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.

Table 18 provides I/O consumption figures.

1. All VDD_HV_IO conditions for 4.5 V to 5.5 V are valid for VSIO[VSIO_xx] = 1, and all specifications for 3.0 V to 3.6 V are valid

for VSIO[VSIO_xx] = 0.

2. All values need to be confirmed during device validation.

3. Only available on the VDD_HV_IO_JTAG and VDD_HV_IO_ETH segments.

4. CL is the sum of external capacitance. Add device and package capacitances (CIN, defined in the Table 12: I/O input DC

electrical characteristics in this Datasheet) to calculate total signal capacitance (CTOT = CL + CIN).

5. TTL transition time as for Ethernet standard.
