The DS28E07-100+T is a member of the DS28E07 family of one-wire devices from Maxim Integrated. It is designed to simplify the integration of secure authentication in low-cost and cost-effective embedded system applications. The device is a one-wireⓇ, low-power, and secure authentication device that uses asymmetric cryptography to prevent counterfeiting and the introduction of bogus parts into products. The device can also be used to help maintain the integrity of products throughout the design, manufacturing, and distribution process.

The DS28E07-100+T offers an ideal solution for applications that require a secure, highly integrated, and reliable solution. It features 128-bit symmetric key cryptographic operation with random number generation. The device utilizes Maxim\'s secure Secure ID secret number generation algorithm to generate a unique random number on every power-up. This random number can be used to secure communications, store secure configuration data, and prevent counterfeiting of goods.

The DS28E07-100+T can be used for authentication, encryption, secure booting, secure firmware upgrades, secure remote access to servers, secure cloud connections, and secure remote access to devices. The device is designed to be used in a wide range of industrial and consumer applications, including automotive, medical, industrial, home automation, and consumer electronics. The device can also be used for encryption and authentication in enterprise systems, such as secure printing systems, secure retail systems, and secure cyber-physical systems.

The working principle of the DS28E07-100+T revolves around the one-wire interface. This single-wire protocol allows the device to communicate with a master, communicating data and commands. The single-wire protocol requires communication to be performed by exchanging a sequence of data packets. The packet exchange between the master and the DS28E07-100+T requires the master to send and receive data bits. In response, the DS28E07-100+T can respond with data bits.

The DS28E07-100+T also features an on-board EEPROM for secure storage of private key information, such as device IDs and cryptographic keys. The on-board EEPROM can be used to securely store and retrieve cryptographic keys, device IDs, configuration settings, and other private data. The device also provides a secure read-only mechanism to ensure that once a key is stored in the EEPROM, it cannot be read by any unauthorized entity. The on-board EEPROM can also be used to store configuration settings and firmware.

The DS28E07-100+T also includes a 16-bit CRC (cyclic redundancy check) for error detection. This CRC is used to detect device command errors, as well as any communication errors that may occur during transmission. In addition, the device also incorporates an automatic reset feature to help ensure reliable operation and protect against power surges.

The DS28E07-100+T is a powerful, secure, and cost effective solution for authentication, encryption, secure booting, secure firmware upgrades, secure access to servers, and secure access to devices. The device is an ideal solution for applications that require a secure, highly integrated, and reliable authentication solution. The device’s on-board EEPROM ensures secure storage of data and configuration settings, while its one-wire interface simplifies communications.
