Microchip PIC16C432 datasheet, supplied as a 1.61 MB PDF. This OTP microcontroller includes an integrated LIN bus transceiver, which places it in automotive body electronics and similar networked modules. The document covers the pinout, LIN interface, comparators and electrical characteristics. Technicians use it to identify the bus, supply and clock pins when diagnosing a module that does not communicate. As an OTP part, a replacement requires the original program code, not included in this datasheet.
