Overview

The 24LC08B is an 8-Kbit I2C serial EEPROM designed for low-power applications with a wide voltage range of 2.5V to 5.5V. It is organized as four blocks of 256 x 8-bit memory and supports a 400 kHz clock frequency for reliable data retrieval and storage. This AEC-Q100 qualified device is optimized for non-volatile storage in automotive and industrial environments.

Why Choose This Part

The device features Schmitt Trigger inputs for noise suppression and output slope control to minimize ground bounce, making it ideal for noisy electrical environments. It offers high reliability with over 1 million erase/write cycles and more than 200 years of data retention. With a standby current of only 1 uA, it is highly efficient for battery-powered designs.

Applications

Configuration Storage
Retaining calibration constants and user settings in embedded systems even after power loss.
Data Logging
Recording system events or sensor data using the 16-byte page write buffer for efficient storage.
ID and Serialization
Storing unique hardware identifiers and manufacturing data in industrial equipment.
Automotive Systems
Utilizing AEC-Q100 qualification for rugged non-volatile memory requirements in vehicle electronics.

Getting Started

To interface with the 24LC08B, connect the SCL and SDA lines to a microcontroller I2C peripheral using pull-up resistors. Use the hardware write-protect (WP) pin to prevent accidental data overwrites during power cycles. Developers can utilize standard I2C libraries to perform byte writes or efficient 16-byte page writes.
