Dev kit has storage interfaces covered
A new development kit provides all the tools needed to create FireWire 800 (IEEE1394b) and USB 2.0 compliant storage products with the minimum amount of effort and the lowest risk.
Evaluation for ARM-based bridge chip
A new IDE bridge board from Oxford Semiconductor provides "plug and go" evaluation of the OXUF922 bridge chip in FireWire 800 (IEEE1394b) and USB 2.0 compliant hard disk drive applications.
In supporting the second generation of the 1394 (FireWire) standard, the OXUF922 delivers twice the bandwidth of 1394A, is backwards compatible and offers additional support for longer cable lengths for home or office networking.
The chip is based on Oxford's popular OXFW911 IDE/1394 bridge chip, integrated into more than half of all external storage devices.
Inclusion of the USB2.0 integrated PHY and link layer guarantees connectivity with any PC platform over USB1.X and USB2.0.
Complying with the ATA6 high-density drive specifications, the UF922's 133MHz IDE controller handles a datarate of 80Mbyte/s and assures compatibility with all magnetic, optical and CompactFlash media.
In nonstorage applications, the IDE interface can be reconfigured as a high-performance DMA host controller port.
A 12Mbit/s buffered UART is also included which provides a direct data communication interface to modems and Bluetooth radios and allows "back channel" monitoring in RAID applications.
Controlling data flow through the OXUF922, an on-chip ARM7TDMI processor enables highly differentiated products to be developed in a simple C programming environment.
