Flash
The starter board supports two 1-Gb CFI-compatible synchronous flash device for
non-volatile storage of FPGA configuration data, board information, test application
data, and user code space. This device is part of the shared FSM bus that connects to
the flash memory, SSRAM, and MAX V CPLD 5M2210 System Controller.
This 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 buffer while the erase time is 800 ms for a 128 K array block.
Table 2–47 lists the flash pin assignments, signal names, and functions. The signal
names and types are relative to the Arria V GX in terms of I/O setting and direction.
