Cypress Semiconductor Corp. has introduced the first dedicated peripheral controller for multimedia handsets. The new West Bridge Antioch controller provides the highest-performance handset-to-PC connection for rapid transfers of music files, photos and videos.

The Antioch controller, the first member of the West Bridge family, offers a direct path from high-speed USB 2.0 to the latest handset storage devices such as Secure Digital (SD), MultiMedia Card (MMC), Hard Disk Drive (HDD) and NAND Flash. By fully offloading management of USB and storage from the main baseband processor, the controller saves critical processor resources and allows a mobile handset to maintain full functionality while simultaneously uploading or downloading multimedia files, synchronising PIM data, or even using the phone as a PC modem.

The West Bridge Antioch device marks the debut of Cypress' Simultaneous Link to Independent Multimedia (SLIM) architecture, which manages dedicated paths to allow the Processor Host (P-port), Mass Storage (S-port) and High-Speed USB (U-port) interfaces to connect independently. This innovative architecture, combined with 16 USB end-points, creates new simultaneous usage models when the phone is connected to a PC, and a better overall user experience.

The West Bridge Antioch controller is a dedicated mobile handset solution that features a low-power 1.8V core to support an I/O voltage range of 1.8V to 3.3V seamlessly interfacing with several generations of handset processors. The device comes in a small 100 ball Fine Pitch Ball Grid Array (fpBGA) package that measures only 6-by-6mm and 0.5mm pitch. Antioch leverages Cypress' 0.13µm C8 low power process technology to slash dynamic and standby current. Additionally, Antioch supports standard cell phone frequencies such as 19.2MHz and 26MHz for clock input, removing the need for an additional crystal.

The CYWB0124AB West Bridge Antioch controller meets all USB 2.0 certification criteria and is sampling today with full production expected in first quarter of 2007. Pricing in five lakh unit quantities is under Rs.182.08 ($4).
