† Data in “Typ.” column is at 3.0V, 25℃ 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. See Reset, WDT, Oscillator Start-up Timer, Brown-Out Reset and Low-Power Brown-Out Reset Specifications for BOR and LPBOR trip point information. When the I3C Low-Voltage buffers are used within the 1.4V-1.62V range of V_DDIOx power domain, a minimum device V_DD of 2.4V is required for proper operation. The MVIO domains are forced in reset when configured to operate in low-voltage range (0.95V-1.62V).
