Microchip PIC18F24K22-I/SO 8-Bit Microcontroller Technical Overview and Application Guide

The Microchip PIC18F24K22-I/SO represents a robust and highly integrated 8-bit microcontroller unit (MCU) within Microchip's extensive PIC18 family. Engineered for a wide array of embedded control applications, this device combines high computational performance with low power consumption and a rich set of peripheral features, making it a versatile solution for designers.

Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, the PIC18F24K22 is built on an enhanced mid-range architecture with a 16-bit instruction set. At its core is an optimized CPU capable of operating at up to 64 MHz, delivering a performance of 16 MIPS (Million Instructions Per Second). This ensures swift and efficient execution of control algorithms and real-time tasks.

A significant technical advantage of this MCU is its nanowatt technology, which enables extremely low power consumption. It features multiple software-selectable power modes (Run, Idle, and Sleep), allowing designers to create applications that are highly efficient, a critical requirement for battery-powered and portable devices.

The memory configuration is substantial for an 8-bit controller. It includes 32 Kbytes of self-read/write capable Flash program memory, 1536 bytes of RAM, and 1024 bytes of EEPROM data memory. This provides ample space for complex application code and data storage, supporting in-circuit serial programming (ICSP) for easy firmware updates.

Its peripheral set is exceptionally rich:

Analog-to-Digital Converter (ADC): A 10-bit module with up to 13 channels, enabling precise measurement of analog sensors.

Timers: Includes four timers (Timer0 to Timer3) for various timing and counting operations.

Communication Interfaces: Equipped with EUSART (Enhanced Universal Synchronous Asynchronous Receiver Transmitter) for RS-232/485 communication, MSSP (Master Synchronous Serial Port) module supporting both I²C and SPI protocols, and a dedicated ECCP (Enhanced Capture/Compare/PWM) module for advanced motor control and power conversion applications.

Application areas for the PIC18F24K22-I/SO are diverse. Its combination of analog, control, and communication peripherals makes it ideal for:

Industrial Control Systems: Sensor interfacing, data logging, and actuator control.
