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: This is the limit to which V_DD can be lowered in Sleep mode without losing RAM data. See the following figure, POR and POR REARM with Slow Rising V_DD. Please see Reset, WDT, Oscillator Start-up Timer, Power-up Timer, Brown-out Reset and Low-Power Brown-out Reset Specifications for BOR and LPBOR trip point information.
