AM5728: Internal temperature sensors

Nomo

Part Number: AM5728

Hello,

My customers want to use the CTRL_CORE_TEMP_SENSOR_MPU and CTRL_CORE_TEMP_SENSOR_GPU register to know the temperature and alert for the threshold.
Could you tell me the maximum error of these register?

Best Regards,
Nomo

Nomo,

Section 18.4.6.2.3 of the TRM contains the following statement:

The values of the five low and high TSHUT thresholds are fix and can be neither overridden nor read by
software. The value for the high TSHUT threshold is 123°C (assuming ±2°C temperature sensor accuracy)
and for the low TSHUT threshold it is 105°C.

Therefore, the temperature sensor accuracy is expected to be about ±2°C.
