Microchip PIC16F1718T-I/SS: A Comprehensive Technical Overview

The Microchip PIC16F1718T-I/SS stands as a robust and versatile 8-bit microcontroller within the enhanced mid-range PIC16F171 family. Engineered for a wide array of embedded control applications, this device combines a powerful core with a rich set of advanced peripherals, making it a compelling choice for designs requiring precision analog, communication, and control capabilities.

At its heart, the microcontroller utilizes an enhanced 8-bit RISC architecture with a 49-instruction set. Operating at a maximum frequency of 32 MHz, it delivers a performance of 8 MIPS. The core features a deep hardware stack and intelligent peripherals that can operate autonomously, reducing CPU intervention and power consumption. The device is equipped with 14 KB of Flash program memory and 1 KB of RAM, providing ample space for complex application code and data handling.

A significant strength of the PIC16F1718T-I/SS lies in its advanced analog integration. It includes a 12-bit Analog-to-Digital Converter (ADC) with up to 35 channels, offering high-resolution measurements for sophisticated sensor interfacing. Complementing the ADC are several key analog modules:

Two 8-bit Digital-to-Analog Converters (DACs) for generating precise analog reference voltages or waveforms.

Two operational amplifiers (Op Amps) that can be configured for gain or filtering, simplifying analog signal conditioning externally.

Two comparators with programmable voltage reference, ideal for threshold detection.

Zero-Cross Detect (ZCD) module, crucial for triac control in AC power management applications.

For control and communication, the MCU is exceptionally well-equipped. It features two Capture, Compare, PWM (CCP) modules and three Enhanced CCP (ECCP) modules. These support a variety of PWM modes, including half-bridge and full-bridge output for motor control. The ECCP includes hardware dead-band control and automatic shutdown, which are critical for safe and efficient power drive. For serial communication, the device offers:

EUSART supporting RS-485, RS-232, and LIN compatibility.

I2C/SPI communication ports.

MSSP (Master Synchronous Serial Port).

The core and its peripherals are managed by a suite of Clock and Timer resources, including multiple 8-bit and 16-bit timers. A key feature for low-power applications is the Hardware Limit Timer (HLT), which can place the device into Sleep mode autonomously after a predefined period of inactivity.

Housed in a 28-pin SSOP (Shrink Small Outline Package), the PIC16F1718T-I/SS is designed for space-constrained applications. Its operating voltage ranges from 2.3V to 5.5V, and it boasts an extended temperature range of -40°C to +85°C, ensuring reliability in industrial and automotive environments. The "T" in its part number signifies it is supplied in tape and reel packaging, optimized for automated assembly processes.

ICGOODFIND: The Microchip PIC16F1718T-I/SS is a highly integrated 8-bit MCU that excels in applications demanding precision analog control and robust communication. Its standout features, including the 12-bit ADC, on-board Op Amps and DACs, and advanced ECCP modules, make it an ideal single-chip solution for motor control, power conversion, industrial control, and Internet of Things (IoT) endpoints, offering both performance and cost-effectiveness.
