Introduction of DS28C36Q+U

The DS28C36Q+U is a specialized integrated circuit (IC) used for authentication and protection of electronic products and systems. It contains a 2Kb EEPROM, 4Kb OTP ROM and 4Kb of cryptographic algorithms, along with built-in cryptographic acceleration logic.

Application Field of DS28C36Q+U

The DS28C36Q+U can be used to detect unauthorized access, counterfeiting and tampering with products, embedded systems and other critical assets. It can be applied in a variety of industries and applications, including access control, smart cards, payment systems, automotive, medical, industrial and military products.

For example, in the automotive industry, when building a high-end car or luxury SUV, the DS28C36Q+U can be used to add a layer of security to the system, protecting it from theft and tampering. In payment systems, the chip can add an extra layer of security, ensuring that payments are verified and executed properly, and that all financial data remains secure.

Working Principle of DS28C36Q+U

The DS28C36Q+U chip is designed to operate on a 3.3V power supply and can be used with the Atmel Secure Reversible Power-on (ASRP) controller and EEPROM memory. This allows the device to easily integrate with existing systems.

The device features a regular bus interface and a special single-wire design, making it ideal for applications that require secure communication. Additionally, the chips support both SHA-256 and ECDSA-P521 algorithm. This ensures that data is authenticated and strong encryption is used for secure transactions.

In addition, this chip has many unique features to detect tampering and unauthorized access. It has an on-chip tamper detection circuit which can detect physical tampering such as voltage or clock manipulation. It also has a one-time-programmable (OTP) section, which can be used to store sensitive information that is only accessible to the chip.

The DS28C36Q+U also includes a secure challenge and response protocol, which authenticates communication between devices and ensures the integrity of data exchange. All the data is transmitted in an encrypted format and is further secured by the DS28C36Q+U\'s crypto engine.

Conclusion

The DS28C36Q+U chip is a specialized integrated circuit designed to provide strong security and encryption for embedded systems and other critical assets. It has a built-in EEPROM and several cryptographic engines and algorithms, making it ideal for applications that require secure communication. Additionally, it has a tamper detection circuit and support for OTP security. All these features make the DS28C36Q+U an ideal choice for secure authentication and protection of electronic products and systems.
