE
to be serially shifted out of
the
TDO
pin. The device
IDCODE
for the EPC2 configuration device is
shown below:
0000 0001000000000010 00001101110 1
USERCODE 00 0111 1001
Selects the USERCODE register and places it between the
TDI
and
TDO
pins, allowing the USERCODE to be serially shifted out of the
TDO
pin. The 32-bit USERCODE is a programmable user-defined
pattern.
INIT_CONF 00 0110 0001
Initiates the FPGA re-configuration process by pulsing the
n
INIT_CONF
pin low, which is connected to the FPGAs n
CONFIG
pins. After this instruction is updated, the n
INIT_CONF
pin is pulsed
low when the JTAG state machine enters the Run-Test/Idle state. The
n
INIT_CONF
pin is then released and
nCONFIG
is pulled high by the
resistor after the JTAG state machine goes out of Run-Test/Idle state.
The FPGA configuration starts after the n
CONFIG
pin goes high. As a
result, the FPGA is configured with the new configuration data stored
in the configuration device. You can add this function to your
programming file (.pof, .jam, .jbc) in the Quartus II software by
enabling the Initiate configuration after programming option in the
Programmer options window (Options menu). This instruction is
also used by the MAX+PLUS II software, .jam files, and .jbc files.
ISP Instructions —
These instructions are used when programming an EPC2 device
using JTAG ports with a USB-Blaster, MasterBlaster, ByteBlaster II,
EthernetBlaster, or ByteBlasterMV download cable, or using a .jam,
.jbc, or .svf file using an embedded processor.

20-Pin
PLCC
32-Pin
TQFP (2)
DATA
1231Output
Serial data output. The
DATA
pin connects to the
DATA0
pin
of the FPGA.
DATA
is latched into the FPGA on the rising
edge of
DCLK
.
The
DATA
pin is tri-stated before configuration and when
the n
CS
pin is high. After configuration, the EPC2 device
drives
DATA
high, while the EPC1 and EPC1441 device
tri-state
DATA
.
DCLK
2 4 2 Bidirectional
Clock output when configuring with a single configuration
device or when the configuration device is the first
(master) device in a chain. Clock input for the next (slave)
configuration devices in a chain. The
DCLK
pin connects to
the
DCLK
pin of the FPGA.
Rising edges on
DCLK
increment the internal address
counter and present the next bit of data on the
DATA
pin.
The counter is incremented only if the
OE
input is held
high, the n
CS
input is held low, and all configuration data
has not been transferred to the target device.
After configuration or when
OE
is low, the EPC1, EPC2 and
EPC1441 device drive
DCLK
low.
OE
387
Open-drain
bidirectional
Output enable (active high) and reset (active low). The
OE
pin connects to the n
STATUS
pin of the FPGA.
A low logic level resets the address counter. A high logic
level enables
DATA
and the address counter to count. If this
pin is low (reset) during configuration, the internal
oscillator becomes inactive and
DCLK
drives low. For more
information, refer to “Error Detection Circuitry” on page 9.
The
OE
pin has an internal programmable 1-k resistor in
EPC2 devices. If internal pull-up resistors are used, do not
use external pull-up resistors on these pins. You can
disable the internal pull-up resistors through the Disable
nCS and OE pull-ups on configuration device option.

n
CS
4910Input
Chip select input (active low). The n
CS
pin connects to the
CONF
_
DONE
pin of the FPGA.
A low input allows
DCLK
to increment the address counter
and enables
DATA
to drive out. If the EPC1 or EPC2 device
is reset (
OE
pulled low) while n
CS
is low, the device
initializes as the master device in a configuration chain. If
the EPC1 or EPC2 device is reset (
OE
pulled low) while n
CS
is high, the device initializes as a slave device in the chain.
The n
CS
pin has an internal programmable 1-k resistor
in EPC2 devices. If internal pull-up resistors are used, do
not use external pull-up resistors on these pins. You can
disable the internal pull-up resistors through the Disable
nCS and OE pull-ups on configuration device option.
n
CASC
61215Output
Cascade select output (active low).
This output goes low when the address counter has
reached its maximum value. When the address counter has
reached its maximum value, the configuration device has
sent all its configuration data to the FPGA. In a chain of
EPC1 or EPC2 devices, the n
CASC
pin of one device is
connected to the n
CS
pin of the next device, which permits
DCLK
to clock data from the next EPC1 or EPC2 device in
the chain. For single EPC1 or EPC2 device and the last
device in the chain, n
CASC
is left floating.
This pin is only available in EPC1 and EPC2 devices, which
support data cascading.
n
INIT
_
CONF
N/A 13 16 Open-Drain
Output
Allows the
INIT
_
CONF
JTAG instruction to initiate
configuration. The n
INIT
_
CONF
pin connects to the
n
CONFIG
pin of the FPGA.
If multiple EPC2 devices are used to configure an FPGA,
the n
INIT
_
CONF
of the first EPC2 device pin is tied to the
FPGA’s n
CONFIG
pin, while subsequent devices'
n
INIT
_
CONF
pins are left floating.
The
INIT
_
CONF
pin has an internal 1-k pull-up resistor
that is always active in EPC2 devices.
This pin is only available in EPC2 devices.
TDI
N/A 11 13 Input
JTAG data input pin. Connect this pin to VCC
if the JTAG
circuitry is not used.
This pin is only available in EPC2 devices.
TDO
N/A 1 28 Output
JTAG data output pin. Do not connect this pin if the JTAG
circuitry is not used.
This pin is only available in EPC2 devices.
TMS
N/A 19 25 Input
JTAG mode select pin. Connect this pin to VCC if the JTAG
circuitry is not used.
This pin is only available in EPC2 devices.

must be connected to VCC if VPP uses a 3.3-V
power supply (VPP = 3.3 V).
This pin is only available in EPC2 devices.
VPP
N/A 18 23 Power
Programming power pin. For the EPC2 device, this pin is
normally tied to VCC. If the VCC of the EPC2 device is 3.3 V,
tie VPP to 5.0 V to improve ISP time. For EPC1 and
EPC1441 devices, VPP must be tied to VCC.
This pin is only available in EPC2 devices.
