Maxim Integrated DS28E04S-100+T: High-Capacity 1-Wire EEPROM

The DS28E04S-100+T from Maxim Integrated is a versatile and robust 4Kb 1-Wire EEPROM designed for applications where easy and secure data storage is paramount. This memory device combines a large user-programmable EEPROM with a unique, factory-lasered and tested 64-bit registration number, which ensures a unique identity for each device. The DS28E04S-100+T is ideal for product authentication, data storage, and calibration applications.

With its 1-Wire interface, the DS28E04S-100+T allows for a simple two-point contact for both power and communication, minimizing the wiring complexity and making it perfect for space-constrained environments. This interface also enables the device to derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.

The EEPROM is organized as 512 pages, each containing 8 bytes of data. This organization provides a high degree of flexibility, allowing users to store and access data in a way that best suits their needs. The device also features a write cycle counter for each page, which can be used to monitor the health and usage of the memory, ensuring data integrity over the product's lifespan.

For security, the DS28E04S-100+T offers a number of features. Each device has a unique 64-bit serial number, which can be used to protect the access to the memory and ensure that only authorized devices can communicate with it. Additionally, the device provides a full 512-byte scratchpad with strict read/write protocols to ensure data integrity when writing to the memory array.

The DS28E04S-100+T is available in a compact SMT package, specifically the TSOC-6, which is suitable for automated assembly processes, and its temperature range of -40°C to +85°C allows for operation in a wide range of environments. Whether it's for tracking system data, managing customer configurations, or securing communication between devices, the DS28E04S-100+T offers a reliable and flexible solution for your data storage needs.

Maxim Integrated's commitment to quality and reliability is evident in the DS28E04S-100+T, making it a smart choice for designers looking for a high-capacity, secure EEPROM with a minimal footprint.
