Overview

The PIC16F18326-I/SL is an 8-bit microcontroller from Microchip's eXtreme Low Power (XLP) family, featuring 28KB of Flash and a 32MHz internal oscillator. It is specifically designed with Functional Safety (FuSa) features to assist in achieving ISO 26262 or IEC 61508 certifications in safety-critical applications. The device includes Core Independent Peripherals (CIPs) such as DMA and PWM which reduce CPU overhead and power consumption.

Why Choose This Part

This MCU provides a robust 28KB Flash memory and 2KB RAM in a compact 14-pin package, offering a high feature-to-size ratio. Its XLP architecture and 5V tolerance make it versatile for both low-power battery applications and standard industrial 5V logic environments. The inclusion of hardware DMA and FuSa support allows for more complex, reliable firmware designs than typical 8-bit controllers.

Applications

Safety-Critical Sensors
Utilizing integrated hardware features for functional safety in industrial monitoring equipment.
Battery-Powered IoT Nodes
Taking advantage of XLP technology and sleep currents as low as 40uA for extended field life.
Handheld Medical Devices
Small footprint 14-SOIC package for portable diagnostic or monitoring tools.
Motor Control Feedback
Using CIPs like PWM and timers to handle motor tasks with minimal CPU intervention.
Automotive Interior Lighting
Managing LED strings and LINbus communication in cost-sensitive vehicle sub-modules.

Getting Started

Developers should use the MPLAB X IDE and the XC8 Compiler for firmware development. Hardware debugging and programming are supported via the MPLAB PICkit 4 or Snap in-circuit debuggers. The MPLAB Code Configurator (MCC) is recommended to quickly set up the Core Independent Peripherals and pin mapping.
