When it was in beta testing, I had 30 bytes of rom left and no ram. I wanted to add some additional RAM locations for something, so I thought the logical choice would be the PIC16C711. I ordered 20 units for the final version, thinking they would be fine. They were the same price as the 71's. I also ordered a windowed unit to test with. I use the Microchip PICSTART-16B1 on the project bench. When I programmed the windowed part, everything worked well. When I tried to program the One Time Programmable units , I would get a write fault. I had one of the MicroEngineering programmers that I use in the field. It programmed all parts fine. Never could get an answer from Microchip about this. Haven't had another run-in with the part.
