Hi Feng,

Yes, all TMP117 devices will have a unique ID. The unique ID is located in all of the general-purpose EEPROM locations and is used for NIST traceability.

Best regards,

Sydney

Hi Sydney,

Good to hear that.

So customer can get the ID information by I2C interface, Right ? Thanks.

Hi Feng,

The customer will be able to read the ID numbers via I2C.

The unique ID allows TI to link a device to its individual production test record, however this record is not available to the public/customers. Therefore, the customer can obtain the ID numbers through I2C, but we cannot provide information on what the ID numbers mean.

Please see this related E2E post about the TMP116 for more information: TMP116: Nist traceability and Unique ID ? - Sensors forum - Sensors - TI E2E support forums

Best regards,

Sydney
