Microchip Technology's 24AA02UID-I/P EEPROM

The 24AA02UID-I/P is a 2 Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) device from Microchip Technology, designed for flexible data storage in a wide range of applications. This integrated circuit (IC) is particularly suitable for those applications that require a serial EEPROM with an embedded unique ID.

Featuring a standard I<sup>2C-compatible serial interface, the 24AA02UID-I/P allows for easy integration into existing designs and supports a bidirectional data transfer protocol. Its 256 x 8 (2 Kbit) memory size is organized in 8-byte pages, providing ample space for storing configuration settings, calibration data, or small application logs.

One of the unique features of the 24AA02UID-I/P is its pre-programmed, globally unique 48-bit serial number, which is stored in a read-only area. This unique ID can be used for network node identification, access control, or any application where a distinct serial number is needed to ensure the authenticity of the device or the data stored within.

The device operates across a voltage range of 1.7V to 5.5V, making it compatible with most low-power and standard logic level systems. Its low power consumption and wide operating temperature range from -40°C to +85°C make it an excellent choice for industrial and consumer applications that require a reliable non-volatile memory solution in challenging environments.

Encased in a PDIP (Plastic Dual In-line Package) format, the 24AA02UID-I/P is designed for through-hole mounting, which is ideal for prototyping and applications where manual assembly or adjustments may be necessary. The product's long-term data retention, coupled with a high endurance of one million write cycles, ensures the reliability and longevity of the data storage.

In summary, the Microchip Technology 24AA02UID-I/P EEPROM provides a compact, reliable, and cost-effective data storage solution with the added benefit of a unique identifier for enhanced security and device authentication purposes.
