USB/Mass Storage Peripheral Controller 100-Pin VF-BGA

The Simultaneous Link to Independent Multimedia (SLIM) architecture allows three different interfaces (P-port, S-port and U-port) to connect to one another independently. With this architecture, connecting a device using Astoria to a PC through USB does not disturb any of the functions of the device. The device can still access mass storage at the same time the PC is synchronizing with the main processor. The SLIM architecture enables new usage models in which a PC can access a mass storage device independent of the main processor, or enumerate access to both the mass storage and the main processor at the same time. In a handset, this typically enables using the phone as a thumb drive, downloading media files to the phone while still having full functionality available on the phone, or using the same phone as a modem to connect the PC to the web.
