Datasheet covering Microchip PIC12C5xx 8-pin microcontrollers, a widely used baseline family with EPROM or OTP program memory, provided as a 1.57 MB PDF. It describes pin assignments, internal RC oscillator and its calibration, sleep and wake-up behaviour, instruction set and electrical specifications. These chips appear in remotes, chargers and small consumer gadgets. Use the pin diagram to probe supply and I/O lines, and remember that OTP versions cannot be erased, so a replacement needs the original program written to it.
