2. Features
Easy use/connect (IDE bus connection)
Allows USB devices to be controlled as IDE devices
The main CPU is capable of controlling USB storage devices connected to this LSI as IDE devices.
This LSI handles connection processing for the USB hub, no USB driver is required at the main CPU.
An ATA/ATAPI driver should be installed at the main CPU.
A main CPU with an installed ATA/ATAPI driver is capable of controlling USB storage devices via
this LSI.
Easy use/connect (CPU bus connection)
Also permits CPU bus connections (interface voltage: 1.8 V to 3.3 V)
The LSI can also be connected to a memory bus to connect to the main CPU without an IDE bus. An
ATA/ATAPI driver should be installed in the main CPU. The registers used to control this LSI are
ATA task file registers.
High-speed transfer
Transfer rate 31 MB/s (Seiko Epson figures)
Transfer rates of up to 31 MB/s can be achieved with ATA100 and USB High-Speed connection.
Embedded Host silicon authentication
High-quality USB signal
This LSI includes an Embedded Host function (including authentication software) for silicon
authentication. The S1R72U16 USB 2.0 PCB Design Guide and S1R72U16 Embedded Host
Compliance Manual are also provided to help the user obtain USB logo certification.
Product (system) development support functions
History display
LSI internal processing history can be displayed using the serial (asynchronous) interface. The
