Oxford Semiconductor First to Market with USB/FireWire Dual SATA Storage Controller; Embedded Encryption Safeguards External Data.MILPITAS, Calif. -- Oxford Semiconductor Inc., a leading provider of high-performance connectivity solutions for consumer, storage and multimedia applications, today announced the industry's first configurable USB/FireWire dual SATA (Serial ATA) A serial version of the ATA (IDE) interface, which has been the de facto standard hard disk interface for desktop PCs for more than two decades. The original Parallel ATA (PATA) interface was launched in 1986. storage controller with encryption. The only SATA storage controller to feature an embedded encryption engine, the OXUF924DSE 1. DSE - Display Screen Equipment. See Visual Display Unit. 2. DSE - Data Structure Editor. from Oxford Semiconductor enables external storage manufacturers to provide users with the option of highly robust data security. By integrating hardware-enabled encryption, the controller also ensures that high data transfer speeds are maintained, at in excess of 80Mbytes/sec. Bridging between dual SATA disks and USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 2.0, FireWire400 and FireWire800 ports, the OXUF924DSE offers real-time 128-bit encryption to the Advanced Encryption Standard (cryptography, algorithm) Advanced Encryption Standard - (AES) The NIST's replacement for the Data Encryption Standard (DES). The Rijndael /rayn-dahl/ symmetric block cipher, designed by Joan Daemen and Vincent Rijmen, was chosen by a NIST contest to be AES. (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. 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 Interleaving or multiplexing data to increase speed. See disk striping. striping - data 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 See physical layer and physical. 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 IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 1394b PHY offers backwards compatibility with the IEEE1394a standard. The chips' 480Mbits/sec 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 Product Differentiation A source of competitive advantage that depends on producing some item that is regarded to have unique and valuable characteristics. . A 12Mbits/sec embedded UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice is provided for firmware code development and debug To correct a problem in hardware or software. Debugging software means locating the errors in the source code (the program logic). Debugging hardware means finding errors in the circuit design (logical circuits) or in the physical interconnections of the circuits. , and field upgrades are simple to implement via the FireWire and USB interfaces.
