Bangalore: Fujitsu Microelectronics has announced the launch of USB 3.0-SATA bridge ICs for PC peripherals. It enables data transfer rates of 5Gbps maximum between external storage devices, such as hard disk drives (HDDs) and PCs. The 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.

The ubiquitous interface, used widely in external hard drives and USB memory sticks, has a slow maximum data transfer rate of 480Mbps under the USB 2.0 specification; hence there was need of faster data transfer speed. This 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 encryption engine that makes it possible to store encrypted data on HDDs, thus protecting confidential information from threats when portable devices are lost or stolen. In addition, compared to software encryption, this hardware encryption does not burden the CPU of the host PC while providing more secure protection of user's data.
