概述

Description

25AA02UIDT-I/OT is a 2-kilobit (256 x 8-bit) serial EEPROM (Electrically Erasable Programmable Read-Only Memory) designed for low-power applications. It utilizes the I²C communication protocol, allowing multiple devices to be connected on a single bus, which is ideal for embedded systems. The 'UIDT' designation indicates that it features a unique ID (UID) capability, enabling each chip to be identified individually in a networked environment.
This EEPROM operates over a voltage range of 1.7V to 5.5V and supports fast data transfer rates, making it suitable for applications such as secure data storage, configuration settings, and calibration data in consumer electronics, automotive systems, and industrial controls. It also includes features like write protection and endurance of up to 1 million write cycles, ensuring reliability and data integrity. The 'I/OT' suffix often denotes specific package options or temperature ratings, making it versatile for various design needs.
