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

The PIC16F684T-I/ST from Microchip Technology represents a versatile and cost-effective solution in the world of 8-bit microcontrollers. Housed in a compact 14-pin TSSOP package, this device is engineered for space-constrained and power-sensitive applications, offering a robust set of features that make it suitable for a wide range of embedded control tasks.

At its core, the microcontroller operates with an enhanced mid-range PIC® core with a 20 MHz internal oscillator, delivering up to 5 MIPS performance. It includes 7 KB of Flash program memory and 256 bytes of RAM, providing sufficient resources for many control algorithms and data handling routines. A standout feature is its rich set of peripherals, which includes a 10-bit ADC with 11 channels, two analog comparators, and an enhanced Capture, Compare, and PWM (ECCP) module. This makes it particularly adept for analog signal processing and motor control applications.

The device also supports multiple communication protocols via its MSSP (Master Synchronous Serial Port) module, which can be configured for either SPI or I2C, enabling seamless interaction with sensors, memories, and other peripheral ICs. Additionally, its nanowatt technology ensures ultra-low power consumption, making it ideal for battery-operated devices.

Application Guide

A common use case for the PIC16F684T-I/ST is in consumer electronics, such as remote controls, small appliances, and LED lighting systems, where its analog capabilities and compact form factor are highly advantageous. In industrial settings, it serves well in sensor interfaces, power management systems, and as a dedicated controller for brushless DC (BLDC) motors using its ECCP module.

Designers can leverage Microchip’s MPLAB® X IDE and the PICKit™ programmer for code development and debugging. The microcontroller’s integration reduces external component count, lowering overall system cost and complexity.
