1. On devices in WLCSP64+2 package, if IRROFF is set to VDD, the supply voltage can drop to 1.7 V when the device

operates in the 0 to 70 °C temperature range using an external power supply supervisor (see Section 3.16).

2. When the ADC is used, refer to Table 66: ADC characteristics.

3. It is recommended to power VDD and VDDA from the same source. A maximum difference of 300 mV between VDD and

VDDA can be tolerated during power-up and power-down operation.

4. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJmax.

5. In low-power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax.
