1.1.2 Differential Rx Output Electricals
1.2 USB Interface
The USB device interface is compliant with the Universal Serial Bus Specification, Revision 2.0, April 27, 2000. A
USB host uses the USB cable bus and the USB 2.0 device interface to communicate with the chip. The main
features of the USB device interface include:
 High/full speed operation (480/12 Mbps)
 Suspend/host resume/device resume (remote wake-up)
 Built-in DMA engine that reduces interrupt loads on the embedded processor and reduces the system bus
bandwidth requirement for serving the USB device operation
 The USB 2.0 device interface is designed with 3.3V signal level pads.
