advance information CYWB012X family document #: 001-05898 rev.*c page 2 of 9 description west bridge ? antioch? is a peripheral mass storage controller that enhances a proc essor system with flexible mass storage support and high speed usb connectivity. antioch has three different ports that enable connections among a main processor (p-port), one or more mass storage devices (s-port), and a usb host (u-port). antioch?s unique slim architecture allows these three ports to interact simultaneously and independently of each other. this offers connectivity from usb to storage (typically used for pc high speed data download), from usb to processor (used for synchronization operations), and from processor to storage. connected as a slave to a main processor, antioch adds support for high speed usb and mass storage access including mmc, mmc+, sdio, ce-ata, slc and mlc nand. antioch further enables new usage models by allowing usb to directly connect to a storage device independent of the main processor. antioch is primarily targeted at handsets, to enable high speed connectivity to a pc through usb, and support for the latest mass storage devices. antioch can, for instance, enable a multimedia phone to support hdd or nand mlc storage, with the ability to download multimedia data at high speed from a pc directly to the storage device. slim architecture the simultaneous link to independent multimedia (slim) architecture allows three interfaces (p-port, s-port, and u-port) to connect to one another independent of each other. with this architecture, connecting the device using antioch to a pc through usb does not disturb any of the functions of the device, which 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 enables to use the phone as a thumb drive or download media files to the phone while still having full functionality available on the phone. it also allows using the same phone as a modem to connect the pc to the web. mass storage support (s-port) the s-port can be configured in two different modes, either simultaneously supporting an sdio/mmc+/ce-ata port and a 8 nand port, or supporting a unique 16 nand access port. antioch, as part of its mass storage management functions, can fully manage a nand device. an embedded 8051 manages the actual reading and writing of the nand, along with its required protocols, including single level cell (slc) and multi-level cell (mlc) nand. it performs standard nand management functions such as ecc and wear leveling. processor interface (p-port) communication with the external processor is realized through a dedicated processor interface. this interface supports both synchronous and asynchronous sram-mapped memory accesses. this ensures straightforward electrical communications with the processor, which may also have other devices connected on a shared memory bus. the memory address is decoded to access any of the multiple endpoint buffers inside antioch. these endpoints serve as buffers for data between each pair of ports, for example, between the processor port and the usb port. the processor writes and reads into these buffers via the memory interface. access to these buffers is controlled by either using a dma protocol or an interrupt to the main processor. these two modes are configurable by the external processor. as a dma slave, antioch generates a dma request signal to signify to the main processor that a specific buffer is ready to be read from or written to. the external processor monitors this signal and polls antioch for the specific buffers ready for read or write. it then performs the appropriate read or write operations on the buffer through the processor interface. this way, the external processor only deals with the buffers to access a multitude of storage devices connected to antioch. in the interrupt mode, antioch communicates important buffer status changes to the external processor using an interrupt signal. the external processor then polls antioch for the specific buffers ready for read or write, and it performs the appropriate read or write operations via the processor interface. configuration the west bridge antioch device includes configuration and status registers that are accessible as memory-mapped registers through the processor interface. the configuration registers allow the syst em to specify certain behavior of antioch. for example, it can mask certain status registers from raising an interrupt. the status registers convey various status of antioch, such as the addresses of buffers for read operations. packaging the west bridge antioch is available in two packaging options: as a bare die or in a 6 6 mm, 100-pin very fine-pitch ball grid array (vfbga). as a 100-pin vfbga, it consumes a small amount of space and allows for easy debug and connections to the other device s in the system.
