Overview

The PIC16F18344-I/SO is an 8-bit eXtreme Low Power (XLP) microcontroller featuring 7KB of Flash and a 32MHz internal oscillator. It includes Functional Safety (FuSa) features such as a Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC) with memory scanning to ensure high reliability in critical applications.

Why Choose This Part

This MCU offers Peripheral Pin Select (PPS) for flexible I/O mapping, allowing engineers to optimize PCB layouts by assigning digital peripherals to any pin. It combines 5V tolerance on I/O with high-resolution analog capabilities, including 17 channels of 10-bit ADC and a 5-bit DAC.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology with sleep currents as low as 40nA to extend service life in field-deployed wireless nodes.
Functional Safety Monitors
Integrated hardware CRC and WWDT facilitate compliance with safety standards in industrial and consumer appliances.
Automotive Body Electronics
Peripheral Pin Select (PPS) and LINbus compatibility allow for flexible routing and communication in automotive subsystems.
Lighting Control
Employs four PWM channels and 17 ADC channels for precise LED dimming and environmental sensing.
