Overview

The 24AA01T-I/OT is a 1Kbit I2C serial EEPROM organized as 128 bytes of 8 bits each. This low-voltage device operates from 1.7V to 5.5V and features a small SOT-23-5 package, making it ideal for compact designs requiring non-volatile storage. It supports a 400 kHz clock frequency and includes hardware write-protection and Schmitt trigger inputs for noise suppression.

Why Choose This Part

This component offers high reliability with over 1 million erase/write cycles and a data retention period exceeding 200 years. Its low-power CMOS technology consumes only 1uA in standby mode, and the AEC-Q100 qualification ensures suitability for harsh automotive environments.

Applications

Configuration Storage
Storing calibration data and system configuration parameters in industrial and automotive applications.
Device Identification
Providing unique serial numbers or MAC addresses for networked hardware modules.
Usage Tracking
Recording error logs, power cycles, or maintenance intervals in space-constrained consumer electronics.

Getting Started

To interface with this EEPROM, connect the SCL and SDA lines to a microcontroller's I2C peripheral with appropriate pull-up resistors. Use the 8-byte page write buffer to optimize write times, ensuring that the self-timed write cycle completes before subsequent operations. Development is supported by standard I2C libraries across platforms like Microchip MPLAB X or Arduino.
