PIC12/16(L)F157X
MCUs with High-Precision 16-Bit PWMs Product Brief
Description
PIC12(L)F1571/2 and 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 up to 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.
