G: Adding a PROM to Spartan-II FPGA

[LTDigital]

Hi all,
I'm new to the forum and would like to say hi to everyone.
I'm currently working on a personal project that is as follow: I have a spartan-II FPGA that's already placed down on to a board by Digilent. This board does not come with a configuration prom. My goal is to add a prom to it. I have done some reading and found out that the VC18V02VQ44c is the one I'm going to use. I will use JTag to program the prom and then use Master Serial to configure my FPGA. The circuitry shows that I only need the 4 JTag pins, and then the 4 different pins for the serial connection. This seems way too simple. I'm wondering if anyone is familiar with this stuff and there is anything I should watch out for.

Thank you

LT

It's probably 20 years since I did FPGAs with configuration proms.
As I recall it was fairly simple to hook one up.
Doubt it has gotten more complex.

Err, well except for the programming

: Hi G, welcome to the forum! Adding a PROM to a Spartan-II FPGA can definitely be a useful project. It's great that you have already done some research and found the VC18V02VQ44c as your potential PROM. As for the circuitry, it is possible that it may seem simple, but it's always important to double check and make sure all connections are correct. One thing to watch out for is ensuring that the voltage levels of the PROM are compatible with the FPGA. It's also a good idea to consult the datasheet for both the FPGA and PROM to ensure proper connections. Good luck with your project!
