Overview

The PIC18F25K42-I/ML is an 8-bit microcontroller designed for functional safety applications, featuring 32KB of Flash and 2KB of RAM in a space-saving 28-QFN package. It operates at speeds up to 64MHz and integrates Core Independent Peripherals (CIPs) to handle hardware tasks without CPU intervention. This model includes advanced features like Direct Memory Access (DMA) and a Vectored Interrupt Controller to improve system response times and reduce power consumption.

Why Choose This Part

This MCU offers a Vectored Interrupt Controller for predictable latency and two DMA controllers for efficient data movement between peripherals and memory. Its hardware-based safety features, including the Windowed Watchdog and CRC with Memory Scan, simplify compliance with functional safety standards like IEC 60730 and ISO 26262.

Applications

Industrial Safety Controllers
Utilizes the built-in Windowed Watchdog Timer (WWDT) and hardware CRC to monitor system health in functional safety environments.
Automotive Sensor Interfacing
Interfaces with various vehicle sensors using its UART, I2C, and SPI peripherals with DMA to offload data transfer tasks.
Intelligent Lighting Control
Manages complex LED PWM patterns and DALI/DMX lighting protocols using dedicated hardware modules.
Battery Management Systems
Monitors cell voltage and temperature in low-power modes, drawing only 1uA in sleep while maintaining safety monitoring.

Getting Started

To begin development, use the MPLAB X IDE and the MPLAB XC8 compiler. Hardware debugging can be performed using the MPLAB PICkit 4 or MPLAB ICD 4 via the ICSP interface. Evaluation can be accelerated using the Curiosity Nano or PIC18F25K42 Curiosity development boards which offer integrated programmers.
