FireWire to IDE bridge chip supports RAID
Firmware enhancements to the popular OXFW911 FireWire to IDE bridge chip enable the development of simple, low cost RAID storage products for personal and small business application.
Integrated solution for high-speed data streaming
Combining an 800Mbit/s 1394B link layer and PHY controller with a 480Mbit/s USB2.0 PHY, the OXUF922 programmable bridge chip provides a fully integrated solution for high-speed data streaming.
With one of the chip's two integrated SATA cores and PHYs configurable as either a host or a device port, the controller actually offers disk enclosure designers the option of either the 3Gbit/s eSATA interface or an interface to a second SATA hard disk.
In its dual SATA disk mode, the OXU931DS supports both disk striping (RAID 0) and disk spanning for larger storage capacity applications, via the standard USB2.0 interface.
This ARM7 processor based controller is also one of the first in its class to offer the benefits of full software control of the eSATA datapath.
External storage designers have as a result the ability to increase product differentiation through the addition of functionality such as pushbutton backup.
The high-speed read and write data transfer provided by the storage controller's embedded USB2.0 core means that host performance is able to be maintained at maximum.
The USB interface handles full and high speed modes, employs bulk-only transport mass storage class device protocol and is backwards compatible with USB1.1.
The OXU931DS storage controller comes complete with Windows and Mac OS compatible drivers for standard storage and button notification applications and for control of the chip's 12 GPIOs.
Firmware is easily upgraded via the USB port.
Evaluation boards are available through distribution channels.
