Fujitsu Now Shipping USB 3.0-SATA Bridge IC for PC Peripherals Supporting SuperSpeed USB 3.0

MB86C30A incorporates USB and SATA signal communication control circuits, protocol and command control circuits with a high-speed encryption/decryption engine on a single device

Fujitsu Microelectronics America, Inc. (FMA) is now shipping its first generation USB 3.0-Serial ATA (SATA) bridge IC, built with Fujitsu’s own physical layer device (PHY). The new MB86C30A supports the ultra-fast 5Gbps maximum data-transfer rate of USB 3.0, and incorporates an encryption/decryption engine. Samples are being built using Fujitsu’s 65-nanometer low-power process technology, and are available now.

Compared with USB 2.0 connections, the MB86C30A bridge IC provides an order of magnitude increase in data transfer rates from external storage devices such as hard disk drives to PCs. The new bridge IC incorporates on a single chip the USB communication control circuits, SATA communication control circuits, and protocol control and command control circuits. These circuits are required to construct an external USB storage device and to realize 5Gbps data transfer to a host PC. (For an example of a system using the MB86C30A, visit this URL: http://www.fujitsu.com/downloads/MICRO/fma/pdf/USB30_SysEx.pdf.)

The MB86C30A IC also contains an embedded Advanced Encryption Standard (AES engine to protect confidential data from being stolen, unintentionally leaked or lost, and to protect data following the disposal of storage devices. Hardware encryption does not burden the CPU of the host PC, and provides optimal protection for data. The encryption/decryption engine enables data to be easily encrypted for secure storage in external devices such as hard disk drives without impairing the performance of USB 3.0.

“The new USB 3.0-SATA bridge IC provides customers with an innovative, reliable, optimized chip design in a small package. Pricing is competitive because we are using our own PHY and process technology,” said Davy Yoshida, director of business development of the Embedded Platform Solutions business group of Fujitsu Microelectronics America. “We expect our chip to be embedded in devices to be released by the end of this year.”

“Fujitsu has applied its extensive expertise in low-power CMOS technologies for high-speed interfaces including Fast Ethernet, Gigabit Ethernet, PCI-express, SATA and IEEE 1394. This IC is the first in the MB86C30 series, which was jointly developed with Fujitsu Laboratories Limited, utilizing their high-speed serial interface technologies, and Fujitsu LSI Solution Limited. Fujitsu Microelectronics plans to strengthen and expand its lineup of USB 3.0 standard products for storage devices.”

Features Full USB 3.0 Performance with Encryption Capabilities

Today, PCs and audio-visual equipment handle an expanding volume of data from digital photos to audio and video files, requiring storage devices to have increased volumes and speeds. The USB 2.0 interface, which is used widely in external hard drives and memory sticks, has had a maximum data transfer rate of 480Mbps. To provide faster speeds for reading and writing high volumes of data the USB 3.0 specification was ratified in November 2008. USB 3.0 supplies as much as 10 times the data transfer rate of USB 2.0, along with improved protocol efficiency and power management techniques. The maximum transfer rate of 5Gbps of USB 3.0 allows 10 to 30 GBytes of video data to be copied to a 3.5-inch hard disk drive in one-third to one-fourth the time USB 2.0 needs.

The MB86C30A bridge IC supports two AES 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. Three key lengths are supported – 128bit, 192bit and 256bit. High-speed encryption and decryption processing at a maximum of 300 MByte/sec. provides throughput without impairing the performance of USB 3.0.

The Fujitsu MB86C30A USB 3.0 external storage solution is a bridge IC that connects USB 3.0 and ATA/ATAPI devices. It delivers super-high-speed data transfer of up to 5Gbps between the host PC and SATA storage devices such as HDDs, SSDs, DVDs and CDs. The IC complies with Universal Serial Bus Specification 3.0 Revision 1.0 and is backward compatible with Universal Serial Bus Specification Revision 2.0. The MB86C30A bridge IC integrates SATA, USB links, PHYs, a high-performance 32-bit RISC processor, a hardwired encryption block, SRAM, and common interfaces to communicate and respond to requests from the USB host.

The Fujitsu MB86C30A features low power consumption and high-speed encryption hardware. In addition, the device supports both GPIO for design flexibility and SPI for interfacing to offchip serial Flash ROM.

Written by Administrator   

ImageMicrochip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced its next-generation low-power PIC® microcontroller (MCU) families with nanoWatt XLP™ eXtreme Low Power Technology for sleep currents as low as 20 nA. These three new 8- and 16-bit MCU families join three other recent 8-bit families that are all part of Microchip’s nanoWatt XLP portfolio, providing designers with a rich and compatible low-power migration path that includes on-chip peripherals for USB and mTouch™ sensing solutions. This industry-leading combination of low power consumption and functionality makes these PIC MCUs ideal for any battery-powered or power-constrained application.

 

 

 

“Microchip’s new nanoWatt XLP families of PIC microcontrollers have surpassed the competition by a substantial margin to offer a new industry benchmark for the lowest sleep current consumption,” said Tony Massimini, chief of technology at Semico Research Corporation. “When you factor in the integration of EEPROM, oscillators, USB and capacitive touch sensing peripherals, the potential reduction in system-level power consumption is quite substantial.”

Three of nanoWatt XLP Technology’s key advantages are: Sleep currents down to 20 nA, Real-Time Clock currents down to 500 nA, and Watchdog Timer currents down to 400 nA. The vast majority of low-power applications require one or more of these features. nanoWatt XLP Technology combines all three in a comprehensive portfolio of devices. Whether it is extended battery life, sealed batteries, or the integration of energy harvesting, Microchip’s 8- and 16-bit PIC MCUs with nanoWatt XLP Technology provide more freedom for designers that need their products to operate longer using less power, or requiring fewer battery changes.

“The extremely low sleep current and numerous wake-up features of Microchip’s new nanoWatt XLP microcontrollers should be ideal for battery-operated devices, which actually spend most of the time asleep,” said Tom Starnes, embedded processor analyst at the semiconductor research firm Objective Analysis. “The interest in the market for such low-power processors, for use in consumer to industrial applications, is really on the rise.”

The three new nanoWatt XLP MCU families that were announced today include the four-member, 16-bit PIC24F16KA family, which features typical sleep currents as low as 20 nA along with integrated EEPROM memory, and small-footprint and low pin count (20- and 28-pin) package options. Additionally, this family enables applications to run for more than 20 years from a single battery. The six-member PIC18F46J11 and the six-member PIC18F46J50 8-bit MCU families feature typical sleep currents of less than 20 nA. The general-purpose PIC18F46J11 MCUs provide up to 64 KB of Flash program memory and the peripheral set of a typical 64- or 80-pin device in only 28- or 44-pins; while the PIC18F46J50 devices add integrated Full-Speed USB 2.0 to enable connectivity for embedded applications requiring remote field upgrades or the downloading of data.

“Through significant investment in our new nanoWatt XLP Technology, which combines enhanced design techniques and new features, Microchip has driven power consumption to new lows, surpassing the industry and becoming the new leader in low-power microcontrollers,” said Mitch Obolsky, vice president of Microchip’s Advanced Microcontroller Architecture Division.

Numerous applications can benefit from the extreme low power and peripheral integration of the nanoWatt XLP MCUs. Examples include portable and battery-powered applications in the Consumer (sealed disposable electronics, portable electronics white goods, game controllers, digital photo frames, coffee machines); Industrial (energy harvesting/scavenging, utility meters, security systems, thermostats, sprinkler timers, portable temperature controllers, remote/portable gas sensors and remote sensor networks, data logging and asset tracking, sealed/harsh environment sensors); Automotive (diagnostic equipment, car alarms, key fobs); and Medical markets (home medical devices, oxygen/bio flow meters, digital thermometers, patient monitors, lifestyle/fitness monitors and pedometers).
