Professional unlock chip DS series DS28E01 DS2431 IC unlock

The DS28E01 produced by MAXIM combines 1024-bit EEPROM with a challenge-response security certification that complies with ISO / IEC110118-3 Secure Hash Algorithm (SHA-1). 1024-bit EEPROM (divided into four pages, 256 bits per page), 64-bit key, a register page, 512-bit SHA-1 engine, and 64-bit ROM serial code are integrated into an MCU. The DS28E01 serially transmits data according to the 1-Wire protocol. The communication rate is 15.3kbps (standard rate mode) or 125kbps (high-speed mode). Only one data line and one return ground line are needed, which saves the controller to the greatest extent. Occupation of I / O ports.
Over the past few decades, the DS28E01 unlock has evolved from a prototype development tool to a flexible solution for consumer and industrial applications. As the complexity of the DS28E01 decryption logic rises from thousands of logic gates to millions of logic gates, the DS28E01 decryption device can accommodate more system-critical functions.
OROD technology designers can choose the DS28E01 to unlock Today. Because the configuration data is stored in the DS28E01 unlock chip, and the chip has a mechanism to prevent the storage data from being read, flash-based solutions provide a relatively secure solution. In addition, unless very sophisticated methods are used to disable the security mechanism, the probability of data corruption is very low.
In order to prevent the DS28E01 decryption system cost from increasing sharply, designers must continue to use DS28E01 chip-based decryption without encryption. But they must find a way to protect their IP and keep the cost of security measures to the lowest possible level without having a significant impact on the production process. It is imperative to design that the hardware circuit for DS28E01 decryption security protection is installed in the space allowed by the circuit board without increasing the overall power consumption. And, the impact of security on FPGA resources must be as small as possible.
