Overview

The PIC16F18346-I/SO is an 8-bit eXtreme Low Power (XLP) microcontroller featuring 28KB of Flash and a robust suite of Core Independent Peripherals. It is specifically designed for functional safety applications, offering hardware-based monitoring and reliability features in a compact 20-pin SOIC package.

Why Choose This Part

This MCU reduces system power consumption through its XLP modes and increases reliability with functional safety (FuSa) features. The Core Independent Peripherals allow for high-speed hardware response times while keeping the 32MHz CPU in low-power states.

Applications

Functional Safety Controllers
Utilizes integrated hardware features to meet safety standards in industrial and automotive subsystems.
Battery-Powered Remote Sensors
Leverages XLP technology with sleep currents as low as 0.4 uA to extend operational life in portable devices.
Signal Modulation and Logic
Uses the Configurable Logic Cell (CLC) and Numerically Controlled Oscillator (NCO) to handle complex signal processing without CPU intervention.
Lighting Control
Employs the Complementary Waveform Generator (CWG) and PWMs for efficient half-bridge and full-bridge drive control.
