Overview

The PIC16F18346-E/SO is a high-performance 8-bit microcontroller from Microchip's eXtreme Low Power (XLP) family, featuring 28KB of Flash and a 32MHz core. This specific variant is rated for extended temperature ranges and includes Core Independent Peripherals (CIPs) designed to handle tasks without CPU intervention, making it suitable for functional safety applications.

Why Choose This Part

This MCU reduces system power consumption through its XLP modes and integrated Core Independent Peripherals like the Configurable Logic Cell (CLC) and Numerically Controlled Oscillator (NCO). It provides a robust safety feature set, including hardware-based memory scanning and a windowed watchdog, within a cost-effective 20-SOIC package.

Applications

Automotive Sensor Interface
Utilizes the integrated ADC and extended temperature rating to monitor sensors in harsh under-the-hood environments.
Industrial Safety Controllers
Leverages the Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC/SCAN) for functional safety compliance.
Battery-Powered Remote Nodes
Exploits XLP technology and a 1.2uA sleep current to extend the life of coin-cell operated IoT devices.
LED Lighting Control
Uses Complementary Waveform Generators (CWG) and PWMs to drive power FETs for dimming and color mixing applications.
