DS2505P+T&R is a multifunctional memory device with non-volatile eeprom and authentication with millisecond response time. This memory device is made up of 64-byte memory pages for minimal programming time, 256-byte write-once version of some code-protection ICs and 4K bits of OTP (One Time Program). It features a very low power consumption of 2.6μA from the self-contained voltage regulator and a 400kHz I2C interface for two-wire communication.

The application of a DS2505P+T&R is most commonly seen in automotive use in terms of immobilizers. Automotive immobilizers commonly utilize the E2Prom memory device inside them to store authentication data as well as various other data. Since these products require high security, the DS2505P+T&R is an ideal solution. In addition, the device can also be used in various other areas, such as industrial applications and asset tracking.

The working principle of the DS2505P+T&R is easy to understand. It utilizes the I2C interface in order to communicate with a microcontroller or other devices. The I2C interface is also responsible for inputting and outputting data from the device. The data is stored in the non-volatile E2Prom memory, which is not affected by sudden power outages or other external influences. In addition, the device utilizes an authentication protocol called T&R in order to ensure that the data is protected.

The T&R protocol stands for Time-out and Randomization algorithm, and it cryptographically binds the user to the device. This protocol requires that in order to authenticate data, the user must input a randomly generated token, with each token being valid for only a specific period of time. This provides an additional layer of security for the data stored in the device, making it more difficult for any unauthorized access. Once the authentication is successful, the user can then access the device data.

The DS2505P+T&R memory device is a highly secure and efficient device that can be used in a variety of different applications. It is ideal for automotive immobilizers, asset tracking, and other industrial applications where security is a must. With its I2C interface, low power consumption, and the added benefit of the time-out and randomization protocol, the DS2505P+T&R provides an unparalleled level of security.
