Fast, Compact MB86C31 Series Now Included on the Integrators List for SuperSpeed USB Peripheral Silicon

Fujitsu Semiconductor America announced that the latest series of the Fujitsu USB 3.0-SATA bridge IC, the MB86C31, has passed USB-IF compliance testing conducted by the USB Implementers Forum and is now certified as compliant with the USB 3.0 SuperSpeed standard.

The Fujitsu MB86C31 USB 3.0-SATA bridge IC builds on the functionality of the MB86C30 series released last year. Key new features include support for the state-of-the-art UAS (USB attached SCSI) protocol, Native Command Queuing (NCQ) functionality, and hot-plugging of ATA devices. Other enhancements include improved USB PHY connectivity and lower power consumption as well as support for PWM and plural SPI devices. The MB86C31 is available in two small packages – a 64-pin LQFP (7mm x 7mm) and a 48-pin QFN (6mm x 6mm) – for greater flexibility.

With its enhanced features, available high-speed encryption hardware and data-transfer rates up to 5Gbps, the MB86C31 USB 3.0-SATA bridge IC series is a robust solution to enable secure, reliable, and super-fast connectivity between host PCs and external SATA storage devices such as HDDs, SSDs, and Blu-ray drives.

“SuperSpeed USB offers compelling advancements to the popular USB technology, and we’re excited to witness the growing momentum behind SuperSpeed USB technology,” stated Jeff Ravencraft, president and chairman, USB-IF. “The hard work of manufacturers bringing certified SuperSpeed USB products to market is a clear indication of strong industry support for SuperSpeed USB.” Read the rest of this entry »


Advanced Analogic Technologies introduced the AAT3698, a single input 1.6A linear charger with 28V input protection and 50mA low dropout (LDO) to manage the charging, sequencing and protection of Lithium (Li)-Ion and Lithium Polymer-powered portable devices. Targeting portable electronic devices including cellular phones, GPS navigation systems, portable media players and general hand-held consumer devices, the AAT3698 incorporates key safety features that adjust for excessive temperature or voltage, up to 28V, to avoid over-charging or other damage to the battery during charging.

“Lithium-Ion and Lithium-Polymer batteries are nearly synonymous with today’s portable electronic devices,” said Roger Smullen, product marketing manager at AnalogicTech. “A device’s ability to maximize its battery life and charging speed, while minimizing power loss is a critical consideration to its acceptance in the consumer marketplace. The AAT3698 is able to deliver these performance characteristics through USB connectivity or an AC adapter, giving designers even more options to enable broad adoption.”

Part of AnalogicTech’s Battery Manager(TM) Total Power Management IC(TM) (TPMIC(TM)) product family, the AAT3698 is a linear battery charger IC developed for single-cell Lithium (Li)-Ion and Li-Polymer batteries. Able to manage input voltage of up to 7V the IC integrates many features to increase design flexibility and facilitate design-in. Among these features are a 5V/50mA LDO that can provide additional power to an external device such as a radio in a wireless-communication product. This regulator is enabled at all times regardless of the status of the charger and is protected by an over-voltage protection (OVP) switch.

The AAT3698 is a small standalone charger solution that requires only 2 resistors and 4 small capacitors to operate and comes in a small, lead-free 14-pin 4 mm x 4 mm thin quad flat no-lead (TQFN) package. The AAT3698 precisely regulates battery voltage for Li-Ion/Polymer battery cells through a low RDS (ON) switch after it has reached 4.2V. The charging current can be set by an external resistor up to 1.6A.

Besides the IC’s built-in OVP circuit that helps prevent damage to the battery and the charging circuitry, other fault conditions are monitored in real time. In case of an over-current, battery over-voltage, short circuit, or over-temperature failure, the device will automatically shut down, thereby protecting the charging device, control system, and the battery under charge. A status monitoring output pin (STAT) is provided to indicate charging activity. This open drain output pin can be used to drive an external LED as a charging indicator. When the battery voltage has reached the constant voltage level, the AAT3698 has two charge termination and recharge modes— one controlled by the charger (AAT3698-1) and one where charge termination and recharge is managed by the host (AAT3698-2).

Eight New USB Devices Offer Enhanced Digital Functionality and Simultaneous Sampling Options

National Instruments announced NI X Series multifunction data acquisition (DAQ) devices for USB. USB X Series devices integrate high-performance analog measurement and control channels, digital I/O and counter/timers onto a single plug-and-play device, which engineers and scientists can use for a wide variety of portable test, measurement and data-logging applications. USB X Series DAQ devices include up to 32 analog inputs, four analog outputs, 48 digital I/O lines and four counters. The eight new devices range from 500 kS/s multiplexed AI to 2 MS/s/channel simultaneous sampling AI.

NI LabVIEW graphical programming makes it easy for engineers and scientists to develop completely custom test and measurement applications for USB X Series using intuitive graphical icons and wires that resemble a flowchart. LabVIEW 2010 simplifies data logging and analysis with a new technical data management streaming option within the NI DAQ Assistant and the ability to export data from a waveform graph to Microsoft Excel or NI DIAdem for post processing. USB X Series devices use the same multithreaded NI-DAQmx driver software as other National Instruments DAQ devices, making it easy to port LabVIEW or text-based code from previous applications for use with X Series.

USB X Series devices include two key technologies that make them as powerful as they are easy to use: NI-STC3 technology for advanced timing and triggering and NI Signal Streaming for high-speed, bi-directional data streaming. Read the rest of this entry »


LaCie announced the LaCie XtremKey – offering industrial-strength protection for your data. With capacities up to 64GB and an impenetrable shell, the XtremKey is a truly rugged USB key that stands up to the elements.

LaCie, originator of the flat, award-winning key-shaped USB flash drives, shields the XtremKey’s premium flash memory modules inside a 2mm metal pipe casing. Sealed with wear-resistant screw threads and a rubber O-ring, it is watertight up to 100 meters.

LucidPort Ships Second Generation USB 3.0 to SATA Bridge

LucidPort Technology released the USB302, a second generation USB 3.0 to SATA-II bridge designed for external USB storage devices. Following in the footsteps of the industry’s first USB 3.0 device, the LucidPort USB300, the USB302 is physically smaller and consumes less power than any other chip of its kind. Its support for USB Attached SCSI Protocol (UASP) allows it to run 20 to 100% faster than comparable USB 3.0 drives that use legacy mass storage drivers.

The UASP standard was developed by the USB-IF to enhance the efficiency of USB storage devices. It delivers faster and more consistent performance while lowering CPU utilization. “The market expects USB 3.0 to be fast,” said Reid Augustin, VP of Product Development at LucidPort. “UASP makes this a reality by running external USB drives as fast as, or even faster than drives connected directly to the motherboard.”

The USB302 is highly configurable and supports many premium features. These include automatic fan control, automatic standby timer, write protection, one touch backup, a safe power down button, Blu-ray drive support, and various activity and free space indicators. The USB302 keeps total BOM costs low by requiring only a single voltage (3.3V) and a single clock source (30 MHz).

The USB302 is shipping now and available in a 48 pin (6×6 mm) QFN package.
