Keywords:USB 3.0  USB-IF  SATA bridge IC 

Fujitsu Semiconductor Asia Pte Ltd adds the MB86E50 to its family of USB 3.0-SATA bridge ICs that has completed USB Implementers Forum compliance testing and is now certified as compliant with the SuperSpeed USB (USB 3.0) standard by the USB-IF.

The MB86E50 incorporates a 32bit RISC MPU, and offers hardware-based high-speed encryption. The MB86E50 drives throughput rates up to 5Gbit/s, allows hot plugging of devices, and complies with the USB-attached SCSI (UAS) and BOT protocols. The chip also claims full legacy support for high-speed USB (480Mbit/s) and full-speed USB (12Mbit/s) devices, as well as for ATA, SATA Gen2i (3Gbit/s) and SATA Gen1i (1.5Gbit/s) drives.

The MB86E50 series supports RAID 0 (striping) and RAID 1 (mirroring) as well as JBOD and dual LUN configurations. The chip comes in a compact 68-pin QFN (0.4mm pitch, 8mm x 8mm) package and targets demanding RAID storage applications which use external hard disc or solid state drives.

President and chairman of USB-IF, Jeff Ravencraft says, "SuperSpeed USB is an incredible advancement of the USB technology that consumers know and love, and we're excited to witness broad industry support for SuperSpeed USB technology." He adds, "The growing number of certified SuperSpeed USB products and devices in the market is a clear indication of intense interest in, and momentum behind SuperSpeed USB."

To complete the specification and permit measurement of compliance in real products, the USB-IF has established a compliance programme which sets reasonable measures of acceptability. Products that possess this level of acceptability are added to the Integrators List, having the right to license the USB-IF logo.
