DS28E15Q+T Typical application Circuitry

DS28E15Q+T

A safe EEPROM with SHA-256 authentication is the DS28E15Q+T. It's designed for applications requiring secure data storage and cryptographic authentication, such as access control, secure communication, and counterfeit protection.

Functionality: The DS28E15Q+T uses a SHA-256 hash algorithm to provide cryptographic authentication, ensuring data integrity and security. It has a 512-bit user-programmable EEPROM for storing secure data.

Application Scenarios: This chip is commonly used in applications like secure authentication for peripherals, anti-counterfeiting measures in consumer products, and secure data storage in medical devices.

Parameter Characteristics: The DS28E15Q+T operates over a wide voltage range (1.8V to 5.5V), has a 1-Wire interface for communication, and features a 512-bit user EEPROM with write protection.

Access Control Circuit Design:

1. Power Supply: Attach the DS28E15Q+T's GND pin to the ground and its VDD pin to a 3.3V power source.

2. 1-Wire Interface: Connect the DQ pin of the DS28E15Q+T to a digital I/O pin on the microcontroller. Use a 4.7kΩ pull-up resistor between the DQ pin and VDD.

3. Data Communication: Use the microcontroller to send commands and data to the DS28E15Q+T through the 1-Wire interface, following the chip's communication protocol for authentication and EEPROM access.

4. Security Configuration: Program the DS28E15Q+T with a unique secret key and configure the EEPROM write protection settings to secure the stored data.

Design Considerations:

- Power Supply Stability: Ensure a stable power supply to prevent data corruption and authentication errors.

- Resistor Pull-up: For the 1-Wire interface, choose a suitable pull-up resistor value to provide dependable communication.

- Secret Key Protection: Protect the secret key from unauthorized access and ensure it's securely programmed into the chip.

- Electromagnetic Interference (EMI): Minimize EMI in the circuit design to prevent communication errors on the 1-Wire interface.

This circuit design provides a secure authentication system for access control, utilizing the cryptographic capabilities of the DS28E15Q+T chip.
