Overview

The PIC16F18446-I/SO is an 8-bit eXtreme Low-Power (XLP) microcontroller featuring 28KB of Flash and integrated Functional Safety (FuSa) features. It operates at up to 32MHz and is designed for power-sensitive applications requiring hardware-level reliability and flexible peripheral pin mapping.

Why Choose This Part

This MCU offers a high memory-to-pin ratio with 28KB Flash in a 20-pin package, coupled with Microchip's Core Independent Peripherals (CIP) to reduce CPU overhead. The XLP technology ensures low power consumption in standby modes, while the 256 bytes of EEPROM provide reliable non-volatile storage for calibration data.

Applications

Functional Safety Systems
Utilizes hardware features like the Windowed Watchdog Timer (WWDT) and Memory Access Partition (MAP) to meet safety integrity requirements.
Battery-Powered Sensors
Leverages XLP technology and a low sleep current of 50uA for extended operation in remote monitoring applications.
Industrial Control Interfaces
Uses Peripheral Pin Select (PPS) and MSSP modules to manage I2C or SPI communication for industrial instrumentation.
LED Lighting Control
Employs the on-chip PWM and Data Signal Modulator (DSM) to manage complex dimming and signaling protocols.
