West Bridge(R) Antioch(TM) Peripheral Controller
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, Antioch 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.
The West Bridge Antioch device is based on Cypress's Simultaneous Link to Independent Multimedia(TM) (SLIM(TM)) 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.
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. 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.
