Microchip PIC16F684T-I/SL 8-Bit Microcontroller Overview and Application Guide

The Microchip PIC16F684T-I/SL is a high-performance, cost-effective 8-bit microcontroller built on an enhanced mid-range core architecture. This device is part of Microchip’s extensive PIC® MCU family and is designed to deliver a powerful yet efficient solution for a wide range of embedded control applications. Housed in a compact 14-pin SOIC package, it is particularly suited for space-constrained designs requiring a rich set of peripherals and low power consumption.

At its core, the PIC16F684T-I/SL operates at up to 20 MHz with an internal oscillator, offering a solid balance of processing speed and power efficiency. It features 3.5 KB of Flash program memory, 128 bytes of RAM, and 256 bytes of EEPROM data memory, providing ample space for both code and data storage in many control applications. Its enhanced CPU core includes a hardware multiplier, accelerating arithmetic operations and enabling more complex computations.

A key strength of this microcontroller lies in its versatile peripheral set. It integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 8 channels, making it ideal for sensor interfacing and analog signal measurement. The inclusion of two comparators and a Capture/Compare/PWM (CCP) module offers precise timing control for applications like motor driving, LED dimming, and power supply regulation. Furthermore, it boasts an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) for serial communication (UART, SPI, I2C™), facilitating easy connection to other digital devices, sensors, or PC interfaces.

Power management is a critical design consideration, and the PIC16F684T-I/SL excels with its nanowatt-technology. It features multiple power-saving modes (Sleep, Idle) that drastically reduce current consumption, extending battery life in portable and remote applications. Its wide operating voltage range (2.0V to 5.5V) further enhances its suitability for battery-powered products.

Typical applications for this robust MCU are diverse. It is perfectly suited for:

Consumer Electronics: Remote controls, smart toys, and portable gadgets.
