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.
The chip's embedded USB link and PHY allow for full and high-speed operation to help maximise data throughput.
For storage manufacturers wishing to add higher speed eSATA connectivity to their products, one of the bridge chip's SATA ports can also configured as an input port for future eSATA to SATA connections.
Operating at 1.5GHz, the integrated SATA core and PHY of the OXU921DS optimise the datarate to the external disk interface.
ARM7 processor based and including 8Kbyte of RAM and 12 GPIOs, the bridge chip provides significant scope for highly differentiated product design.
Field upgradeable firmware supplied with the chip includes the USB mass storage protocol, supported as standard by Windows and Apple Mac operating systems.
To help further reduce NRE costs, the OXU921DS shares a common software base with all other bridge chips in the 92X product family and is made available with a complete development kit and evaluation board.
In a 176-pin BGA package, this latest bridge chip is priced at US $7.44 in 10,000-unit quantities.
