Overview

The PIC16F18856-I/MV is an 8-bit microcontroller from Microchip's PIC16 family featuring XLP (eXtreme Low Power) technology and functional safety (FuSa) features. It integrates 28KB of Flash memory, a 10-bit ADC with Computation (ADC2), and Core Independent Peripherals (CIPs) to reduce CPU overhead in timing and control applications.

Why Choose This Part

This MCU offers a high degree of flexibility through Core Independent Peripherals, allowing the CPU to remain in low-power modes while hardware handles complex tasks. Its UQFN package provides a compact 4x4mm footprint, making it ideal for space-constrained designs requiring 25 I/O pins.

Applications

Functional Safety Controllers
Utilizes the Hardware Limit Timer (HLT) and Windowed Watchdog Timer (WWDT) to meet safety standards in industrial and consumer appliances.
Battery-Powered Sensors
Leverages XLP technology and Peripheral Module Disable (PMD) to extend battery life in remote sensing applications.
Power Supply Monitoring
Uses the integrated ADC2 for automated signal filtering and threshold comparison without waking the core.
Automated Control Systems
Employs Configurable Logic Cells (CLC) to create custom hardware logic for high-speed signal routing.
