Overview

The PIC16F18856-E/SO is a 28-pin 8-bit microcontroller featuring Microchip's eXtreme Low Power (XLP) technology and Functional Safety (FuSa) features. Operating at up to 32MHz with 28KB of Flash memory, it incorporates Core Independent Peripherals (CIPs) that reduce CPU overhead for timing and signal processing tasks. This specific E-grade variant is designed for extended temperature environments and reliable operation in industrial or automotive control systems.

Why Choose This Part

The inclusion of Core Independent Peripherals allows for complex logic and timing functions to run autonomously, freeing the CPU for other tasks and reducing power consumption. Its 5.5V maximum operating voltage provides high noise immunity and simplified interfacing in 5V legacy systems compared to 3.3V-only microcontrollers.

Applications

Industrial Safety Systems
Utilizes the Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check with Memory Scan (CRC/SCAN) to meet functional safety requirements.
Battery-Powered Remote Sensors
Leverages XLP technology and Low-Power BOR (LPBOR) to extend battery life in monitoring applications requiring periodic wake-ups.
Motor Control and Power Conversion
Employs the hardware limit timers (HLT) and PWM modules to manage power stages without constant CPU intervention.
Long-Haul Wired Communication
Integrated EUSART and LINbus compatibility allow for robust data exchange in distributed industrial networks.

Getting Started

Develop firmware using the MPLAB X IDE and the XC8 Compiler, which includes specialized optimizations for the enhanced mid-range 8-bit architecture. For rapid prototyping, use the MPLAB Code Configurator (MCC) to graphically initialize the Core Independent Peripherals and I/O pins. Hardware debugging can be performed using the MPLAB PICkit 4 or Snap in-circuit debugger via the ICSP interface.
