概述

Description

PIC16C57C-04/P is an early Microchip 8‑bit PIC microcontroller in a 40‑pin DIP package. It belongs to the PIC16C57C family and uses a Harvard architecture with a 14‑bit instruction word. It has ROM program memory, RAM data memory, and a small set of peripherals: I/O ports, one or more timers, a watchdog timer, MCLR input, and an interrupt system. It can be clocked from an external oscillator in LP/XT/HS modes and typically runs from a single supply (commonly 4.5–5.5 V). Programming is done with PIC assembly or C using tools such as MPLAB X and a programmer (ICSP interface). The “-04/P” suffix indicates a specific package/speed variant; exact RAM/ROM sizes and I/O counts vary by revision, so consult the Microchip datasheet for precise specifications. Typical uses include simple timing, control tasks, and small embedded applications where a compact 8‑bit MCU is sufficient.
