Overview

The PIC18F46K22-E/PT is an 8-bit microcontroller from Microchip's XLP (eXtreme Low Power) family, featuring 64KB of Flash memory and a 44-pin TQFP package. It operates at speeds up to 64MHz with a wide operating voltage range, making it suitable for power-sensitive applications requiring robust peripheral sets like dual UARTs and integrated EEPROM. This specific 'E' temperature grade variant is rated for extended operation from -40 degrees C to +125 degrees C.

Why Choose This Part

It offers a high-performance 16MHz internal oscillator that can be scaled to 64MHz via an internal 4x PLL, reducing the need for external crystals. The architecture includes a 31-level hardware stack and priority-level interrupts, providing more sophisticated execution flow than standard 8-bit cores.

Applications

Industrial Sensor Nodes
Leverages the 12-bit ADC with auto-acquisition and the integrated 1KB EEPROM for local calibration data storage in harsh environments.
Automotive Body Electronics
Utilizes the extended temperature rating and XLP technology for cabin controls or monitoring systems that must maintain low standby current.
Battery-Powered Handhelds
The eXtreme Low Power (XLP) modes, including Sleep currents as low as 20uA, extend battery life in portable instrumentation.
Motor Control Interfacing
Uses the 8x8 single-cycle hardware multiplier and multiple PWM channels to manage basic motor driver logic and feedback loops.

Getting Started

Development is supported by the MPLAB X IDE and the XC8 C Compiler. For hardware debugging and programming, use the MPLAB PICkit 4 or MPLAB ICD 4 connected via the ICSP interface. The Curiosity High Pin Count (HPC) Development Board is a common platform for prototyping with 44-pin PIC18 devices.
