9.0 DEVICE CONFIGURATION EXAMPLES
USB Bus-Powered and Self-Powered Configurations
Figure 1.
The figure above illustrates a typical USB bus-powered configuration. A USB bus-powered
device gets its power from the USB bus.
Figure 2.
Figure 2 illustrates a typical USB self-powered configuration. A USB self-powered device gets
its power from its own power supply and does not draw current from the USB bus.
Figure 3.
Figure 3 shows how to configure the DLP-2232H to interface with a microcontroller via the
parallel 245 FIFO interface mode. In this example, the target electronics can operate at from
3.3 - 5 volts since the DLP-2232H interface I/O pins are 5 volt tolerant.
