Overview

The PIC18F25K42-E/MV is an 8-bit microcontroller designed for safety-critical and high-performance embedded control applications. Operating at up to 64MHz, it features 32KB of Flash memory and integrates advanced Core Independent Peripherals (CIPs) that handle tasks without CPU intervention. This specific variant is extended-temperature rated (E) and housed in a compact 28-pin UQFN package.

Why Choose This Part

This MCU excels in efficiency by offloading data management to its dual DMA controllers and hardware-vectored interrupt system, reducing software complexity. The Device Information Area (DIA) provides factory-calibrated data for the temperature sensor and fixed voltage reference, simplifying high-precision analog designs.

Applications

Functional Safety Systems
Utilizes integrated hardware features like the Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC) with Memory Scan for ASIL and SIL compliance.
Automotive Sensor Interfaces
The extended temperature rating and vectored interrupt controller make it suitable for under-the-hood monitoring and LINbus networking.
Intelligent Power Control
Employs two DMA controllers and a system bus arbiter to manage data flow between peripherals and memory with minimal CPU overhead.
Industrial Automation
Leverages configurable logic cells and a 12-bit ADC with computation for localized processing in factory sensor nodes.
