Working Principle

The DS28DG02E-3C+T is designed with a fault-tolerant architecture that allows it to work reliably, as well as securely. It follows the 1-Wire protocol, where each device is assigned a unique ID, making it virtually impossible to counterfeit or clone. The 1-Wire protocol also ensures maximum protection from unwanted access through the use of CRC checksum, making it extremely resistant to interference.

Data can be transferred serially using the I2C interface and it supports both 1-Wire and I2C, providing flexibility for different applications. It also supports write-once, read-only and sequential read operations, allowing the user to store and access data safely and reliably. Finally, the DS28DG02E-3C+T incorporates AES-128 encryption, providing a higher level of security.

In addition to the 1-Wire and I2C interfaces, the DS28DG02E-3C+T also features a watchdog timer and various reset options, providing an extra layer of safety for critical applications. The DS28DG02E-3C+T also features adaptive flow control and data-rate detection alongside the high environmental immunity, making it an ideal choice for applications where reliability and security are crucial.

Conclusion

The DS28DG02E-3C+T is an excellent choice for applications needing a reliable and secure memory solution. It is designed for use in a variety of demanding applications, including medical, financial, automotive, military and avionics. It features high security through a combination of 1-wire protocol, CRC checksum, AES-128 encryption, watchdog timer and adaptive flow control. The DS28DG02E-3C+T is an excellent solution for those requiring a secure and reliable storage device.
