Mach X Chip Burning Problem

alchazz2 · Guest

I just got a new Mach X programmer as my old PRO16 can't do the newer chips. I have burned 16F648As successfully.

When I try to burn a 12C508A, it fails. I can burn them successfully with the PRO16.

With the PRO16, there is a window which shows you where to place the IC for correct burning. The Mach X does not have such a window. I just put the chips in so pin 1 of the chip is at pin 1 of the burner.

Is this correct?

If not, where is the info for doing it correctly?

OK, I got an answer from CCS support. They say to always put pin 1 of the chip at pin 1 of the ZIF socket.

They still did didn't explain the failure to program the 12C508As though.

I just tried to program a PIC12C509A (windowed version) using MACH-X with chip in the ZIF socket. Latest software and firmware (1.121/0.41). Verify fails. Have not tried contact CCS support, will probably just use other programmer.

I wonder what the problem is? Is it because the chips are "obsolete."

So far, all I've heard back from CCS is that the chips are supported. They asked some questions as if they were going to look into it.

I think there are non-obsolete parts in the same family that use the same programming interface.
