12. Current consumption
Table 120 shows the current consumption when two ports are active, that is, the
SEL2PORTS pin is connected to VDD.
[1]
When one or two full-speed or low-speed power devices are connected, the current consumption is comparable with the current
consumption when no high-speed devices are connected. There is a difference of approximately 1 mA.
Table 121 shows the current consumption when four ports are active, that is, the
SEL2PORTS pin is connected to ground.
