Overview

The PIC16F18446-E/GZ is an 8-bit eXtreme Low-Power (XLP) microcontroller featuring 28KB of Flash and integrated Functional Safety (FuSa) features. Operating at up to 32MHz, it includes a 12-bit ADC with Computation (ADC2) and Memory Access Partitioning to ensure code integrity in safety-critical environments. Its 20-pin UQFN package and wide 2.5V to 5.5V operating range make it suitable for space-constrained industrial applications.

Why Choose This Part

This MCU offers Core Independent Peripherals (CIPs) that handle tasks without CPU intervention, significantly reducing power consumption and latency. The 28KB Flash and 2KB RAM provide ample space for complex C-code implementations while the hardware-based Memory Access Partition protects bootloader and application code sections.

Applications

Industrial Safety Sensors
Utilizes integrated hardware features like the Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC/SCAN) to meet functional safety requirements.
Battery-Powered Remote Nodes
Leverages XLP technology and a 1.6uA sleep current to extend battery life in periodic monitoring systems.
Automotive Sensor Interfaces
The extended temperature rating (-E suffix) and LINbus/UART support enable robust communication in vehicle cabin or engine compartment sub-modules.
Smart Power Supplies
Uses the integrated DAC, high-speed comparators, and PWM peripherals for digital control of power conversion stages.
