Overview

The PIC16F1779-I/PT is a high-performance 8-bit microcontroller from Microchip Technology featuring 28KB of Flash memory and a 32MHz clock speed. It is built on a C-compiler optimized RISC architecture and includes unique analog peripherals like Zero-Cross Detection and Programmable Ramp Generators for advanced power and motor control tasks. This 44-pin TQFP device is designed for applications requiring high-current I/O drive capabilities and low-power operation through XLP technology.

Why Choose This Part

The device offers significant flexibility through Peripheral Pin Select (PPS), allowing engineers to map digital peripherals to almost any I/O pin. Its 100mA total I/O output current capability simplifies designs by reducing the need for external driver components in light-load applications.

Applications

Intelligent Power Conversion
Utilizes the integrated Zero-Cross Detector (ZCD) and Programmable Ramp Generators (PRG) for switched-mode power supply control.
LED Lighting Control
Leverages multiple PWM channels and high-current drive I/Os to manage dimming and color mixing in complex lighting arrays.
Industrial Sensor Interfacing
Integrates analog peripherals with 2KB of RAM to process sensor signals before transmitting data via EUSART, SPI, or I2C.
Motor Control
Uses hardware timers and PWM modules to drive bridge circuits for DC and stepper motor applications.
