Maxim Integrated DS28C36Q+T DeepCover Secure Authenticator

The DS28C36Q+T is a highly secure, low-power authenticator from Maxim Integrated that provides robust protection against unauthorized access and counterfeit products. This DeepCover® secure authenticator incorporates advanced cryptographic algorithms and a unique chip ID to ensure the integrity and security of both the device and the data it contains.

At the heart of the DS28C36Q+T is a FIPS/NIST compliant True Random Number Generator (TRNG), which is essential for creating secure cryptographic keys. The device also features a SHA-256 hash engine, which is instrumental in verifying data signatures and ensuring that the information has not been tampered with. The public/private key asymmetric ECDSA (Elliptic Curve Digital Signature Algorithm) is used for secure challenge and response authentication, providing a high level of security for applications such as IoT devices, medical sensors, and other sensitive electronic systems.

The DS28C36Q+T also includes a set of user-programmable EEPROM memory blocks. These blocks can be used to store secure data such as cryptographic keys, certificates, or device configuration settings. The EEPROM is write-protected to prevent unauthorized modifications, and a secure monotonic counter is provided to prevent replay attacks.

For ease of integration, the DS28C36Q+T operates over a wide voltage range and communicates via a standard I2C interface, making it compatible with a broad range of microcontrollers and systems. Its compact form factor is available in a 6-pin TDFN package, which is ideal for space-constrained applications.

Key features of the DS28C36Q+T include:

• FIPS/NIST compliant True Random Number Generator (TRNG)
• SHA-256 hash engine for secure data verification
• ECDSA public/private key generation for secure challenge and response authentication
• User-programmable and write-protected EEPROM
