TMDSCNCD28388D: Questions regarding XDS100 emulation for custom board designs

Part Number: TMDSCNCD28388D

Hello,

I am trying to implement a XDS100v2 emulator on the FT2232HL based on the XDS100 software page and the reference design provided by TI:

https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_xds100.html

http://software-dl.ti.com/sdo/sdo_apps_public_sw/XDS/XDS100v2Schematic(rev2)-Setup.zip

I cant seem to find an alternative for the IS93C46D-GR EEPROM shown in the XDS100v2 reference design shown in the XDS100v2Schematic, but have been able to find the EEPROM used for the FTDI on the TMDSCNCD28388D card (93LC56C-I/SN). For using the FTDI program template provided by TI (for use with FT_Prog), are either of the EEPROMs usable, or does it strictly need to be the IS93C46D-GR? Additionally, is the CPLD strictly needed, even if the FTDI is being implemented as the sole board-flashing method, if so, are there suitable alternatives to the XC2C32A-6VQ44C that work with the code provided in the reference design?

Thanks in advance!

    Aaron,

    You will probably be fine to use an alternative EEPROM, but you will need to make sure that its basic functionality is the same (looks like SPI). I am not sure what the CPLD is, but I do not see the XC2C32A-6VQ44C on launchpads like the F28379D_LAUNCHXL, which have an onboard XDS100v2.

    Best Regards,
