PIC12F1572-E/MF

Microcontrollers Overview

The PIC12F1572-E/MF is an 8-bit microcontroller from the PIC12(L)F157x family, manufactured by Microchip Technology. It features a 32 MHz operating speed and utilizes a C Compiler Optimized RISC architecture with only 49 instructions. The device includes up to 3.5 Kbytes of Flash program memory and 256 bytes of Data SRAM. Key peripherals include three 16-bit PWMs, a Complementary Waveform Generator (CWG), Enhanced Universal Synchronous Asynchronous Receiver Transceiver (EUSART), a 10-bit Analog-to-Digital Converter (ADC), a comparator, and a 5-bit Digital-to-Analog Converter (DAC). It operates within a voltage range of 2.3V to 5.5V and supports industrial temperature ranges.

Microcontrollers Feature Summary

• Integrates three 16-bit Pulse-Width Modulation modules with independent timers for high-resolution control applications.

• Features an Enhanced Universal Synchronous Asynchronous Receiver Transceiver supporting LIN communication protocols.
• Provides analog capabilities including a 10-bit ADC, a comparator, and a 5-bit DAC for signal processing.

Microcontrollers Applications

• LED lighting systems requiring high-resolution color mixing
• Stepper motor control applications
• Power supply management circuits
• LIN bus communication interfaces

Microcontrollers Procurement Notes

Verify the specific ordering suffix '-MF' corresponds to the DFN-8 package and Industrial temperature grade (-40°C to +85°C) as defined in the official datasheet. Confirm that the 'E' suffix indicates the Extended temperature variant if required, although standard datasheets typically list -I/MS or -E/MF variants. Ensure compatibility with In-Circuit Serial Programming requirements via the RA0 and RA1 pins.

Microcontrollers Selection Notes

Select this component when high-resolution pulse-width modulation is required within an 8-pin footprint. The inclusion of three independent 16-bit PWMs and a Complementary Waveform Generator makes it suitable for complex analog control loops. Consider the 256-byte RAM limit for application complexity and verify that the 2.3V to 5.5V operating voltage range aligns with the system power supply design.

Microcontrollers Part Context

This device belongs to the PIC12(L)F157x series of 8-bit Flash microcontrollers. It shares the same core architecture and peripheral set as the PIC12F1571, differing primarily in memory size and specific peripheral availability. The series is designed for cost-sensitive applications requiring advanced analog and PWM capabilities in minimal package sizes.

Microcontrollers Replacement Considerations

PIC12LF1572-E/MF offers low-voltage operation (1.8V to 3.6V) compared to the standard voltage range. PIC12F1571-E/MF provides reduced program memory and lacks the EUSART peripheral. Verify pinout compatibility and memory constraints before substitution.
