Overview

The PIC18F27K42-E/ML is an 8-bit microcontroller from Microchip's PIC18 K42 family, featuring 128KB of Flash memory and 8KB of RAM. It is designed for high-performance, low-power applications with a maximum clock speed of 64MHz and specialized Core Independent Peripherals (CIPs) that reduce CPU overhead. The device includes 1KB of EEPROM and integrated DMA controllers for efficient data handling without constant processor intervention.

Why Choose This Part

This MCU excels in task offloading through its two Direct Memory Access (DMA) controllers and Vectored Interrupt Capability, which ensures deterministic interrupt latency. The Core Independent Peripherals allow complex functions like signal measurement and logic control to run while the CPU is in Sleep mode, drawing as little as 1uA.

Applications

Industrial Sensor Nodes
Utilizes the 12-bit ADC with Computation (ADC2) and low-power modes for remote monitoring and data logging.
Motor Control Interfacing
Leverages hardware PWMs and Vectored Interrupts to provide precise timing for motor drive signals.
Communication Bridges
Uses dual DMA channels and multiple UART/SPI/I2C interfaces to manage high-throughput data translation between protocols.
Automotive Interior Systems
Suitable for non-safety critical cabin controls via LINbus connectivity and extended temperature range operation.
