VDD

Standard operating voltage

VDDA(1)

1. When the ADC is used, refer to Table 59: ADC characteristics.

Analog operating voltage

(ADC not used)

Must be the same potential

as VDD(2)

2. 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 operation.

Power dissipation at TA =

85 °C for suffix 6 or TA =

105 °C for suffix 7(3)

3. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJmax (see Table 6.7: Thermal

characteristics on page 132).
