† - Data in “Typ.” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested.

Note:
  1. This is the limit to which VDD can be lowered in Sleep mode without losing RAM data.
  2. See the following figure, POR and POR REARM with Slow Rising VDD.
  3. See “Reset, WDT, Power-up Timer, and Brown-Out Reset Specifications” for BOR trip point information.
