Overview

The PIC16F1574-I/P is an 8-bit microcontroller from Microchip Technology featuring a 32MHz clock speed and 7KB of Flash memory. Housed in a 14-pin PDIP package, it includes four 16-bit PWMs with independent timers, making it particularly well-suited for high-resolution drive and control applications.

Why Choose This Part

This MCU offers high-resolution 16-bit PWMs which are uncommon in small 14-pin packages, allowing for precise signal generation. Its Enhanced Mid-Range core provides efficient execution at 32MHz while maintaining low power consumption in sleep modes.

Applications

LED Lighting Control
Utilizing the 16-bit PWM modules for precise dimming and color mixing in architectural or automotive interior lighting.
Closed-Loop Fan Control
Implementing PID control loops for thermal management using the internal 10-bit ADC and high-resolution PWM outputs.
Education and Prototyping
The 14-pin through-hole PDIP package is ideal for breadboarding and teaching embedded systems fundamentals.
LIN Bus Nodes
Acting as a local interconnect network slave for simple automotive or industrial control nodes.

Getting Started

Developers can use the MPLAB X IDE and the XC8 C Compiler for firmware development. Hardware debugging and programming are supported via the In-Circuit Serial Programming (ICSP) interface using tools like the MPLAB PICkit 4 or Snap.

Also Consider

PIC16F1824-I/P MCHPMicrochip Technology - Offers an integrated I2C/SPI port (MSSP) which is absent on the 1574 if digital sensor interfacing is required.
