Maxim Integrated DS28E01P-100+T Secure Authentication Chip

The DS28E01P-100+T from Maxim Integrated is a robust, secure authentication chip that provides a cost-effective solution for safeguarding communication between devices. This chip is designed to ensure that only authorized accessories and peripherals can access the host system, thus preventing counterfeiting and unauthorized usage.

At the heart of the DS28E01P-100+T is a SHA-1 engine that combines a secret stored value with incoming challenge data and a 512-bit EEPROM registration number to produce a 160-bit Message Authentication Code (MAC). This MAC is unique to each device and cannot be duplicated, providing a strong line of defense against security breaches.

The chip operates over a wide voltage range of 2.8V to 5.25V, making it versatile for various applications. It communicates over a single-contact 1-Wire interface, which minimizes the number of necessary connections and simplifies integration into existing systems. This interface also allows for the device to be powered parasitically from the data line, further reducing the system's power requirements.

Additional features of the DS28E01P-100+T include a 1024-bit EEPROM organized as four pages of 256 bits, with the first 128 bits of each page available for user data storage. This storage is ideal for storing sensitive data, as it is protected by the SHA-1 algorithm to ensure that the data integrity is maintained.

The device's small footprint is encapsulated in a 6-pin TSOC package, making it suitable for applications where space is at a premium. The DS28E01P-100+T is also available in tape and reel form, denoted by the 'T' suffix, facilitating its use in high-volume production environments.

Whether it's for securing medical devices, consumable goods, or peripheral authentication, the Maxim Integrated DS28E01P-100+T provides a high-security, low-cost solution for protecting your products and brand integrity.

For designers and engineers looking for a reliable security component, the DS28E01P-100+T offers ease of implementation and the peace of mind that comes with using a product from Maxim Integrated, a trusted leader in integrated circuits.
