Operating conditions

5.3.1

General operating conditions

5.3.2

Operating conditions at power-up / power-down

The parameters given in Table 11 are derived from tests performed under the ambient

temperature condition summarized in Table 10.

VDDA(1)

1. When the ADC is used, refer to Table 56: 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.

3. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJmax (see Section 6.4:

Thermal characteristics).
