Does anybody know which PIC exactly the SX replicated?

Hi!

I know that the SX replicates a particular PIC, albeit with extra hardware and much faster clock rate... anyone knows which PIC model it was?

Thanks!

You always have the facts or know where to find them

I have been called "The Librarian" by some.

I didn't see the answer to OP on the link but I thought SX was most similar to PIC16F54.

4K x 12 program space, so 12-bit instructions. A quick look on Wikipedia would indicate it as a fully expanded PIC12. PIC16's are 14-bit instructions.

PIC16F54 does have the 12 bit instructions.
PIC12 are all just 8 pin versions without all the io pins.
SX has the io pins and runs much faster.

I did say "fully expanded". The instruction set is that of the PIC12, not the PIC16. Ah, I didn't fully read that. So that part is a PIC12.

I didn't see it clear by looking at the wikipedia article...

PIC16F54 seems a good bet.
