Maxim Integrated DS28E07P+T EEPROM Description

The Maxim Integrated DS28E07P+T is a robust, low-cost, and high-performance 1-Wire EEPROM (Electrically Erasable Programmable Read-Only Memory) designed to provide secure and reliable data storage in a diverse range of applications. This device is particularly well-suited for environments where a small data storage module is required, and it can be easily integrated into various systems due to its simple 1-Wire interface, which minimizes the number of required I/O lines.

With a memory capacity of 1024 bits (128 bytes), the DS28E07P+T allows for the storage of vital data such as calibration constants, user preferences, product identification, and usage data. The EEPROM is organized as four memory pages of 256 bits each, providing flexibility in data management and access.

The device operates over a wide voltage range of 2.8V to 5.25V, making it versatile for both 3V and 5V systems. Its operating temperature range of -40°C to +85°C ensures reliable performance under varying environmental conditions, making it suitable for industrial and commercial applications.

One of the key features of the DS28E07P+T is its unique 64-bit ROM identification code, which is factory-lasered into each chip. This code ensures that each device is uniquely identifiable, providing a robust solution for anti-counterfeiting measures and secure device authentication. The 1-Wire interface also supports multi-drop configurations, allowing multiple devices to be connected on the same bus for efficient data communication and system expansion.

Additionally, the DS28E07P+T incorporates write cycle counters for each page, which can be used to monitor the number of write operations and help predict the end of the device's useful life. This feature is particularly useful in systems where data integrity over time is critical.

The compact package of the DS28E07P+T makes it an ideal choice for space-constrained applications. The device is available in a TDFN (Thin Dual Flat No-lead) package, which provides a small footprint while ensuring robust mechanical and thermal characteristics.

In summary, the Maxim Integrated DS28E07P+T is a highly reliable and secure EEPROM solution that offers a convenient and efficient way to store and manage data in a wide range of applications.
