Description

The 24AA025UIDT-I/OT is a 256-bit (32 x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) device from Microchip Technology. It features a 2-wire I²C interface, allowing for easy communication with microcontrollers. This EEPROM operates at a voltage range of 1.7V to 5.5V, making it suitable for various low-power applications.
The device is notable for its fast write cycle time, typically around 5 ms, and supports multiple device addressing, enabling connection of up to eight devices on the same I²C bus. It includes features like write protection and an automatic page write capability, which simplifies data storage operations. The 24AA025UIDT-I/OT is often used in applications requiring non-volatile memory, such as data logging, configuration storage, and product identification.
The suffixes in the part number indicate specific features, such as temperature range and packaging type, with "I" suggesting industrial temperature range and "OT" implying the device is offered in a lead-free package.

Features

The 24AA025UIDT-I/OT is a 2-kilobit (256 x 8) I2C compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Microchip Technology. Key features include:
