Overview

The PIC16F18345-E/SS is an 8-bit functional safety-ready microcontroller featuring eXtreme Low Power (XLP) technology for battery-sensitive applications. It operates at up to 32MHz with 14KB of Flash memory and includes Core Independent Peripherals (CIPs) that reduce CPU overhead. This variant is rated for extended temperature ranges, making it suitable for automotive and industrial environments.

Why Choose This Part

This MCU offers a high degree of flexibility through Peripheral Pin Select (PPS) and Configurable Logic Cells (CLC), which allow for customized hardware logic without taxing the CPU. Its 5.5V maximum VDD support simplifies integration with legacy industrial systems while maintaining ultra-low power consumption in standby modes.

Applications

Safety-Critical Monitoring
Utilizes integrated hardware features for functional safety to monitor system parameters in industrial or automotive applications.
Battery-Powered Remote Sensors
Leverages XLP technology with sleep currents as low as 0.5uA to extend the life of coin-cell operated devices.
Signal Modulation and Waveform Generation
Uses the integrated Complementary Waveform Generator (CWG) and Numerically Controlled Oscillator (NCO) for power conversion and motor control.
Distributed Control Nodes
Functions as a secondary controller communicating via LINbus or I2C in complex multi-processor systems.
