NB2DSK01 - Configuration PROM

The NB2DSK01 uses a Xilinx Platform Flash Configuration PROM device (XCF08PFS48C) in which to store the system's firmware. The firmware gives the NB2DSK01 its 'smarts'.

Figure 1. Serial PROM device used to hold the NanoBoard firmware.

The XCF08PFS48C is a 48-pin device providing 8M of memory.

On power-up, the firmware is automatically loaded into the NanoTalk Controller.

Location on Board

The configuration PROM (designated U7) is located on the component side of the board – to the top-right of the NanoTalk Controller.

Schematic Reference

The configuration PROM can be found on Sheet 19 (XCF08PFS48C_FLASH.SchDoc, entitled FPGA Config XCF08PFS48C) of the motherboard schematics.
