Microchip PIC16F1704-I/ST: A Comprehensive Technical Overview

The Microchip PIC16F1704-I/ST represents a versatile and cost-effective 8-bit microcontroller within the enhanced mid-range PIC16F1xxx family. Housed in a compact 14-pin TSSOP package, this device is engineered for a wide array of embedded control applications, leveraging its robust peripheral set and core independent peripherals (CIPs) to reduce CPU overhead and boost system efficiency.

At its heart lies the high-performance 8-bit RISC CPU core, operating at up to 32 MHz with a 16-level deep hardware stack and 35 instructions. The device features 3.5 KB of Flash program memory and 128 bytes of RAM, providing sufficient resources for numerous control tasks. A key architectural advantage is its suite of advanced, CIPs. These include a 12-bit Analog-to-Digital Converter (ADC) with Computation (ADC2) technology, which allows for automated analog signal analysis—such as averaging, filtering, and threshold comparison—while the core sleeps, drastically reducing power consumption in sensor applications.

Further enhancing its analog capabilities are two 8-bit Digital-to-Analog Converters (DACs) and two comparators. These integrated analog modules make the PIC16F1704 exceptionally suited for closed-loop control systems, sensor interface, and power management without requiring external components.

For digital control and communication, the microcontroller is equipped with multiple serial communication modules, including EUSART (for UART), MSSP (for SPI and I2C), and a powerful Complementary Waveform Generator (CWG). The CWG is critical for generating precise PWM signals for controlling brushless DC (BLDC) motors, switching power supplies, and digital power conversion.

Development and debugging are streamlined through In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD) support, allowing for easy firmware updates and system troubleshooting. Its wide operating voltage range (2.3V to 5.5V) and low-power management modes make it an excellent choice for both line-powered and battery-operated devices.
