PIC16C63A/65B/73B/74B 8-Bit Microcontrollers 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 PIC16C63A/65B/73B/74B 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 5 MIPS, 7 Kbytes program memory with data memory of 192 bytes RAM. On board is a RC oscillator with ±1% accuracy. Features 35 Instructions
