Microchip PIC18F25K22T-I/SO: A Comprehensive Technical Overview

The Microchip PIC18F25K22T-I/SO represents a robust and versatile 8-bit microcontroller within Microchip's extensive PIC18F K2 family. Engineered for a wide array of embedded control applications, this device combines enhanced computational performance with a rich set of peripherals, all while maintaining a focus on power efficiency. Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, it is well-suited for space-constrained and automated assembly processes.

At the core of the PIC18F25K22T-I/SO lies an enhanced PIC18 architecture with a 16-bit instruction set. Operating at speeds up to 64 MHz, delivering 16 MIPS (Million Instructions Per Second), the core ensures responsive performance for complex control loops and data processing tasks. A key feature of this microcontroller is its nanowatt technology, which enables extremely low power consumption through multiple dynamically selectable power modes, making it ideal for battery-powered and energy-sensitive applications.

The device is equipped with 32 KB of self-read/write capable Flash program memory and 1536 bytes of RAM, providing ample space for application code and data handling. Furthermore, it includes 1024 bytes of Data EEPROM for storing critical parameters that must be retained even after a power cycle.

Its peripheral set is both comprehensive and modern. Communication is facilitated by multiple serial interfaces, including EUSART, SPI, and I2C™ modules, allowing for seamless connectivity with sensors, displays, and other ICs. For analog signal acquisition, it integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 24 channels, providing high-resolution measurement capabilities. The module also features two analog comparators for quick signal monitoring. Control applications are supported by multiple 16-bit and 8-bit timers/counters and two CCP (Capture/Compare/PWM) modules, which are essential for generating precise pulse-width modulated signals for motor control or measuring external digital signals.

The "T" in its part number signifies that it is tape and reel packaged, catering to high-volume manufacturing environments. Its industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environmental conditions.

ICGOODFIND: The PIC18F25K22T-I/SO is a highly integrated and power-efficient 8-bit MCU. Its blend of strong performance, extensive memory, a rich peripheral set, and industrial robustness makes it an excellent choice for applications in industrial control, automotive, consumer electronics, and Internet of Things (IoT) edge nodes.
