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 PIC16C620(A)/621(A)/622(A) family of microcontrollers is based upon Microchip’s mid-range architecture with an 8 level hardware stack and 35 14-bit instructions. These MCUs provide up to 10 MIPS, up to 2 Kbytes program memory with data memory of up to 128 bytes RAM. On board is a RC oscillator with ±1% accuracy.
