Overview

The PIC12F1822-I/SN is a compact 8-bit microcontroller featuring Microchip's eXtreme Low Power (XLP) technology in a space-saving 8-pin SOIC package. It operates at speeds up to 32MHz and includes 3.5KB of Flash memory along with a dedicated 256-byte EEPROM for non-volatile data storage. This MCU is designed for cost-sensitive, power-constrained applications requiring essential digital and analog peripherals.

Why Choose This Part

The device offers a high level of integration for its size, including a precision internal oscillator and multiple communication interfaces like I2C, SPI, and UART. Its 25mA source/sink capability per I/O allows for direct driving of LEDs or small relays without external transistors. Engineers benefit from the dedicated 256-byte EEPROM, which simplifies the storage of calibration data and configuration parameters.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology and a low-power internal oscillator to maximize battery life in simple environmental monitoring nodes.
Handheld Portable Devices
Ideal for basic user interfaces or control logic in small consumer electronics due to its 1.8V to 5.5V operating range.
Automotive Interior Control
Commonly used for simple LINbus slave nodes such as window controls or lighting modules in vehicle cabins.
System Supervisors
Acts as a low-cost housekeeping controller for power sequencing, reset management, and simple watchdog functions.
