Cypress West Bridge® Controllers

Cypress West Bridge® Controller family offers a revolutionary architectural enhancement for embedded applications. Peripheral controllers in the West Bridge family function as a companion chip to an embedded central processing unit (CPU) to free it from data-intensive operations. West Bridge controllers achieve superior data transfer performance by enabling simultaneous and independent data paths between USB port, mass storage devices and embedded processors.

Product Brochure


The Cypress's West Bridge® Antioch™ peripheral controller is the world's first dedicated peripheral controller for multimedia handhelds, providing the highest-performance handset-to-PC connection for rapid transfers of music files, photos and videos. The Antioch controller, offers a direct path from Hi-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, synchronizing PIM data, or even using the phone as a PC modem.

Features
  • Integration: Hi-Speed USB 2.0 compliant with built-in PHY
  • SLIM® Architecture:simultaneous data paths among USB, storage, and processor
  • Ultra Low Power: 1.8 V core operation
  • Mass Storage Support: MMC, MMC, SD
  • Flexible Processor I/F Support: SRAM, PCRAM
  • Flexible Clock: Selectable clock input at 19.2 MHz, 24 MHz, and 26 MHz
  • Small Footprint:6x6 mm 100-pin VFBGA package
Applications
  • Cellular Phones
  • Portable Media Players
  • Personal Digital Assistants
  • Digital Cameras
  • Portable Video Recorder
