The PIC16F1574 microcontroller combines capabilities of 16-bit PWMs with analog

The Microchip PIC16F1574 microcontroller is versatile MCU, delivering four 16-bit PWM (pulse width modulation) with independent timers for applications where high resolution is needed, including – but not limited to –LED lighting and color mixing, motor control and switch mode power supplies. 

The PIC16F1574 MCU combines closed-loop control and communication capabilities into a small form factor, enabling increased precision for drive and control in cost-sensitive applications. It is distinguished from other MCUs in Microchip’s 157x family by offering a pin count of 14, 512 bytes SRAM, and 7Kb program flash memory, among other unique features. 

This MCU’s core independent peripherals (16-bit PWMs, complementary waveform generator) and analog (ADCs, comparator and DAC) can be configured for closed-loop feedback control or for other application needs. The peripheral pin select (PPS) functionality allows for I/O pin remapping of the digital peripherals, while the EUSART (enhanced USART) peripheral enables serial communication for use in multiple market segments, such as LIN (local interconnect network) applications.
