Overview

The PIC16LF1554-I/SL is an 8-bit microcontroller from Microchip's Extreme Low Power (XLP) family, designed for applications where minimal current draw is critical. It features a 32MHz internal oscillator and 4KB of Flash memory in a compact 14-pin SOIC package. This device is optimized for battery-operated systems that require efficient processing and precise analog integration.

Why Choose This Part

The primary advantage is the eXtreme Low Power (XLP) technology, achieving standby currents as low as 20nA. The integration of 16-level hardware stack and automatic context saving improves interrupt performance and code efficiency compared to older 8-bit architectures.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology to maintain ultra-low standby current in periodic wake-up monitoring applications.
Portable Medical Devices
Ideal for hand-held diagnostic tools that require a small physical footprint and long battery shelf life.
Handheld Consumer Electronics
Suitable for simple user interfaces and control logic in devices where power efficiency is a primary design constraint.

Getting Started

Developers should use the MPLAB X IDE and the XC8 Compiler for firmware development. Hardware debugging is supported through Microchip tools such as the MPLAB PICkit 4 or Snap using the ICSP interface. Evaluation can be performed by mounting the 14-SOIC package to a standard breakout board for prototyping.
