✝ Data in the “Typ.” column is at T_A = 25°C and V_DD = 3.0V unless otherwise specified. These parameters are not tested and are for design guidance only. * These parameters are characterized but not tested in production. Note: During Chip Erase, the Brown-out Detector (BOD) configured with BODLEVEL0 is forced ON. The erase attempt will fail if the supply voltage V_DD is below V_BOD for BODLEVEL0.
