Overview

The PIC18F25K42-E/SS is an 8-bit microcontroller from Microchip's high-performance PIC18 family, featuring XLP (eXtreme Low Power) technology and functional safety (FuSa) features. It operates at up to 64MHz and integrates 32KB of Flash memory with Core Independent Peripherals (CIPs) that reduce CPU overhead. This specific variant is rated for extended temperature ranges and comes in a 28-pin SSOP package.

Why Choose This Part

The integration of Direct Memory Access (DMA) and Vectored Interrupts significantly improves data handling efficiency compared to standard 8-bit architectures. It also includes hardware-based CRC/Scan and a Windowed Watchdog Timer, making it a robust choice for applications requiring functional safety compliance.

Applications

Safety-Critical Industrial Controls
Utilizes hardware-based Functional Safety features like a Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC) with memory scanning for reliable operation.
Battery-Powered Remote Sensors
Leverages XLP technology and a 0.4 uA sleep current to extend battery life in periodic wake-up applications.
Automotive Body Electronics
Suitable for door modules, lighting control, and sensor interfacing using its 24-channel 10-bit ADC and EUSART/I2C/SPI connectivity.
