Overview

The PIC18LF47K40-I/PT is a high-performance 8-bit microcontroller from Microchip's XLP (eXtreme Low-Power) family, operating at up to 64MHz. It features 128KB of Flash memory and 3.6KB of RAM, integrated into a 44-TQFP package for space-constrained embedded applications. This device is optimized for low-power operation with features like Peripheral Module Disable (PMD) and a 31-level hardware stack.

Why Choose This Part

This microcontroller offers extreme flexibility through Peripheral Pin Select (PPS), which allows developers to map digital peripherals to any I/O pin. Its XLP technology and Peripheral Module Disable (PMD) provide granular control over power consumption, making it ideal for energy-sensitive designs. Additionally, the inclusion of a Windowed Watchdog Timer (WWDT) and CRC/Memory Scan enhances system reliability in safety-critical environments.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology and low standby current of 0.5uA to maximize battery life in wireless monitoring nodes.
Industrial Control Interfaces
The 36 I/O pins and Peripheral Pin Select (PPS) allow for flexible routing of digital signals in complex automation panels.
Power Management Controllers
Leverages the Zero-Cross Detect (ZCD) and Fixed Voltage Reference (FVR) for precise AC/DC power monitoring and switching.
Handheld Consumer Electronics
Combines a high 64MHz clock speed with integrated 1KB EEPROM for storing user settings in portable devices.

Getting Started

Development is primarily supported by Microchip's MPLAB X IDE and the XC8 compiler. Hardware debugging can be performed using the MPLAB PICkit 4 or MPLAB ICD 4 via the ICSP interface. For rapid prototyping, the Curiosity High Pin Count (HPC) Development Board is a compatible platform for testing PIC18 K40 family features.
