24AA02E48T-I/OT - 2Kbit I2C EEPROM Memory IC | 400kHz SOT-23-5 Package

The 24AA02E48T-I/OT from Microchip Technology Inc. is a compact and low-power 2-Kbit (256x8) serial EEPROM with an integrated EUI-48 (MAC) address, making it ideal for applications requiring globally unique identification and non-volatile data storage. Organized as two blocks of 128x8 bits, this EEPROM operates via a Two-Wire (I2C-compatible) serial interface, supporting up to 400 kHz clock speed for fast and efficient communication. The device operates with a low voltage range from 1.7 V to 5.5 V, ensuring excellent performance across low-power embedded designs. With a page write capability for up to 16 bytes, low standby current, and robust data retention, the 24AA02E48T-I/OT is widely used in IoT devices, network equipment, and industrial applications that require reliable and unique hardware identification.
