Fresco Logic 4-port USB 3.0 Host Controller Now Available
Release Date : September 27 , 2011

The FL1100 4-port USB 3.0 Host Controller, the latest member of the GoXtream™ family, inherits all of the technologies from the Patented GoXtream™ architecture and adds the latest advancements.

TAIPEI, Taiwan – September 22, 2011 – Fresco Logic, a global fabless semiconductor company that develops and markets advanced connectivity solutions, announced availability of its FL1100 4-port USB 3.0 Host Controller with fully integrated USB transceiver. FL1100 not only delivers the most cost-effective path to a USB-rich system, but also offers best-in-class backwards compatibility with all USB 2.0 speeds. As the latest member of the GoXtream™ family (which now includes 1, 2, and 4-port members), FL1100 includes all of the advanced technologies from the Patented GoXtream™ architecture and adds the latest features, including UASP (USB Attached SCSI Protocol), hardware-based LPM, and flexible USB charging.

The hardware based multi-stream, multi-threaded parallel processing engines deliver full bandwidth to each USB 3.0 port, and the FL1100 has been further optimized for multiple device operation simultaneously. As is the tradition of the GoXtream™ family, no firmware and a high level of integration benefits simpler and swifter system integration and adds up to a low TCO. With xHCI 1.0 compliance, FL1100 guarantees the system has the best compatibility now and in the future and sets the performance standard while delivering even lower power consumption. FL1100 features 4 USB 3.0 downstream ports in a 116-pin, 9mm x 9mm footprint DRQFN (dual-row) package.

Fresco Logic’s GoXtream™ router minimizes latency and protects high-bandwidth real-time data streams while still allowing access to ample best effort bandwidth. To the user this means fast backups even while watching high-definition video or other high-bandwidth real-time applications.FL1100 fully supports the UASP (USB Attached SCSI Protocol) standard, the next generation storage protocol designed for USB 3.0. This feature optimizes the transfer efficiency for the 5Gbps channel by eliminating some of the classic BOT (bulk-only transport) bottlenecks. FL1100 also supports hardware-based LPM (Link Power Management). When a USB 2.0 LPM-capable device is attached, FL1100 automatically negotiates with the device for entrance to the low power states. This helps the system manage the link power more effectively and, by eliminating software intervention, allows the host CPU to remain in sleep states for longer periods of time. This second factor can result in power savings that are orders of magnitude larger than the link power savings alone.

Fresco Logic’s FL1100 is compliant with Battery Charging (BC) Specification Revision 1.2: Charging Downstream Port (CDP), and China Charging YD/T 1591-2009 Standards. FL1100’s proprietary hybrid-charging mode automatically distinguishes BC-compliant devices or China Charging devices and handshakes accordingly. With appropriate power supply design, system designers can easily support USB charging without extra discrete USB charging components.
