Overview

The 24AA16T-I/OT is a 16Kbit I2C serial EEPROM from Microchip, organized as eight blocks of 256 x 8-bit memory. It operates over a wide voltage range of 1.7V to 5.5V and is housed in a space-saving 5-pin SOT-23 package, making it suitable for low-power and compact embedded designs.

Why Choose This Part

This EEPROM offers high reliability with more than 1 million erase/write cycles and over 200 years of data retention. It features Schmitt Trigger inputs for noise suppression and a 16-byte page write buffer to optimize write timing, all within a tiny SOT-23 footprint.

Applications

Configuration Storage
Storing calibration data, user preferences, and device settings in consumer electronics.
Asset Tracking
Holding serial numbers, MAC addresses, and identification data in industrial modules.
Battery-Powered Devices
Low-power operation with 1uA standby current makes it ideal for wearables and remote sensors.
Data Logging
Recording error logs or event history in space-constrained IoT nodes.

Getting Started

To interface with this device, connect the SCL and SDA lines to an I2C bus with appropriate pull-up resistors. Ensure the VDD remains between 1.7V and 5.5V and utilize the hardware write-protect pin to prevent accidental data corruption during power-up cycles.
