Introduction

This document lists the non-volatile memories on the FreeForm/PCI-104, their purpose, and how they can be erased.

List of Non-Volatile Memories

Manufacturer Part Number Type Designator Purpose Does Removal affect Board Function? Electrically Write Protected? Method of Writing and Erasing
Micron M25P32-VMF6P SPI Flash U10 FPGA configuration storage Yes, FPGA would have to always be configured by JTAG No, Write Protect pin is disabled Using Xilinx IMPACT tools
Micron M25P64-VMF6P

 

SPI Flash U11 Embedded software code storage, to be used by MicroBlaze or Power PC Only if you are trying to use MicroBlaze or Power PC No, Write Protect pin is disabled Using reference design provided by CTI, including FPGA & host software.
Atmel AT93C66A-10SU-2.7 EEPROM U9 PLX9056 configuration storage.  Sets the size of PCI memory windows and other functions No, by default the FPGA configures the PLX9056 directly over the local bus No, Write Protect pin is disabled Using PLX Software Development kit GUI tool PLX Mon
Or
Using reference design provided by CTI, including FPGA & host software.
Atmel AT93C66A-10SU-2.7

 

EEPROM U14 General FPGA parameters, like MAC address No, MAC address can be hardcoded in the FPGA code No, Write Protect pin is disabled Using reference design provided by CTI, including FPGA & host software.
