PDF datasheet of 1.77 MB for the Microchip PIC16C712 and PIC16C716 8-bit microcontrollers. The C designation means OTP or EPROM program memory, and both parts share an 18-pin pinout with analog-to-digital inputs. Technicians use it to look up pin functions, oscillator modes, reset circuitry and electrical limits while tracing a circuit. An OTP chip cannot be erased, so replacing it requires a blank part and a copy of the original firmware, which this document does not provide.
