PIC12(L)F1571/2 8-Pin MCU with High Precision 16-bit PWMs Description: PIC12(L)F1571/2 microcontrollers combine the capabilities of 16-bit PWMs with Intelligent Analog to suit a variety of applications. These devices deliver three 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 Intelligent Analog (ADCs, Comparator and DAC) enable closed loop feedback and communication for use in multiple market segments. The EUSART peripheral enables the communication for applications such as LIN.
