描述 Description

PIC16(L)F157X 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) and Analog (ADCs, Comparator and DAC) can be configured for closed loop feedback control or other application needs. The Peripheral Pin Select (PPS) functionality allows for I/O pin remapping of the digital peripherals for increased flexility. The EUSART peripheral enables serial communication?for use in multiple market segments, such as LIN applications.



Debug Support
