Overview

The Microchip 24LC02B-I/P is a 2-Kbit I2C Serial EEPROM designed for through-hole mounting, making it suitable for prototyping and educational applications. This non-volatile memory solution offers simple integration into microcontroller-based systems using the widely adopted I2C communication interface. Its robust design includes features like noise suppression and ESD protection.

Why Choose This Part

This EEPROM provides reliable non-volatile storage with over 1 Million erase/write cycles and data retention exceeding 200 years. Its wide supply voltage range (2.5V to 5.5V) and industrial temperature rating (-40C to 85C) ensure broad compatibility and robust operation. The 8-pin PDIP package is easy to handle and solder, ideal for educational projects or repairable designs.

Applications

Data Logging
Storing configuration settings, calibration data, or small amounts of sensor data in embedded systems.
System Configuration Storage
Retaining operational parameters for microcontrollers or other ICs that need to power up with specific settings.
Prototyping and Development Boards
Its 8-DIP package simplifies integration into breadboards and perfboards for easy experimentation and learning.
Low-Volume Production
Suitable for products requiring through-hole components where board space is not critically constrained.

Getting Started

To get started with the 24LC02B-I/P, connect it to a microcontroller's I2C bus (SDA and SCL lines) along with VCC and GND. Many microcontroller development environments, such as Arduino IDE or Microchip MPLAB X, provide libraries or code examples for I2C EEPROM communication. A basic circuit with pull-up resistors on the I2C lines is typically all that is required.
