Flash
The development board has two 512-Mb CFI-compatible synchronous flash device for
non-volatile storage of FPGA configuration data, board information, test application
data, and user code space.
Each interface has a 16-bit data bus and the two devices combined allow for x32 FPP
configuration. This device is part of the shared flash and MAX (FM) bus, which
connects to the flash memory and MAX V CPLD System Controller.
Each 16-bit data memory interface can sustain burst read operations at up to 52 MHz
for a throughput of 832 Mbps per device. The write performance is 270 µs for a single
word and 310 µs for a 32-word buffer. The erase time is 800 ms for a 128 K parameter
block.
Table 2–56 lists the flash pin assignments, signal names, and functions.
