Microchip Technology 24AA02UID-I/SN EEPROM

The 24AA02UID-I/SN is a 2Kb I2C™ compatible Serial EEPROM with a built-in 32-bit serial number from Microchip Technology. This device is specifically designed for applications requiring unique ID values at a chip level, providing a cost-effective solution for device serialization and data storage.

Featuring a standard 8-pin SOIC (SN) package, the 24AA02UID-I/SN is versatile and suitable for a broad range of applications. It operates across a wide voltage range of 1.7V to 5.5V and supports a temperature range from -40°C to +85°C, making it ideal for industrial, automotive, and consumer electronics.

The EEPROM is organized as 256 x 8 bits, which allows for efficient data management and storage solutions. The inclusion of a pre-programmed, globally unique ID makes it an excellent choice for applications such as accessory authentication, PCB identification, and network node identification without the need for any additional external components.

Communication with the 24AA02UID-I/SN is facilitated through a fast I2C interface with speeds up to 1 MHz, ensuring high-speed data transfer and compatibility with most microcontrollers. Additionally, the device supports a write-protect feature, which prevents accidental data overwrites and enhances data integrity.

Key features of the Microchip 24AA02UID-I/SN include:

• 2 Kbit (256 x 8) Serial Electrically Erasable PROM
• Pre-programmed 32-bit serial number
• Operating voltage range of 1.7V to 5.5V
