FX2LP GPIF Interface for 32bit data exchange

[r_shivakumar]

Hi,

I am using FX2LP Cy7c68013a-128 usb controller. 

There are examples provided in Getting Started application notes for GPIF Single word transactions.

I would like to know if there is any example or knowledge base article explaining implantation of GPIF Double word transactions.

My requirement is to read/write 32bit register value from FPGA attached to Cy7c68013a-128  chip through GPIF interface.
GPIF interface data Bus width is 16bits.

Thanks,
Shivakumar

Hi Shivakumar,

In FX2LP, GPIF is only 8 bit or 16 bit wide.

You may take a look at FX3 which has a 32-bit data bus: https://www.cypress.com/file/140296/download
