00 — Overview

What the PIC12F1571 does

The PIC12(L)F1571/2 are 8-pin microcontrollers featuring high-precision 16-bit PWMs and analog peripherals for applications like LED lighting, stepper motors, and power supplies. These devices operate at DC to 32 MHz with a sleep current of 20 nA at 1.8V. They support a voltage range of 1.8V to 5.5V across industrial and extended temperature grades. The family includes variants with up to 256 bytes of SRAM and three independent 16-bit PWMs. Key features include a 10-bit ADC, a 5-bit DAC, and an EUSART supporting LIN communication. The architecture offers C compiler optimization and a 125 ns minimum instruction cycle for efficient embedded control.
