PIC16(L)F1574/5/8/9
14/20-Pin MCUs with High-Precision 16-Bit PWMs
Description
PIC16(L)F1574/5/8/9 microcontrollers combine the capabilities of 16-bit PWMs with Analog to suit a variety of applications.
These devices deliver four 16-bit PWMs with independent timers for applications where high resolution is needed, such as
LED lighting, stepper motors, power supplies and other general purpose applications. The core independent peripherals
(16-bit PWMs, Complementary Waveform Generator), Enhanced Universal Synchronous Asynchronous Receiver
Transceiver (EUSART) and Analog (ADCs, Comparator and DAC) enable closed-loop feedback and communication for
use in multiple market segments. The Peripheral Pin Select (PPS) functionality allows for I/O pin remapping of the digital
peripherals for increased flexibility. The EUSART peripheral enables the communication for applications such as LIN.
