Table 2–57 lists the QDRII+ component reference and manufacturing information.
Flash
The development board supports a 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 FM bus that connects to
the flash memory and MAX II CPLD EPM2210 System Controller.
This 16-bit data memory interface can sustain burst read operations at up to 52 MHz
for a throughput of 832 Mbps. The write performance is 270 µs for a single word while
the erase time is 800 ms for a 128 K main block.
Table 2–60 lists the flash pin assignments, signal names, and functions. The signal
names and types are relative to the Arria V GX FPGA in terms of I/O setting and
direction.
