Overview

The PIC16F18855-I/SS is a 28-pin 8-bit microcontroller featuring Microchip XLP technology for ultra-low power consumption and functional safety features. Operating at up to 32MHz with 14KB of Flash memory, it includes core independent peripherals that offload timing-critical tasks from the CPU. This MCU is particularly suited for battery-powered sensor nodes and safety-critical applications requiring high reliability.

Why Choose This Part

The device excels in power efficiency with multiple low-power modes including Doze and Idle to maintain operation while minimizing current draw. Its Core Independent Peripherals (CIP) reduce software overhead and improve system response times for real-time control loops.

Applications

Battery-Powered IoT Sensors
Utilizes XLP technology and Sleep modes down to 400nA to maximize battery life in remote sensing applications.
Safety-Critical Control
Integrated CRC with Memory Scan and Windowed Watchdog Timer (WWDT) support functional safety requirements for industrial monitoring.
Smart Home Appliances
24 ADC channels and 4 PWM channels allow for complex human-interface and motor control tasks in small appliances.
Signal Conditioning
Built-in 5-bit DAC and Fixed Voltage Reference simplify analog circuit design without external components.

Getting Started

Development is supported by the MPLAB X IDE and the XC8 compiler, with the MPLAB Code Configurator (MCC) available for rapid peripheral setup. For hardware evaluation, the Curiosity High Pin Count (HPC) Development Board or a PIC16F18855 Curiosity Nano can be used with an MPLAB PICkit 4 programmer/debugger.
