1 VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified.
2 VDD as mentioned in the table is VDD_HV_A/VDD_HV_B. All values need to be confirmed during device validation.
3 This is a transient configuration during power-up, up to the end of reset PHASE2 (refer to the RGM module section
of the device Reference Manual).
4 CL includes device and package capacitance (CPKG < 5 pF).
5 The configuration PAD3V5 = 1 when VDD = 5 V is only transient configuration during power-up. All pads but
RESET and Nexus output (MDOx, EVTO, MCKO) are configured in input or in high impedance state.
