Fujitsu USB 3.0-SATA Controller for RAID Storage Applications Earns USB-IF Compliance Certification

September 16, 2010 by | Comments

Sunnyvale, Calif. , September 15, 2010 — Fujitsu Semiconductor America, Inc. (FSA) today announced that another member of its growing family of USB 3.0-SATA bridge ICs, the MB86E50, has passed USB-IF compliance testing and is now certified as compliant with the SuperSpeed USB (USB 3.0) standard by the USB Implementers Forum. The certification of the MB86E50 brings Fujitsu to three certified USB 3.0-SATA bridge ICs along with the MB86C30 and MB86C31 (see a press release on August 24, 2010,

The MB86E50 is the newest addition to the Fujitsu USB 3.0-SATA bridge IC family. Like the MB86C31, it integrates a 32-bit RISC MPU, and comes with available hardware-based high-speed encryption. Both the MB86C31 and MB86E50 deliver throughput rates up to 5Gbps, permit hot plugging of devices, and support the USB-attached SCSI (UAS) and Bulk-only Transport (BOT) protocols. Both chips also offer full legacy support for high-speed USB (480Mbps) and full-speed USB (12Mbps) devices, as well as for ATA, SATA Gen2i (3Gbps) and SATA Gen1i (1.5Gbps) drives (see a press release on September 8, 2010,

The MB86E50 series supports RAID 0 (striping) and RAID 1 (mirroring) as well as JBOD (“just a bunch of disks”) and dual LUN configurations. Available in a compact 68-pin QFN (0.4mm pitch, 8mm x 8mm) package, the MB86E50 is an ideal design choice for demanding RAID storage applications that use external hard disk or solid state drives.

“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,” stated Jeff Ravencraft, president and chairman, USB-IF. “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.”

“The MB86E50 is the third of our USB 3.0-SATA bridge ICs to be awarded compliance certification by the USB Implementers Forum,” said Yoshi Masuda, senior manager of marketing, Fujitsu Semiconductor America. “We continue to win designs for external drives and mass storage systems globally with these new products, as customers value the performance benefits provided by the USB 3.0 specification.”

To complement the specification and enable measurement of compliance in real products, the USB-IF has instituted a compliance program that provides reasonable measures of acceptability. Products that demonstrate this level of acceptability are added to the Integrators List and have the right to license the USB-IF logo. To learn more about the USB Implementers Forum visit
