Overview

The PIC16F1575-I/SL is an 8-bit microcontroller featuring three 16-bit PWMs with independent timers, making it highly effective for precision lighting and power control. It operates at up to 32MHz with 14KB of Flash memory and includes Peripheral Pin Select (PPS) for flexible I/O routing in a compact 14-pin SOIC package.

Why Choose This Part

This MCU stands out due to its high-resolution 16-bit PWMs which are unusual for an 8-bit device of this size, allowing for extremely smooth transitions in lighting. The Peripheral Pin Select feature simplifies PCB layout by allowing digital peripherals to be mapped to almost any I/O pin.

Applications

LED Lighting Control
Utilizing the three independent 16-bit PWMs for high-resolution dimming and color mixing in RGB applications.
DC-DC Power Conversion
Leveraging the Complementary Waveform Generator (CWG) and PWMs to drive power MOSFETs in buck or boost configurations.
Automotive Interior Lighting
Using the integrated LINbus and UART support for networked cabin lighting systems.
Fan Control
Implementing closed-loop speed control for brushless DC fans using the on-board timers and PWM modules.
