I/O Pad Current Specification

The I/O pads are distributed across the I/O supply segment. Each I/O supply segment is associated to a VDD/VSS supply pair as

described in Table 22.

Table 23 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.
