Microchip PIC16LF1824-I/ST: A Comprehensive Technical Overview

The Microchip PIC16LF1824-I/ST represents a powerful and versatile 8-bit microcontroller within Microchip's extensive PIC16F family. Engineered for low-power operation and packed with a rich set of peripherals, it is an ideal solution for a wide array of embedded control applications, including consumer electronics, sensor nodes, battery-powered devices, and industrial control systems.

At the core of this device lies the enhanced PIC16 architecture with a nanowatt XLP technology foundation. It operates at a maximum frequency of 32 MHz, delivering a performance of 8 MIPS. A key defining feature is its exceptionally low power consumption. In sleep mode, the current draw can be as low as 20 nA, making it exceptionally suited for applications where energy efficiency is paramount and battery life is critical.

The PIC16LF1824 boasts 7 KB of self-read/write capable Flash program memory and 256 bytes of EEPROM data memory, providing ample space for code and non-volatile data storage. It is supported by 128 bytes of RAM, ensuring efficient data manipulation during operation.

Its integrated peripheral set is remarkably comprehensive for its class. Key features include:

mTouch capacitive sensing module: Allows for the implementation of touch interfaces (buttons, sliders) without external components, reducing system cost and complexity.

Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART): Facilitates serial communication protocols like RS-232, RS-485, and LIN bus for system connectivity.

Serial Peripheral Interface (SPI) and I²C (MSSP): Supports communication with a vast ecosystem of peripheral chips such as sensors, memory, and displays.

Complementary Waveform Generator (CWG): A highly flexible module for generating precise PWM signals, crucial for motor control and power conversion applications.

10-bit Analog-to-Digital Converter (ADC) with 12 channels: Enables the system to interface with a multitude of analog sensors and signals.

Two Configurable Logic Cells (CLC): Allows for the creation of custom logic functions directly in hardware, independent of the core, which can offload simple tasks and reduce interrupt overhead.

Housed in a space-saving 14-pin TSSOP (Thin Shrink Small Outline Package), the `-I/ST` suffix denotes the industrial temperature grade (-40°C to +85°C) and the tape-and-reel packaging option, making it suitable for robust environments and high-volume automated manufacturing.

ICGOODFIND: The Microchip PIC16LF1824-I/ST stands out as an ultra-low-power 8-bit MCU that punches well above its weight. Its potent combination of nanoWatt XLP technology, a rich integrated peripheral set including touch sensing and advanced PWM, and its small form factor make it an exceptional choice for designers seeking to maximize functionality and battery life in compact, cost-sensitive embedded designs.
