MSP430FR2433: Integrated Temperature sensor accuracy in TLV

Hi Uchikoshi, There is no TLV on temperature sensor and no temperature sensor accuracy parameter in MSP430FR2433 device.

Hi Xiaodong,

Yes, we understand there is no spec on the datasheet so I am asking it.

What is the worst data, 30+-3 degree or 30+-5 degree, etc?

Regards,

Uchikoshi

Hi Uchikoshi, Our test on temperature sensor accuracy consistence is very limited on MSP430FR2433. So far, we can't guarantee the accuracy per device based on our limited test data.

Hi Xiaodong,

You do not need to guarantee it. For the reference, we want to know these data to decide to use calibration data in TLV or execute single-point calibration method.

Hi Uchikoshi, the temperature change trend can be detected use calibration data in TLV. for temperature value measurement, I think 2-points (30C and 85C) on-board calibration is needed. Thanks!

Hi Xiaodong,

Thank you for your reply and I am sorry again that your answer is not to my question. When TI calibrate it, if the room temperature is varied +- 3 degree, TLV data has a chance to have +-3 degree variation. As such, we want to know how TLV data vary.

Hi Xiaodong,

Is there any update?
