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.
Bridging between dual SATA disks and USB2.0, FireWire400 and FireWire800 ports, the OXUF924DSE offers real time 128bit encryption to the Advanced Encryption Standard (AES).
Supporting secure token, software password and biometric (fingerprint) sensor encryption authentication methods, the chip provides designers with the flexibility to create multiple storage products from a single hardware platform.
To simplify new product development and reduce time to market, the OXUF924DSE shares a common software base with all other devices in Oxford's market leading range of USB and FireWire combination storage controllers.

Oxford Semiconductor has added an embedded compatibility mode to its 16bit PC Card UART bridge IC that allows generic device drivers to access the 15Mbit/s asynchronous UART and a local bus interface.
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.
In addition, the chip is backed by a comprehensive software development kit, an evaluation board and a selection of encrypted storage reference designs.
Storage methodologies supported by the chip's dual SATA disk interface include disk striping (RAID0), disk mirroring (RAID1) and disk spanning.
In striping and spanning modes up to four disks can be managed, allowing high reliability, high capacity storage solutions to be achieved.
The OXUF924DSE features an embedded FireWire PHY interface and Link layer operating at up to 800Mbits/sec and uses hardware acceleration to achieve industry leading data read and data write performance, irrespective of data block size.
The IEEE1394b PHY offers backwards compatibility with the IEEE1394a standard.
The chips' 480Mbit/s USB2.0 Link and PHY cater for full and high speed USB operating modes and using the mass storage device protocol ensure fastest possible read and write transfers.
The interface is backwards compatible with USB1.1 and is supported by an integral 18Kbyte data cache.
ARM7 processor based and integrating 8Kbyte of closely coupled RAM, a 1Mbyte external Flash interface and 10 GPIOs, the OXUF924DSE provides external storage designers with significant opportunities for product differentiation.
A 12Mbit/s embedded UART is provided for firmware code development and debug, and field upgrades are simple to implement via the FireWire and USB interfaces.
