This datasheet lists the features of the PIC16C641, PIC16C642, PIC16C661 and PIC16C662 microcontrollers.
The PIC16C64X and PIC16C66X families are 8‑bit EPROM‑based microcontrollers featuring a high‑performance RISC core, up to 33 I/O pins, two analog comparators, and programmable voltage reference. They support a range of oscillator options and include power‑saving modes such as SLEEP and Watchdog Timer.
The document provides detailed specifications, pin diagrams for PDIP, SOIC, TQFP and windowed CERDIP packages, memory organization, peripheral features, and ordering information through the product identification system.
