The PIC16C range of Microcontrollers from Microchip are 8-bit CMOS MCUs that incorporate Microchip’s PIC® architecture into a variety of pin and package options, from space efficient 14-pin devices to feature-rich 64-pin devices. Now supplanted by Flash based variants these devices are still popular in legacy designs. For new applications PIC16F variants should be considered.

The PIC16C5x family of Microcontrollers is based upon Microchip’s baseline architecture with a 2 level hardware stack and 33 12-bit instructions. These MCUs provide up to 10 MIPS, up to 3 Kbytes program memory with data memory of up to 73 bytes RAM. On board is a RC oscillator with ±1% accuracy.
