Overview

The PIC18F25K42-I/SS is an 8-bit microcontroller featuring 32KB of Flash and 2KB of RAM, designed for performance-intensive and functional safety applications. It operates up to 64MHz and integrates Core Independent Peripherals (CIPs) and Direct Memory Access (DMA) to reduce CPU overhead. Part of the eXtreme Low Power (XLP) family, it is optimized for battery-powered systems requiring high reliability.

Why Choose This Part

This MCU offers a 31-level deep hardware stack and an extended instruction set optimized for C compilers, improving code density and execution speed. The inclusion of DMA and Vectored Interrupts provides faster response times for real-time control compared to standard 8-bit architectures.

Applications

Safety-Critical Monitoring
Utilizes integrated hardware features like the Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC) with memory scanning to meet functional safety requirements.
Battery-Powered IoT Nodes
Leverages XLP technology and Sleep modes down to 0.4 uA to extend the life of remote sensors and connected devices.
Advanced Sensor Interfacing
The DMA controller and Peripheral Pin Select (PPS) allow for efficient data movement from I2C, SPI, or UART sensors without constant CPU intervention.
