Overview

The PIC16LF1824-I/ST is an 8-bit microcontroller from Microchip's Enhanced Mid-Range family featuring eXtreme Low Power (XLP) and mTouch capacitive sensing technology. It operates at up to 32MHz with 7KB of Flash memory and 256 bytes of EEPROM in a space-efficient 14-TSSOP package. This low-voltage 'LF' variant is optimized for battery-operated systems, consuming as little as 20uA in sleep mode.

Why Choose This Part

The XLP technology provides industry-leading low power consumption, including a 7.5uA run current at 3.0V in LP Oscillator mode. It features a high level of peripheral integration, such as an 11-channel 10-bit ADC, I2C/SPI/UART connectivity, and automatic context saving for faster interrupt handling.

Applications

Capacitive Touch Interfaces
Utilizing integrated mTouch technology for robust touch buttons and sliders in consumer electronics.
Remote Sensors
Low-power environmental or security sensors requiring long battery life and periodic data logging to EEPROM.
Portable Medical Devices
Compact handheld diagnostic tools that benefit from 1.8V operation and low sleep current.
Lighting Control
Smart LED controllers using the four on-board PWM channels and flexible internal oscillator block.

Getting Started

Developers can begin using the MPLAB X IDE and the XC8 compiler for software development. Hardware programming and debugging are supported via the MPLAB PICkit 4 or Snap in-circuit debuggers using the ICSP interface. For rapid prototyping, Microchip offers various Curiosity development boards or the PIC16F1824/1828 Evaluation Board.
