Integrated 512kb Flash memory Blank Flash memory programming feature via 1394 bus Firmware and Flash Programming Utilities supplied by Oxford Semiconductor 3.
3 Volts operation Low Power CMOS Ultra-thin 128-TQFP package (14 x 14 x 1 mm) DESCRIPTION The OXFW911 is a high-performance 1394 to ATA/ATAPI (IDE) native bridge with an integrated target Serial Bus Protocol (SBP-2 ) controller.
By supporting the SBP-2 protocol, the device can use generic SBP-2 drivers available in the Microsoft Windows 98SE, Microsoft Windows 2000, Microsoft Millennium and Apple MacOS (8.
4 to 9.
04) operating systems.
MacOS support also includes booting from Firewire disk.
The device is ideally suited for smart-cable or tailgate interface applications for removable-media drives, compact flash card readers, CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-RAM and hard disk drives, allowing IDE drives to be connected to a 1394 serial bus in a plug-and-play fashion.
Both ATA and ATAPI devices are supported using the same firmware.
This highly integrated device offers a two-chip solution to native bridge applications using an external 1394 PHY.
