Manufacturer Identifier
The Spartan-3AN In-System Flash memory is architecturally similar to the Atmel
DataFlash SPI Flash memories, as shown in
relates to the Atmel DataFlash product family.
Table 6-9: Spartan-3AN ISF Memory and Similar Atmel DataFlash Memory
The first byte of the ISF Information, shown in
manufacturer code. This byte is identical for all Spartan-3AN FPGAs. The JEDEC identifier
for the ISF memory is 0x1F. This value is different than the JEDEC code for Xilinx, which
is 0x49. The Spartan-3AN FPGA product identifier is available via JTAG.
