I/O pad current specification

The I/O pads are distributed across the I/O supply segment. Each I/O supply is associated

to a VDD/VSS_HV supply pair as described in Table 20.

Table 21 provides I/O consumption figures.

In order to ensure device reliability, the average current of the I/O on a single segment

should remain below the IAVGSEG maximum value.

In order to ensure device functionality, the sum of the dynamic and static current of the I/O

on a single segment should remain below the IDYNSEG maximum value.

VDD = 3.3 V ± 10 % / 5.0 V ± 10 %, TA = 40 to 125 °C, unless otherwise specified.

VDD as mentioned in the table is VDD_HV_A/VDD_HV_B.

All values need to be confirmed during device validation.

CL includes device and package capacitances (CPKG < 5 pF).
