Overview

The PIC18F24K22-I/SO is a high-performance 8-bit microcontroller featuring Microchip eXtreme Low Power (XLP) technology and 16KB of Flash memory. It operates at speeds up to 64MHz and includes a robust set of peripherals such as a 10-bit ADC, dual MSSP modules for I2C/SPI, and two enhanced UARTs.

Why Choose This Part

This MCU offers a high clock speed of 64MHz in a standard 28-pin SOIC package, providing significant processing power for an 8-bit device. It includes 256 bytes of dedicated data EEPROM for non-volatile storage and maintains a wide operating voltage range from 2.3V to 5.5V.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology to minimize sleep current down to 10nA, extending the life of portable sensor nodes.
Capacitive Touch Interfaces
Leverages the integrated Charge Time Measurement Unit (CTMU) for implementing touch buttons and proximity sensors.
Industrial Protocol Converters
Dual UART and dual SPI/I2C interfaces allow the device to act as a bridge between multiple communication standards.
Motor Control Timing
Uses on-board PWM modules and timers to manage speed and direction for small DC motors.
