46.2 Register Descriptions
46.2.1 Temperature Sensor Calibration Data Register (TSCDRH, TSCDRL)
The TSCDRH and TSCDRL registers store temperature sensor calibration data measured for each chip at factory
shipment.
Temperature sensor calibration data consists of the high and low bytes of the overall value (CAL
88
) obtained by using the
12-bit A/D converter to convert the voltage output by the temperature sensor under the condition of Ta = Tj = 88°C and
AVCC0 = VREFH0 = 3.3 V. The TSCDRH register stores the higher 4 bits of the converted value, and the TSCDRL
register stores the lower 8 bits.
The voltage V1 output by the temperature sensor under the condition of Ta = Tj = 88°C can be calculated from the
converted value CAL
88
according to the formula below.
V1 = 3.3 × CAL
88
/4096 [V]
Note that voltage V1 is independent of both the AVCC0 and VREFH0 voltages.
