Maxim Integrated DS1961S-F5+ Secure Memory iButton

The DS1961S-F5+ from Maxim Integrated is a robust, secure memory iButton that offers an ideal solution for data storage and authentication applications. This high-security cryptographic iButton device provides 1024 bits of EEPROM memory, which includes a 512-bit user area and a 512-bit register area for control and security functions. The user memory can be accessed with a user-defined 64-bit password, ensuring that sensitive data remains protected from unauthorized access.

One of the key features of the DS1961S-F5+ is its implementation of the SHA-1 (Secure Hash Algorithm) for generating a 160-bit Message Authentication Code (MAC). This feature enables the iButton to perform challenge and response authentication, which is crucial for verifying the authenticity of the device and its stored data. The DS1961S-F5+ performs all SHA functions internally to prevent sensitive data from being exposed to the external environment, adding an extra layer of security.

Designed for operation over a wide temperature range (-40°C to +85°C), the DS1961S-F5+ is encased in a durable stainless steel can, which provides a rugged solution that can withstand harsh environments. This makes it suitable for a variety of applications, including access control, asset tracking, and secure data storage.

The iButton's unique serial number is laser-etched on its surface, providing a tamper-proof and non-duplicable identity. This feature is particularly useful for preventing counterfeiting and ensuring traceability throughout the product's lifecycle. The DS1961S-F5+ communicates through the 1-Wire protocol, which allows for easy integration with a microcontroller or computer through a single data line plus ground reference.

Overall, the DS1961S-F5+ is a powerful and versatile security device that offers a mix of data protection, authentication, and durability, making it an excellent choice for businesses and organizations that require secure and reliable data storage solutions.
