Overview

The PIC12F629 is a cost-effective 8-bit CMOS microcontroller based on the PIC architecture, featuring a compact 8-pin footprint. It integrates 1.75KB of Flash memory, 128 bytes of EEPROM, and an internal oscillator, making it ideal for simple control logic in space-constrained designs. With low power consumption and a wide operating voltage from 2V to 5.5V, it serves as a reliable building block for basic embedded systems.

Why Choose This Part

This MCU offers a versatile 8-level deep hardware stack and an internal oscillator that eliminates the need for external timing components. It features high-endurance Flash and EEPROM cells suitable for non-volatile parameter storage, combined with a power-saving sleep mode for high efficiency.

Applications

State Machine Control
Implementing simple logical sequences for consumer appliances or industrial timers where a full-sized MCU is unnecessary.
I/O Expansion
Managing simple button debouncing or LED patterns to offload basic tasks from a primary system processor.
Battery-Powered Sensors
Utilizing the 0.99uA sleep current and 2.0V minimum VDD for long-term monitoring in remote hardware.
Signal Conditioning
Performing basic pulse-width measurement or level detection using the integrated timer and interrupt-on-change pins.
