It supports SuperSpeed USB, the USB 3.0 specification , and enables data transfer rates of 5Gbps maximum between external storage devices – such as hard disk drives (HDDs) – and PCs.

Fujitsu Microelectronics Asia Pte Ltd (FMAL) announced the new USB 3.0 - SATA bridge ICs, built with Fujitsus physical layer device (PHY). It supports SuperSpeed USB, the USB 3.0 specification , and enables data transfer rates of 5Gbps maximum between external storage devices such as hard disk drives (HDDs) and PCs. The new IC, MB86C30A, is the first in the MB86C30 Series of USB 3.0-SATA bridge ICs, and when embedded in PC peripheral devices, enables over 10-fold faster data transfer rates in comparison to the USB 2.0 specification. In addition to the bridge functionality, the new IC also features a high-speed data encryption/decryption engine, offering high security without impairing the high-speed performance of USB 3.0.

Today, PCs and digital audio-visual equipment handle an ever-growing volume of data such as digital photos, audio and video files. These market needs are driving storage devices, such as hard disk drives, to have ever-increasing data volumes and speeds.

The ubiquitous USB interface, used widely in external hard drives and USB memory sticks, has had a slow maximum data transfer rate of 480Mbps under the USB 2.0 specification, too slow to meet current strong demand for the ability to read and write high volumes of data in shorter time. The USB 3.0 specification (SuperSpeed USB) ratified in November 2008 resolves this issue by providing a maximum data transfer rate that is over 10 times faster than that of USB 2.0. In addition, this revolutionary next-generation specification includes greater protocol efficiency as well as improved power management techniques, which enable lower power consumption.

As this IC series enables 5Gbps high-speed data transfer between the PC and external HDDs, for the case of 3.5-HDDs, copying two hours worth of full high-vision video can be reduced from 12 minutes to approximately 3 minutes 30 seconds to 4 minutes in comparison to USB 2.0

The MB86C30A IC also contains an embedded AES encr
