This document describes the features and characteristics of the PIC17 series microcontrollers produced by Microchip Technology Inc., including instruction set, operating speed, hardware multiplier, interrupt capability, stack depth, addressing modes, and peripheral features.
The PIC17C4X family consists of 40‑ and 44‑pin 8‑bit CMOS microcontrollers with EPROM or ROM memory. The datasheet details core features such as a 16‑level deep hardware stack, hardware multiplier, multiple timers, PWM, capture inputs, and a universal synchronous asynchronous receiver‑transmitter (USART). It also lists the various device types (C, LC, CR, LCR) and packaging options.
Key specifications include operating frequencies up to 33 MHz, voltage ranges from 2.5 V to 6.0 V, up to 454 bytes of RAM, and 33 I/O pins with high‑current sink/source capability. The document also provides pin diagrams, electrical characteristics, and ordering information for the different variants.
