Overview

The PIC16F18856-I/SS is an 8-bit microcontroller from Microchip's XLP (eXtreme Low Power) family, featuring 28KB of Flash and a comprehensive suite of Core Independent Peripherals (CIPs). It is specifically designed for functional safety and low-power applications, incorporating hardware features like a Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC) with memory scanning. The device operates up to 32MHz and includes a 10-bit ADC with computation capabilities to reduce CPU overhead in sensor interfacing.

Why Choose This Part

This MCU excels in power efficiency through its XLP technology and Peripheral Pin Select (PPS), which allows flexible I/O mapping to simplify PCB routing. The inclusion of Core Independent Peripherals allows the MCU to handle complex tasks like PWM generation and signal measurement while the core remains in a low-power state.

Applications

Functional Safety Systems
Utilizes the hardware CRC/Scan and Windowed Watchdog Timer to meet safety standards in industrial and consumer electronics.
Battery-Powered IoT Sensors
Leverages XLP technology and Sleep currents as low as 400nA to extend battery life in remote monitoring applications.
Capacitive Touch Sensing
Integrated Hardware Capacitive Voltage Divider (CVD) support enables robust touch interfaces with minimal software complexity.
Signal Conditioners
The Zero-Cross Detect (ZCD) and Fixed Voltage Reference (FVR) modules facilitate precise AC power control and analog signal processing.
