Microchip datasheet for the PIC16C781 and PIC16C782, PIC16 microcontrollers with integrated analog peripherals such as an operational amplifier, comparators, ADC and DAC, delivered as a 2.98 MB PDF. It documents pin functions, analog module configuration, oscillator choices and electrical ratings. Useful when tracing analog signal paths around the controller, checking reference voltages and confirming supply pins on a board. These are OTP or EPROM devices in most packages, so replacement normally requires a pre-programmed part with the original code.
