Datasheet for the Microchip PIC16C433, provided as a 2.43 MB PDF file. The document contains the device pinout, memory organisation, peripheral descriptions, instruction set summary and DC/AC electrical characteristics needed to work with the part. As a C-series device it uses EPROM or one-time-programmable memory, so a replacement chip must be programmed with the correct firmware. Technicians use the pin map to locate supply, oscillator and reset pins and to confirm signal levels while diagnosing a fault.
