Cypress introduces peripheral controller for multimedia mobile handsets

Supplier News

Cypress Semiconductor Corp. introduced the world’s first dedicated peripheral controller for multimedia handsets. The new West Bridge Antioch controller provides high-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 new 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’s 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 endpoints, creates new simultaneous usage models when the phone is connected to a PC, and a better overall user experience.

According to Cypress, working closely with the leading mobile handset companies, they developed the West Bridge Antioch controller to achieve a new level of performance and connectivity. The Antioch controller opens up high-speed data transfer of multimedia files without hindering the primary communication function of the phone.

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