Overview

The PIC18F44K22-I/PT is a high-performance 8-bit microcontroller from Microchip's XLP (eXtreme Low Power) family, featuring 16KB of Flash memory and a 64MHz maximum clock speed. This device integrates advanced analog peripherals, including a 5-bit DAC and a Charge Time Measurement Unit (CTMU) for capacitive touch sensing applications. It is designed for energy-sensitive applications requiring a balance of high-speed processing and minimal power consumption.

Why Choose This Part

This microcontroller offers a significant performance boost for 8-bit designs with its 64MHz internal oscillator and single-cycle hardware multiplier. Its XLP technology ensures industry-leading low power consumption in sleep modes, while the C-compiler optimized architecture simplifies the development of complex firmware in high-level languages.

Applications

Capacitive Touch Interfaces
Utilizes the integrated CTMU and internal multiplexing to implement robust touch buttons, sliders, and proximity sensors.
Battery-Powered Instrumentation
Ideal for handheld devices requiring 1.4uA standby current and integrated analog-to-digital conversion.
Lighting Control
Leverages hardware PWM modules and dual rail-to-rail comparators for efficient LED dimming and power regulation.
Industrial Sensor Nodes
Uses the 12-bit ADC and Fixed Voltage Reference (FVR) to provide stable measurements in environments with varying supply voltages.

Getting Started

Development typically centers around the MPLAB X IDE and the XC8 compiler. Hardware debugging is best achieved using the MPLAB PICkit 4 or ICD 4 in-circuit debuggers connected to the 44-TQFP package via the ICSP interface. For rapid prototyping, the Curiosity High Pin Count (HPC) Development Board is a compatible platform.
