Each MAX II device contains a flash memory block within its floorplan.
On the EPM240 device, this block is located on the left side of the device.
For the EPM570, EPM1270, and EPM2210 devices, the flash memory
block is located on the bottom-left area of the device. The majority of this
flash memory storage is partitioned as the dedicated configuration flash
memory (CFM) block. The CFM block provides the non-volatile storage
for all of the SRAM configuration information. The CFM automatically
downloads and configures the logic and I/O at power-up providing
instant-on operation.
See Hot Socketing & Power-On Reset in MAX II Devices for more
information on configuration upon power-up.
A portion of the flash memory within the MAX II device is partitioned
into a small block for user data. This user flash memory (UFM) block
provides 8,192 bits of general-purpose user storage. The UFM provides
programmable port connections to the logic array for reading and for
writing. There are three LAB rows adjacent to this block, with column
numbers varying by device.
