Power Consumption

This section details the power consumption of the device as measured during various modes of operation. Power dis-

sipation is determined by temperature, supply voltage, and external source/sink requirements.

Example Active Data Transfer Current Calculation: 1 SS+ Port and 2 HS Ports

Active Data Transfer Current (mA @ 3.3V)

{30.8} + {1 * 11.1} + {2 * 10.8} = 63.5

Active Data Transfer Current (mA @ 1.15V)

{410} + {1 * 179} + {2 * 1} = 591

Note:

In the Active Idle and Active Data Transfer sections of Table 9-2, the various port configurations are

indicated via the following acronyms:

SS = USB 3.2 SuperSpeed (Gen 1)

HS = USB 2.0 High Speed
