10.2.3 NVM Temperature Log Row

The NVM Temperature Log Row contains calibration data that are determined and written during production test and cannot be written.

These calibration values are required for calculating the temperature from measuring the temperature sensor in the Supply Controller (SUPC) by the ADC.

The NVM Temperature Log Row can be read at address 0x00806038.

Table 10-14. Temperature Log Row Bitfields Definition
Bit PositionNameDescription
7:0ROOM_TEMP_VAL_INTInteger part of room temperature in °C
11:8ROOM_TEMP_VAL_DECDecimal part of room temperature
19:12HOT_TEMP_VAL_INTInteger part of hot temperature in °C
23:20HOT_TEMP_VAL_DECDecimal part of hot temperature
31:24ROOM_INT1V_VAL2’s complement of the internal 1V reference drift at room temperature (versus a 1.0 centered value)
39:32HOT_INT1V_VAL2’s complement of the internal 1V reference drift at hot temperature (versus a 1.0 centered value)
51:40ROOM_ADC_VALTemperature sensor 12bit ADC conversion at room temperature
63:52HOT_ADC_VALTemperature sensor 12bit ADC conversion at hot temperature
Important: Hot temperature corresponds to the maximum operating temperature +/- 5%, hence 85°C +/- 5% (package grade 'U') or 125°C +/- 5% (package grade 'F').
