revision 1. 6 nov. 16, 2000 - 3 - GL620USB 1. features conforms to usb 12mbps specification , version 1.1 patent ed architecture single chip solution for host - to - host communication file transfer application software running on windows 98 and windows 2000 up to 8.6mbps transfer rate suitable for mobile and soho environment tiniest solution in the market ? 16 - pin sop on - chip 3.3v output 12mhz external clock internal power - on reset p ower management support
revision 1. 6 nov. 16, 2000 - 4 - GL620USB 2. functional overview the GL620USB provides a single - chip solution for connec ting two or more pcs via their usb ports. according to usb protocol, the pc is the host and the device is a slave, where the host initiates all the usb traffic and the slave responds to the host ? s requests. in other words, a host cannot talk to another hos t via usb protocol; instead, a host can only talk to one or more devices. the GL620USB ? s patent - pending architecture overcomes the usb inherently incompatibility of connecting two or more pcs by providing two independent usb transceivers and sies for each host, i.e., data can be transferred in both directions simultaneously. system diagram GL620USB pc a pc b usb connection usb connection
revision 1. 6 nov. 16, 2000 - 5 - GL620USB 3. applications we provide application program to share file between 2 pcs. this application is easy to install for end user s . besides, the file transfer rate of the a pplication program (combined with GL620USB) is up to 8.6mbps. with this file transfer application, pcs can share files on all local drives, such as hard drive, floppy, cd - rom and network drives. the GL620USB - lite file transfer function can be integrated with the following form factors: usb standalone cable usb standalone hub usb monitor with hub pc host
revision 1. 6 nov. 16, 2000 - 6 - GL620USB 4. functional description block diagram of GL620USB - lite the GL620USB - lite is equipped with two full - speed usb ports, and each port has four endpoints to provide different function s as follows: - endpoint 0: control transfer - endpoint 1: bulk - read transfer - endpoint 2: bulk - write transfer - endpoint 3: interrupt transfer two 8 - bytes fifo and four 64 - bytes fifo are built in the device as follows: - left 8 - byt e fifo: provide a pipe to link left endpoint 0 and right endpoint 3. for example, if left host want s to communicate with right host, left host can issue a no data control transfer and the setup command will be stored 64 byte fifo 64 byte fifo 8 byte fifo 8 bytes fifo usb interface usb interface micro- controller usb registers & fifo control d+ d- d+ d-
revision 1. 6 nov. 16, 2000 - 7 - GL620USB in the left 8 - byte fifo. right host can request a n interrupt transfer to get the setup command from left host. the status stage of the left side control transfer will not be terminated until that the right side get the setup command via interrupt transfer. - right 8 - byte fifo: provide a pipe to link right endpoint 0 and left endpoint 3. - left 64 - bytes data0/data1 fifos: provide a pipe to link left endpoint 2 and right endpoint 1. for example, if left host want s to transfer data to right host, left host can issue bulk write transfer and the pay load will be stored in the left 64 - byte fifos. right host can request a bulk read transfer to get the data from left host. - right 64 - bytes data0/data1 fifos: provide a pipe to link right endpoint 2 and left endpoint 1.
