Overview

The 24AA128-I/SN is a 128 Kbit (16,384 x 8) Serial EEPROM capable of operating across a wide voltage range of 1.7V to 5.5V. It utilizes a 2-wire I2C compatible serial interface and features a 64-byte page write buffer to optimize data throughput.

Why Choose This Part

This device offers excellent reliability with over 200 years of data retention and robust ESD protection exceeding 4,000V. Its cascadable architecture allows up to eight devices on the same I2C bus, while the Schmitt Trigger inputs provide superior noise suppression for industrial environments.

Applications

Configuration Storage
Storing calibration data, user preferences, and network settings in industrial and consumer devices.
Data Logging
Recording system events or sensor readings over time with high endurance requirements up to 1 million cycles.
ID and Asset Tracking
Storing serial numbers and hardware revision information in modular electronic assemblies.

Getting Started

To interface with this EEPROM, connect the SDA and SCL lines to your microcontroller's I2C bus with appropriate pull-up resistors and configure the A0, A1, and A2 pins for the desired bus address. Ensure the WP (Write-Protect) pin is tied to GND for normal operation or VCC to protect the memory array from accidental writes.
