Overview

The PIC12F675 is a versatile 8-bit CMOS microcontroller featuring a 4-channel 10-bit Analog-to-Digital converter and a single comparator in a compact 8-pin package. It operates at speeds up to 20MHz and includes 1.75KB of Flash memory and 128 bytes of EEPROM, making it a staple for simple analog-to-digital control tasks in space-constrained designs.

Why Choose This Part

This MCU offers a highly integrated mix of analog peripherals and non-volatile EEPROM memory in a minimal 8-pin footprint. It is valued by engineers for its low power consumption, internal oscillator options, and 8-level hardware stack which simplifies basic firmware development.

Applications

Analog Sensor Interface
Utilizing the 4-channel 10-bit ADC to digitize signals from temperature sensors, potentiometers, or light-dependent resistors.
Housekeeping and Power Sequencing
Managing power-up sequences and monitoring system rails using the internal comparator and low-power sleep modes.
Small Form Factor Logic Replacement
Replacing multiple discrete logic gates or timers in designs where PCB real estate is at a premium.
Battery-Operated Handhelds
Leveraging typical sleep currents as low as 1nA and low-power POR to extend battery life in intermittent-use devices.
