The Microchip PIC16F720T-I/SS is a high-performance, cost-effective 8-bit microcontroller built on PIC® architecture, designed for a wide range of embedded control applications. Combining a rich set of peripherals with nanoWatt XLP ultra-low-power technology, this MCU is an ideal solution for battery-operated and power-sensitive designs, from consumer electronics to industrial systems and IoT nodes.

Core Architecture and Performance

At its heart lies an enhanced mid-range 8-bit RISC CPU core operating at up to 16 MHz, delivering a performance of 16 MIPS. The device features 3.5 KB of Flash program memory and 128 bytes of RAM, providing sufficient resources for complex control algorithms and data handling. Its 256 bytes of High-Endurance Flash (HEF) memory offer robust storage for critical data, capable of enduring up to 100,000 erase/write cycles—far exceeding standard EEPROM.

Key Peripherals and Integration

A standout feature of the PIC16F720 is its high level of integration, which minimizes external components and reduces system cost. It includes:

Analog-to-Digital Converter (ADC): A 10-bit ADC with up to 12 channels, enabling precise measurement of analog signals from sensors.

Timers and CCP: Multiple timers (8-bit and 16-bit) and a Capture/Compare/PWM (CCP) module provide essential functions for generating waveforms, measuring time intervals, and controlling motors.

Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART): Supports both RS-232, RS-485, and LIN bus communication, facilitating robust serial data exchange.

mTouch™ Capacitive Sensing: Integrated hardware for implementing capacitive touch interfaces without external components, ideal for modern user input controls.

NanoWatt XLP Technology: This technology enables extremely low power consumption in Sleep mode (down to 20 nA), making it perfect for applications that demand long battery life.

Application Guide

The combination of these features opens doors to numerous applications:

Consumer Electronics: Remote controls, touch panels, and small appliances benefit from its low power and touch sensing capabilities.
