Fujitsu expands USB 3.0-SATA bridge controllers

Features transfer speeds up to 5Gbps, hot plugging of devices, and support for the USB attached SCSI (UAS)

By CBR Staff Writer

Fujitsu Semiconductor America, a provider of USB 3.0-compliant technology, has expanded lineup of USB 3.0-SATA bridge controllers with the introduction of the new MB86E50 series for external USB 3.0 RAID storage devices.

The new MB86E50 is designed for external USB 3.0 dual-port RAID and non-RAID configurations, and supports RAID 0 (striping) and RAID 1 (mirroring), along with JBOD (‘just a bunch of disks’) and Dual LUN configurations.

The company said that the storage device’s integrated high-speed encryption hardware engine makes the controller an ideal design choice for RAID storage applications using external hard disks or solid state drives.

The new MB86E50 features transfer speeds up to 5Gbps, hot plugging of devices, and support for the USB attached SCSI (UAS) and Bulk-only Transport (BOT) protocols.

In addition, it incorporates a 32-bit RISC MPU and an embedded SSCG to optimise SuperSpeed performance while reducing EMI.

The MB86E50 includes full legacy support for high-speed USB (480Mbps) and full-speed USB (12Mbps) devices, and supports SATA Gen2i (3Gbps) and Gen1i (1.5Gbps), ATA, and ATAPI drives.

Fujitsu Semiconductor America marketing senior manager Yoshi Masuda said that with the MB86E50, Fujitsu enables drive and system manufacturers to offer RAID-enabled storage based on the state-of-the-art USB 3.0 standard.

"The USB 3.0-SATA bridge controller combines the advantages of USB 3.0 including higher transfer rates, plug-and-play interoperability, and hot-swapping with the greater reliability and performance potential of RAID configurations," Masuda said.

"Available with a hardware-based high-speed encryption engine, the MB86E50 USB 3.0-SATA bridge controller offers a truly robust, secure and flexible external storage offering."
