Microchip PIC18LF44K22-I/PT: Low-Power, High-Performance 8-Bit Microcontroller

The Microchip PIC18LF44K22-I/PT represents a versatile and highly capable 8-bit microcontroller, designed to deliver a compelling blend of low-power operation and high-performance processing. As a member of Microchip’s extensive PIC18 family, this device is engineered to meet the demanding requirements of modern embedded systems, including portable, battery-powered, and energy-sensitive applications.

At the heart of the PIC18LF44K22 lies an enhanced PIC18 core with a 16-bit instruction set and a 32-level deep hardware stack. Operating at up to 64 MHz, it achieves 16 MIPS performance, enabling efficient execution of complex control algorithms and real-time tasks. The microcontroller integrates 16 KB of Flash program memory and 768 bytes of RAM, providing ample space for both code and data in a wide range of applications.

A defining feature of this device is its exceptional power management capability. It supports multiple operating modes, including Run, Idle, and Sleep, allowing developers to fine-tune power consumption based on application needs. The core operates at voltages as low as 1.8V, making it ideal for systems powered by batteries or energy harvesting sources. NanoWatt Technology ensures that power draw is minimized in all modes, significantly extending battery life in portable devices.

The peripheral set is both rich and flexible. It includes multiple communication interfaces such as EUSART, SPI, and I2C™, facilitating easy connection to sensors, displays, and other system components. It also features a 10-bit Analog-to-Digital Converter (ADC) with up to 13 channels, multiple timers, and two comparators for analog signal conditioning. The inclusion of mTouch™ capacitive sensing hardware support allows for the implementation of modern user interfaces without external components.

Housed in a 44-pin TQFP package, the PIC18LF44K22-I/PT offers a compact footprint while providing up to 36 I/O pins, each configurable with interrupt-on-change capability for responsive event handling.

ICGOODFIND: The PIC18LF44K22-I/PT is a robust, full-featured 8-bit MCU that stands out for its ultra-low-power operation and strong processing performance, making it an excellent choice for power-conscious embedded designs requiring reliable control and connectivity.
