Langen, Germany - Fujitsu Microelectronics Europe (FME) has launched the MB86C30A, one of the first available USB 3.0 to SATA bridge ICs. The MB86C30A supports the ultra-fast 5Gbps maximum data transfer rate of SuperSpeed USB, the USB 3.0 specification.
The MB86C30 is the first in Fujitsu's new MB86C30 Series of USB 3.0 to SATA bridge ICs. When embedded in PC peripheral devices, the IC provides an order of magnitude increase in data transfer rates from external storage devices, such as hard disk drives (HDDs), to PCs, in comparison to the USB 2.0 specification.
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.
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 next generation specification includes greater protocol efficiency as well as improved power management techniques, which enable lower power consumption.
The MB86C30A is a single-chip solution that integrates all the USB signal communication control circuits, SATA communication control circuits, protocol and command control circuits that are the necessary functions for constructing an external USB storage device and to realize 5Gbps data transfer to a host PC.
The device also contains an embedded AES engine that supports two operation modes: Cipher Block Chaining (CBC), a mode for encrypting block data; and XTS, the XEX encryption mode with tweak and ciphertext stealing. Both modes are ideal for hard disks in terms of security, strength and speed of encryption/decryption.
The encryption engine makes it possible to store encrypted data on HDDs, thus protecting confidential information from threats when portable devices are lost or stolen " a well-publicized problem in recent years " or to prevent data leaks when storage devices are disposed of. Also, compared to software encryption, this hardware encryption does not burden the CPU of the host PC, and provides better protection of user's data.
The MB86C30A USB 3.0 to SATA bridge IC for PC peripherals is a single-chip solution that integrates the USB signal communication control circuits, SATA signal communication control circuits, protocol and command control circuits, and Fujitsu proprietary high-speed serial interface technologies, thus enabling 5Gbps high-speed data transfer. The 5Gbps maximum transfer rate of USB 3.0 allows a two hour Full HD video to be copied to a 3.5-inch hard disk drive in three to four minutes.
The new IC features an AES encryption / decryption engine, which eliminates the need for encryption software and an encryption / decryption IC. This makes it possible to encode data stored on external storage HDDs featuring standard SATA HDD, widely used for PCs and other related products.
The IC supports data transfer speeds that can cover SATA HDD performance, allowing protection of customer data with the same operation and usability of external storage HDD that do not support encryption. High-speed encryption and decryption processing at a maximum of 300MB/s, provides throughput without impairing the speed performance of USB 3.0.
The new IC integrates both USB 3.0 and USB 2.0 SATA links and PHYs and a 32-bit RISC processor to respond to requests from the USB host. Further features include SPI support for serial flash ROM, support for HID class, ATA/ATAPI device support, ATA command pass through function support, customised function support " VID/PID etc., low power consumption and a supply voltage of 1.2V " 3.3V.
The MB86C30 series is being jointly developed with Fujitsu Laboratories Limited and Fujitsu LSI Solutions Limited, whose extensive expertise and technologies for high-speed interfaces have been instrumental in realizing this IC. Going forward, Fujitsu Microelectronics will strengthen and expand the line-up of USB 3.0 standard products for storage devices.
The MB86C30A is manufactured in a 64-pin LQFP measuring 7 x 7mm (0.4mm pitch) using Fujitsu's 65nm low power CMOS process technology. The first engineering samples will be available in August 2009.
