Microchip PIC16LF1829-I/SS 8-Bit Microcontroller Overview and Application Guide

The Microchip PIC16LF1829-I/SS is a high-performance, low-power 8-bit microcontroller based on Microchip’s enhanced mid-range PIC® architecture. This device is built using nanoWatt XLP technology, making it particularly suitable for battery-powered and energy-sensitive applications. Housed in a 20-pin SSOP package, it offers a compact footprint ideal for space-constrained designs while delivering a robust set of peripherals.

At its core, the microcontroller operates at up to 32 MHz, providing a good balance between processing speed and power consumption. It features 14 KB of Flash program memory and 1024 bytes of RAM, offering ample space for embedded applications. A key strength of the PIC16LF1829 lies in its rich integration of advanced peripherals. These include:

- mTouch capacitive sensing hardware for implementing touch interfaces without external components.

- Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) and Serial Peripheral Interface (SPI) for robust communication.

- Two I²C/SPI modules supporting both master and slave modes.

- 5-channel 10-bit Analog-to-Digital Converter (ADC) for precision sensor data acquisition.

- Two Capture/Compare/PWM (CCP) modules and a 5-bit Digital-to-Analog Converter (DAC) for analog control.

A major advantage is its ultra-low-power performance. The device can operate down to 1.8V, and its current consumption in Sleep mode can be as low as 20 nA, dramatically extending battery life in portable devices.

Application Guide

This MCU is exceptionally versatile. Common applications include:

- Consumer Electronics: Remote controls, touch-activated panels, and smart home devices benefit from its low power and capacitive sensing.
