6.3.2

Operating conditions at power-up / power-down

The parameters given in Table 21 are derived from tests performed under the ambient

temperature condition summarized in Table 20.

6.3.3

Embedded reset and power control block characteristics

The parameters given in Table 22 are derived from tests performed under the ambient

temperature and supply voltage conditions summarized in Table 20: General operating

conditions.

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

2. In low power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax (see Section 7.4:

Thermal characteristics).
