33.8 BOD and POR Characteristics

Table 33-8. Power Supply Characteristics
SymbolDescriptionConditionMin.Typ.Max.Unit
SRONPower-on Slope--100(1,2)V/ms
Note:
  1. For design guidance only and not tested in production.
  2. A slope faster than the maximum rating can trigger a Reset of the device if changing the voltage level after an initial power-up.
