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.
Bit Position | Name | Description |
---|---|---|
7:0 | ROOM_TEMP_VAL_INT | Integer part of room temperature in °C |
11:8 | ROOM_TEMP_VAL_DEC | Decimal part of room temperature |
19:12 | HOT_TEMP_VAL_INT | Integer part of hot temperature in °C |
23:20 | HOT_TEMP_VAL_DEC | Decimal part of hot temperature |
31:24 | ROOM_INT1V_VAL | 2’s complement of the internal 1V reference drift at room temperature (versus a 1.0 centered value) |
39:32 | HOT_INT1V_VAL | 2’s complement of the internal 1V reference drift at hot temperature (versus a 1.0 centered value) |
51:40 | ROOM_ADC_VAL | Temperature sensor 12bit ADC conversion at room temperature |
63:52 | HOT_ADC_VAL | Temperature 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').
