OXUF924DSa And OXUF924DSb: New SATA Bridges For Portable Drives
Oxford Semiconductor introduced OXUF924DSa and OXUF924DSb chips a complete solution for bridging between SATA disks to USB2.0, FireWire400, and FireWire800 (DSB only). The OXUF924DSA is USB2.0 and FireWire400, while the OXUF924DSB also supports FireWire800. Integrating a full USB2.0 link/Phy and FireWire link, the chips minimise the total component count for an external drive product.
The novelties are compatible with latest generation serial ATA drives and supports dual disks and operate at 1.5GHz, assuring a disk interface data rate of 150MB/sec. The SATA interface allows external storage products to follow the current transition of hard drives from Parallal ATA to Serial ATA.
Dual SATA allows connection of 1 or 2 SATA drves with hardware striping, spanning and mirroring for ultimate performance. Alternatively, one SATA port can be configured as an input enabling eSATA to SATA.
Bridges are based on ARM7 core with 8KB RAM, 1MB of external flash memory and 12 General Purpose Input/Output channels. In the process of development firmware can be uploaded through an integrated asynchronous transceiver (12Mbps), while in ready solutions firmware can be upgraded via FireWire or USB ports.
OXUF924DSa (FireWire400) costs $8.70, OXUF924DSb (FireWire800) — $11.90 in over 10K quantities.
