Incorrect temperature sensor calibration data
In some devices, the internal temperature sensor calibration data for 30 degC are invalid for all VRef conditions. Devices with correct calibration data show a difference of at least 30 LSBs between the different VRef conditions. When using incorrect calibration data with the internal temperature sensor ADC samples, the calculated results can be unreliable. Calibration data for 85 degC are not affected.
This erratum affects devices with Lot Trace Code dated prior to 01/2011.
Recalibrate the temperature sensor for 30 degC at the application level.
