Operating conditions
Table 87.
1. T
When the power supply is between 2.7 and 2.95 V (V
guaranteed functional area or in reset state, thus allowing deterministic application behavior.
However the LVD may generate a reset below 2.95 V and the user should therefore not use
the device below this level when the LVD is enabled.
