DS28E15Q+U Typical application Circuitry

DS28E15Q U

The DS28E15Q+U is a secure EEPROM with SHA-256 authentication, similar to the DS28E15Q+T, designed for applications requiring secure data storage and cryptographic authentication.

Functionality: This chip provides cryptographic authentication using the SHA-256 hash algorithm, ensuring data integrity and security. It features a 512-bit user-programmable EEPROM for secure data storage.

Application Scenarios: The DS28E15Q+U is used in secure authentication systems, anti-counterfeiting solutions, and secure data storage applications in various industries, including consumer electronics, healthcare, and industrial control.

Parameter Characteristics: The chip operates over a voltage range of 1.8V to 5.5V and uses a 1-Wire interface for communication. It has a 512-bit user EEPROM with write protection capabilities.

Circuit Design for Secure Authentication in Consumer Electronics:

1. Power Connection: Connect the VDD pin of the DS28E15Q+U to a 3.3V power supply and the GND pin to the system ground.

2. 1-Wire Communication: Connect the DQ pin of the DS28E15Q+U to a digital input/output pin on the microcontroller. Use a 4.7kΩ pull-up resistor between the DQ pin and VDD.

3. Data Transfer: Utilize the microcontroller to send and receive commands and data to and from the DS28E15Q+U through the 1-Wire interface, adhering to the chip's communication protocol for secure operations.

4. EEPROM Programming: Store a unique secret key in the DS28E15Q+U's EEPROM and set up write protection to safeguard the stored data from unauthorized access.

Design Considerations:

- Stable Power Supply: Ensure that the power supply is stable to avoid data corruption and authentication failures.

- Correct Pull-up Resistor Value: Choose the right pull-up resistor value for the 1-Wire interface to guarantee reliable communication.

- Secret Key Security: Securely store and protect the secret key to prevent unauthorized access to the chip's secure data.

- EMI Minimization: Design the circuit to minimize electromagnetic interference, which could disrupt communication on the 1-Wire interface.

By following this circuit design, a secure authentication system can be implemented in consumer electronics using the DS28E15Q+U chip, leveraging its cryptographic authentication capabilities.
