USB/Mass Storage Peripheral Controller 81-Pin WLCSP T/R

The Simultaneous Link to Independent Multimedia (SLIM) architecture allows three different interfaces (the P-port, the S-port, and the U-port) to connect to one another independently. With this architecture, using Antioch to connect a device to a PC through an USB does not disturb the functions of the device. It still accesses 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 accesses a mass storage device independent of the main processor, or enumerates access to both the mass storage and the main processor at the same time. In a handset, this typically enables the user to use the phone as a thumb drive or download media files to the phone while still having full functionality available on the phone. The same phone even functions as a modem to connect the PC to the web.
