This document describes the features and characteristics of the PIC16C55X(A) series products, including high-performance RISC CPU, peripheral features, and special microcontroller features.
The PIC16C55X(A) family comprises EPROM‑based 8‑bit CMOS microcontrollers offered in 18‑pin DIP, SOIC and SSOP packages. They feature a high‑performance RISC core with a 35‑instruction set, an eight‑level deep hardware stack, and up to three interrupt sources. The devices include 13 configurable I/O pins, an 8‑bit timer/counter with programmable prescaler, and a watchdog timer with its own RC oscillator.
Key specifications such as program memory size (512 B to 2 KB), data RAM (80 B to 128 B), operating voltage (2.5 V–5.5 V), and maximum clock frequency (20 MHz) are listed, along with packaging options and ordering information. The datasheet also outlines development support tools, programming options, and product identification codes for ordering.
