Microchip Technology's 24AA256UIDT-I/SN EEPROM

The 24AA256UIDT-I/SN from Microchip Technology is a high-performance, 256-Kilobit EEPROM (Electrically Erasable Programmable Read-Only Memory) with a unique, pre-programmed 32-bit serial number. It is part of Microchip's extensive range of memory products designed for data storage and retrieval in a wide array of applications. This particular model comes in a compact 8-pin SOIC (Small Outline Integrated Circuit) package, making it suitable for space-constrained applications.

One of the key features of the 24AA256UIDT-I/SN is its I²C-compatible (Inter-Integrated Circuit) interface, which supports standard, fast, and high-speed modes for versatile communication options. The device operates over a single supply voltage range of 1.7V to 5.5V, which allows it to be used in both 3.3V and 5V systems. This flexibility makes it an ideal choice for a variety of consumer and industrial applications.

The EEPROM provides a substantial amount of non-volatile memory, meaning that the data stored within is retained even when the power is turned off. This feature is essential for applications that require data persistence, such as configuration settings, calibration data, or device identity storage. The pre-programmed unique serial number is an added benefit that can be used for inventory control, device authentication, or network node identification, enhancing the security and traceability of the final product.

Furthermore, the 24AA256UIDT-I/SN supports a maximum write cycle time of 5 ms, allowing for efficient data management and quick updates to stored information. It is rated for industrial temperature range (-40°C to +85°C), ensuring reliable operation under extreme conditions. Additionally, the EEPROM is designed with write protect features to prevent inadvertent data overwrites, which is crucial for maintaining data integrity.

In summary, the 24AA256UIDT-I/SN EEPROM from Microchip Technology is a robust and versatile memory solution that offers a significant amount of storage space, a convenient serial interface, and a unique identification number. It is designed to meet the requirements of a broad range of applications that necessitate reliable and secure data storage.
