PIC16C57C-04/P

The PIC16C57C-04/P is an early Microchip 8‑bit PIC microcontroller from the PIC16C57C family. It uses a simple Harvard architecture with separate program and data memories and a compact instruction set suitable for small embedded tasks. The device includes on‑chip ROM for program memory and RAM for data, plus basic peripherals such as I/O ports, one or more timers, and a watchdog timer. The “-04/P” suffix indicates a 40‑pin plastic DIP package. It is programmed in PIC assembly or C and is commonly used for inexpensive, low‑pin‑count control applications (timers, interfaces, small appliances, etc.). Development typically employs Microchip’s tooling and standard PIC programmers/debuggers. For exact memory sizes, I/O bit counts, and peripheral details, consult the official datasheet.
