This document describes the features and characteristics of the PIC18F1220/1320 series high-performance enhanced flash microcontrollers with 10-bit A/D conversion and nanoWatt technology, introduced by Microchip Technology in 2004.
The PIC18F1220 and PIC18F1320 are 18‑, 20‑ and 28‑pin high‑performance microcontrollers featuring nanoWatt low‑power technology, enhanced flash memory, and a 10‑bit A/D converter. The document provides detailed electrical characteristics, pin diagrams, and functional descriptions for each peripheral.
Key sections cover oscillator options, power‑managed modes, flash and EEPROM memory specifications, timer modules, enhanced capture/compare/PWM, USART, and special CPU features such as fail‑safe clock monitor and self‑programming capability.
