Microchip PIC18F26K20T-I/ML 8-Bit Microcontroller Datasheet and Application Overview

The Microchip PIC18F26K20T-I/ML is a high-performance, enhanced 8-bit microcontroller from Microchip Technology's PIC18K family. It is engineered to deliver a powerful combination of low power consumption, high computational performance, and a rich set of integrated peripherals, making it an ideal solution for a vast array of embedded control applications in the industrial, automotive, and consumer electronics sectors.

Housed in a compact 28-pin QFN (ML) package, this microcontroller is built on an enhanced PIC18 architecture with a 16-bit instruction set. A core standout feature is its nanowatt technology, which enables extremely low power consumption through multiple dynamically switchable power modes. This allows designs to achieve extended battery life, which is critical for portable and remote devices.

At its heart, the device operates at up to 64 MHz, providing a 16 MIPS performance from its internal oscillator. It features 64 KB of self-read/write capable Flash program memory and 3,856 bytes of RAM, ensuring ample space for complex application code and data handling. The integration of a powerful 10-bit Analog-to-Digital Converter (ADC) with up to 13 channels, multiple Enhanced PWM modules, and communication interfaces like EUSART, SPI, and I2C provides a comprehensive set of tools for interfacing with sensors, actuators, and communication networks.

Key peripherals highlighted in the datasheet include:

Enhanced Capture/Compare/PWM (ECCP) Modules: For precise control of motors and power converters.

Complementary Waveform Generator (CWG): Outputs complementary signals for advanced motor control and half-bridge/full-bridge power conversion with dead-band control.

mTouch Sensing Module: Supports the implementation of capacitive touch sensing interfaces without external components.
