Overview

The PIC12LF1571-I/SN is a low-voltage 8-bit microcontroller featuring an enhanced mid-range CPU core and 1KB of flash memory. Part of Microchip's LF family, it is optimized for 1.8V to 3.6V operation with specialized low-leakage characteristics for battery-powered systems. The device integrates three high-resolution 16-bit PWMs and internal voltage references within a compact 8-pin SOIC package.

Why Choose This Part

This LF variant provides significantly lower leakage during flash operation compared to standard F-series parts, maximizing efficiency at 1.8V. The 16-level hardware stack and 32MHz internal oscillator provide more computational overhead than typical sub-8-bit MCUs while maintaining a low pin count.

Applications

LED Lighting Control
Utilizing three independent 16-bit PWMs for high-resolution dimming and color mixing in small-form-factor lighting fixtures.
Battery-Powered Sensing
Ideal for remote sensors where 5.5uA run currents and 1.8V operation extend the life of coin cell batteries.
Simple System Logic Replacement
Consolidating glue logic and timing functions into a single 8-pin programmable device to reduce PCB area.

Getting Started

Designers can use the MPLAB X IDE with the XC8 compiler for development. The part is programmed via the two-pin In-Circuit Serial Programming (ICSP) interface using tools like the MPLAB PICkit 4 or ICD 4. For prototyping, the Curiosity Development Board (DM164137) provides a compatible environment for 8-bit PIC MCUs.
