Nop,
12Fxxx F=flash series. you're suppose to be able to reprogram them more than few thousand times if you don't set CODE PROTECT ON configuration bit on your device programmer.
regards
Even if you set Code Protect ON, you can still reprogram them hundreds if not thousands of times. All Code Protect does is prevent the code from being read back.
I have noticed some Flash PICs will fail to reprogram unless they are ERASED first. You may want to try that.
