DS28E10R+T

DS28E10R+T is a non-volatile memory (NVM) component combined with an integrated 1-Wire master-slave authenticator and a temperature sensor. This component is especially suitable for applications where device authentication is required. The component operates as a slave device on a 1-Wire bus, where the master device can initiate authentication or other device-specific operations.

Application Field

The combination of TEMP and authenticator in a single component makes DS28E10R+T an ideal choice for a range of wearable, automotive, and IoT applications. This component can be used for condition-based monitoring and control, where device authentication and temperature measurement are required.

In healthcare applications, the component can monitor environment and ensure integrity of the data stored. It is also suitable for asset tracking, which needs to ensure secure transmission of data. In smart building applications, DS28E10R+T can be used to monitor the environment and ensure secure access points.

Working Principle

The DS28E10R+T provides a secure authentication protocol that can be used by the master device to authenticate the slave device. The protocol works by providing a challenge-response mechanism, where the master device sends a challenge, and the slave device returns a response that is compared with the master device\'s expected response. The response is based on the authentication key stored in the component.

The component has a built-in temperature sensor, which can measure temperature with a resolution of 0.0625°C. It has two alert levels, which can be set through the 1-Wire interface. The component can also provide a time history of up to 24 temperature readings, which can be used to monitor and provide statistical data.
