PIC18F66K80-I/MR

PIC18F66K80-I/MR is Microchip’s 8‑bit PIC18 microcontroller in the PIC18F66K80 family. The “-I” suffix denotes Industrial temperature range (-40°C to +85°C), and “/MR” indicates Tape‑and‑Reel packaging. It combines a high‑performance 8‑bit core with on‑chip Flash program memory, RAM, and data EEPROM, plus a rich peripheral set suitable for embedded control, data acquisition, motor control, and small USB/communications tasks on compatible variants. Peripherals typically include USARTs, SPI, I2C, ADCs, timers, PWM, and capture/compare features. It runs at clock speeds that yield tens of MIPS, enabling compact, cost‑effective designs with moderate I/O needs. Development is via Microchip MPLAB X IDE using XC8 (and other) compilers, with debugging/driving options such as PICkit, ICD, or MPLAB REAL ICE. Before design, verify the exact memory sizes and peripheral counts for your specific device variant, and choose the appropriate package and temperature rating for your application.
