3.8.2 I/O Pad V
DD33
Current Specifications
The power consumption of the V
DD33
supply dependents on the usage of the pins on all I/O segments. The
power consumption is the sum of all input and output pin V
DD33
currents for all I/O segments. The output
pin V
DD33
current can be calculated from Table 11 based on the voltage, frequency, and load on all fast
(pad_fc) pins. The input pin V
DD33
current can be calculated from Table 11 based on the voltage,
frequency, and load on all pad_sh and pad_mh pins. Use linear scaling to calculate pin currents for voltage,
frequency, and load parameters that fall outside the values given in Table 11.

These values are estimated from simulation and not tested. Currents apply to output pins for the fast pads only and to input
pins for the slow and medium pads only.
