Overview

The PIC18F27K42-E/SS is an 8-bit microcontroller from Microchip's PIC18 K42 family featuring 128KB of Flash memory and integrated XLP (eXtreme Low Power) technology. Operating at speeds up to 64MHz, it combines a rich set of Core Independent Peripherals (CIPs) with Direct Memory Access (DMA) to handle data intensive tasks with minimal CPU intervention.

Why Choose This Part

This MCU offers a significant memory footprint for an 8-bit device with 128KB Flash and 1KB EEPROM, supporting complex firmware and non-volatile data storage. The integration of DMA and Core Independent Peripherals allows for high-throughput data movement and complex logic operations at a 64MHz clock rate while maintaining low power consumption.

Applications

Industrial Sensor Nodes
Utilizes 24 ADC channels and 10-bit resolution to monitor multiple analog inputs in harsh environments.
Battery-Powered Handhelds
Leverages XLP technology and a 1.15uA standby current for extended operational life in portable equipment.
Real-Time Control Systems
Uses 16-bit timers and DMA to manage complex timing tasks without taxing the 8-bit RISC core.

Getting Started

Development is best supported through the MPLAB X IDE and the MPLAB Code Configurator (MCC) for visual peripheral setup. Hardware prototyping can be performed using the PIC18F27K42 Curiosity Nano evaluation board or by using an MPLAB PICkit 4 in-circuit debugger via the ICSP interface.
