FT2232H FMC FT245 Style asynchronous FIFO Mode

[Coretels]

Hello,

I'm trying to interface to the FTDI FT2232H chip in FT245 Style asynchronous FIFO Mode to get a higher throughput over USB without needing to mess with the USB stack. I'm looking to get around 5MB/s throughput ultimately. Planning to use asynchronous as it's a bit easier.

I'm having trouble trying to figure out what configuration i should use in FMC in order to get this going? It seems all i need is an 8 bit address bus, read strobe, write strobe and buffer full/empty

(from https://ftdichip.com/wp-content/uploads/2020/08/TN_167_FIFO_Basics.pdf)

I'm getting quite confused with the PSRAM,NAND,SDRAM configurations.

Any advice is appreciated.

Thanks!

Hi,

maybe try on SPI (up to 54Mb ), looks more easy than (ab-) using the FMC memory interface.
