Overview

The PIC18F46K22-I/MV is a high-performance 8-bit microcontroller from Microchip's XLP (eXtreme Low Power) family, featuring 64KB of Flash and 3.8KB of RAM. It operates at speeds up to 64MHz and integrates a wide array of peripherals including dual I2C/SPI ports and a Charge Time Measurement Unit (CTMU) for capacitive touch sensing. This MCU is designed for applications requiring a balance of high-speed processing and ultra-low power consumption in a compact 40-pin UQFN package.

Why Choose This Part

This device offers a high MIPS-per-watt ratio with 64MHz operation at 5V, making it suitable for legacy 5V systems and modern low-voltage designs down to 2.3V. Its XLP technology and dedicated SR Latch peripheral provide hardware-level logic functions that reduce CPU overhead and power consumption.

Applications

Capacitive Touch Sensing
Utilizes the integrated Charge Time Measurement Unit (CTMU) for implementing robust touch buttons and sliders.
Battery-Powered Remote Sensors
Leverages XLP technology to achieve sleep currents as low as 10nA, extending the life of coin-cell operated devices.
Industrial Control Loops
Uses multiple PWM channels, timers, and dual EUSARTs to manage motor control or complex sensor networks at 64MHz.
Data Logging
The 1KB of on-chip EEPROM provides reliable non-volatile storage for calibration data and system logs.

Getting Started

Begin development using the MPLAB X IDE and the XC8 compiler. Hardware debugging and programming are supported through the MPLAB PICkit 4 or ICD 4 tools via the In-Circuit Serial Programming (ICSP) interface. For rapid prototyping, the Curiosity High Pin Count (HPC) Development Board is a compatible hardware platform.
