Temperature Log Row

All values in this row were measured in the following conditions:

• V_DDIN = V_DDIO = V_DDANA = 3.3V
• ADC Clock speed = 1MHz
• ADC mode: Free running mode, ADC averaging mode with 4 averaged samples
• ADC voltage reference = 1.0V internal reference (INT1V)
• ADC input = Temperature sensor

  Table 1. Temperature Log Row Content

  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	12-bit ADC conversion at room temperature
  63:52	HOT_ADC_VAL	12-bit ADC conversion at hot temperature

The temperature sensor values are logged during test production flow for Room and Hot insertions:

• ROOM_TEMP_VAL_INT and ROOM_TEMP_VAL_DEC contains the measured temperature at room insertion (e.g. for ROOM_TEMP_VAL_INT=25 and ROOM_TEMP_VAL_DEC=2, the measured temperature at room insertion is 25.2°C).
• HOT_TEMP_VAL_INT and HOT_TEMP_VAL_DEC contains the measured temperature at hot insertion (e.g. for HOT_TEMP_VAL_INT=83 and HOT_TEMP_VAL_DEC=3, the measured temperature at room insertion is 83.3°C).

The temperature log row also contains the corresponding 12-bit ADC conversions of both Room and Hot temperatures:

• ROOM_ADC_VAL contains the 12-bit ADC value corresponding to (ROOM_TEMP_VAL_INT, ROOM_TEMP_VAL_DEC)
• HOT_ADC_VAL contains the 12-bit ADC value corresponding to (HOT_TEMP_VAL_INT, HOT_TEMP_VAL_DEC)

The temperature log row also contains the corresponding 1V internal reference of both Room and Hot temperatures:

• ROOM_INT1V_VAL is the 2’s complement of the internal 1V reference value corresponding to (ROOM_TEMP_VAL_INT, ROOM_TEMP_VAL_DEC)
• HOT_INT1V_VAL is the 2’s complement of the internal 1V reference value corresponding to (HOT_TEMP_VAL_INT, HOT_TEMP_VAL_DEC)
• ROOM_INT1V_VAL and HOT_INT1V_VAL values are centered around 1V with a 0.001V step. In other words, the range of values [0,127] corresponds to [1V, 0.873V] and the range of values [-1, -127] corresponds to [1.001V, 1.127V]. INT1V == 1 - (VAL/1000) is valid for both ranges.
