Description
Number of flash
devices used
• CFI Parallel Flash: 1–16
• Altera Active Serial ×4: 1,2,4
• Quad SPI Flash: 1,2,4
• NAND Flash: 1,2,4
Specifies the number of flash memory devices
connected to the PFL IP core. Allows up to four
flash memory devices.
Largest flash
density
• CFI Parallel Flash: 8 Mbit–4
Gbit
• NAND Flash: 512 Mbit/2
Gbit - Micron(NAND)
• 1 Gbit - Micron (MT29)
Specifies the density of the flash memory device to
be programmed or used for FPGA configuration.
If you have more than one flash memory device
connected to the PFL IP core, specify the largest
flash memory device density.
For CFI flash, select the density that is equivalent
to the sum of the density of two CFI flashes. For
example, if you use two 512-Mb CFI flashes, you
must select CFI 1 Gbit. (Available only if you
select CFI Parallel Flash or NAND Flash.)
Flash interface data
width
• CFI Parallel Flash: 8, 16, or
32 bits
• NAND Flash: 8 bits or 16
bits
Specifies the flash data width in bits. The flash data
width depends on the flash memory device you
use. For multiple flash memory device support, the
data width must be the same for all connected
flash memory devices.
For CFI flash, select the flash data width that is
equivalent to the sum of the data width of two CFI
flashes. For example, if you are targeting dual P30
or P33 solution, you must select 32 bits because
each CFI flash data width is 16 bits. (Available
only if you select CFI Parallel Flash or NAND
Flash.)
User control
flash_nreset
pin
On or Off
Creates a
flash_nreset
pin in the PFL IP core to
connect to the reset pin of the flash memory
device. A low signal resets the flash memory
device. In burst mode, this pin is available by
default.
When using a Spansion GL flash device, connect
this pin to the
RESET
# pin of the flash device.
(Available only if you select CFI Parallel Flash.)
Quad SPI flash
device manufac‐
turer
• Macronix
• Micron
• Spansion
Specifies the device manufacturer of the quad SPI
flash. (Available only if you select Quad SPI
Flash.)
Quad SPI flash
device density
8 Mbit–256 Mbit
Specifies the density of the quad SPI flash to be
programmed or used for FPGA configuration.
(Available only if you select Quad SPI Flash.)
