9 USB Port

UC864-E includes an integrated universal serial bus (USB) transceiver, compliant with USB 2.0 specification, for interfacing UC864-E to a computer as a USB peripheral or connecting the UC864-E to other peripherals. It supports the USB low-speed (1.5 Mbits/s) and full-speed (12 Mb/s) modes. In HSDPA (High Speed download Packet Access) mode, the downlink data speed rates up to 7.2Mbps. Hence you need to interface UC864-E to your applications in full-speed (12Mbits/s) mode.

You can use USB for the following purposes: communication with external peripheral devices, debug monitor
