Overview

The PIC12F629-I/SN is a cost-effective 8-bit CMOS microcontroller featuring 1KB of Flash memory and 128 bytes of EEPROM in a compact 8-pin SOIC package. It includes an internal oscillator and basic peripherals like a Watchdog Timer and Power-on Reset, making it an ideal choice for simple control logic in space-constrained designs.

Why Choose This Part

This microcontroller offers a high level of integration for its size, including an internal oscillator that frees up I/O pins for application use. Its extremely low standby current of 1uA and 5us wake-up time from sleep make it highly efficient for battery-operated or intermittent-use applications.

Applications

Simple Logic Replacement
Replacing discrete logic or timer circuits in consumer and industrial devices to reduce component count.
Power Sequencing
Managing power-up and power-down timing for larger system components with its built-in timers and low-power modes.
LED Control
Driving simple lighting effects or status indicators using its 5 I/O pins and internal clock.
Sensor Interfacing
Acting as a local controller for basic sensors where only digital I/O or interrupt-on-change capabilities are required.
