PIC12F1572T-I/MF

PIC12(L)F1571/2 microcontrollers combine the capabilities of 16-bit PWMs with 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 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.
