Interlock FPGA choice
Posted: Tue May 04, 2021 8:29 pm
Hi,
We are working on an interlock circuit where we'd like to use a FPGA in combination with a MCU to in a switching circuit. The basic requirement is that both switches can't be on at the same time, so the FPGA will enforce the timing such that switch X has to be off for z amount of time before switch Y can be turned on. Some things that seem nice to have:
- instant on would be nice, but not sure if absolutely required
- enough logic to implement a few counters and some simple logic
- be re-programmable in-system so we can change the operation if needed
Can you recommend quicklogic parts we should look at?
Thanks!
