This document describes the PIC18FXX2 high-performance, enhanced flash microcontrollers with 10-bit A/D conversion developed by Microchip Technology Inc.
The PIC18FXX2 family offers a high‑performance 8‑bit RISC core with up to 10 MIPS operation, 10‑bit ADC, multiple timer modules, and a range of communication peripherals such as USART, SPI, and I²C. It supports a wide voltage range (2.5 V–5.5 V for low‑power parts, 4.2 V–5.5 V for standard parts) and operates from -40 °C to +125 °C depending on the temperature grade.
Key features include a 8 × 8 hardware multiplier, up to 32 KB of linear program memory, 1.5 KB of data memory, programmable brown‑out reset, watchdog timer, and various low‑power modes. The device is supplied in multiple packages (PDIP, SOIC, TQFP, PLCC) and includes extensive development support through Microchip's MPLAB tools.
