Overview

The PIC16LF18324-I/SL is a versatile 8-bit microcontroller from Microchip's eXtreme Low Power (XLP) family, featuring 7KB of flash and 512 bytes of RAM in a compact 14-pin SOIC package. It operates at up to 32MHz and is specifically designed for battery-powered applications, offering a typical sleep current as low as 40nA. The device integrates Peripheral Pin Select (PPS) and Core Independent Peripherals to reduce CPU overhead and power consumption.

Why Choose This Part

The inclusion of Peripheral Pin Select (PPS) allows flexible I/O routing, simplifying PCB layout by mapping digital peripherals to any I/O pin. Its eXtreme Low Power (XLP) features, including Peripheral Module Disable (PMD), allow engineers to shut down unused logic to achieve industry-leading standby power metrics. The architecture is highly efficient for C compilers, providing a 16-level deep hardware stack and dedicated EEPROM for non-volatile data storage.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology and 40nA sleep current to maximize battery life in wireless environmental monitoring nodes.
Handheld Portable Devices
Low-voltage operation down to 1.8V and small 14-pin footprint make it ideal for compact, mobile consumer electronics.
Industrial Logic Controllers
Integrated EUSART and LINbus support enable robust communication in distributed industrial sensor networks.
Hardware Safety Monitoring
Features like the Windowed Watchdog Timer and Brown-out Reset provide reliable system supervision in safety-critical applications.

Getting Started

Development is supported by the MPLAB X IDE and the XC8 C Compiler. For hardware evaluation, the Curiosity High Pin Count (HPC) Development Board or a custom PCB can be used with a PICkit 4 or MPLAB ICD 4 in-circuit debugger. Use the MPLAB Code Configurator (MCC) plugin to quickly generate initialization code for the PPS and Core Independent Peripherals.
