Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DS28E16Q Secure Authenticator combines FIPS202-compliant Secure Hash Algorithm (SHA-3) polling and response authentication with secure EEPROM.

The DS28E16Q device provides a core set of cryptographic tools including a SHA-3 engine, 256-bit secure EEPROM, decrementing counter, and a unique 64-bit ROM identification number (ROM ID). The unique ROM ID is used as a basic input parameter for cryptographic operations and as an electronic serial number in applications. The devices communicate over a single-contact 1-Wire® bus. The communication is based on the 1-Wire protocol and the ROM ID serves as the node address in a multi-device 1-Wire network.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
