* These parameters are characterized but not tested.

† Data in “Typ.” column is at 3.0V, 25℃ 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, Oscillator Start-up Timer, Brown-Out Reset and Low-Power Brown-Out Reset Specifications for BOR and LPBOR trip point information.

Note:
  1. When NPOR is low, the device is held in Reset.
  2. TPOR 1 μs typical.
  3. TVLOW 2.7 μs typical.
