OXU3100, USB SuperSpeed 3.0 to SATA Controller Highlights The OXU3100 is a low power storage controller bridging between USB SuperSpeed 3.0 and a SATA hard disk. General Features o USB SuperSpeed 3.0 to SATA storage controller Fully compliant with the USB 3.0 Specification, the OXU3100 is optimized for bus-powered applications and supports a number of power saving modes, Key Features including SATA Interface Power Management (IPM), which allows additional o USB 3.0 to SATA storage power saving when connected to an HDD that also supports IPM. controller o Integrated USB 3.0 / USB 2.0 PHY o Integrated SATA II compliant core and PHY - Supports 3.0Gbps and 1.5Gbps interfaces o Support for UAS/UASP (USB attached SCSI Protocol) delivering maximum throughput o Support for BOT (Bulk only Transport) o Support for USB Mass Storage Class The OXU3100 is a highly integrated device and requires a minimum number of o SPI interface for serial flash external components. Embedded in the device are a USB 3.0 / 2.0 PHY and o Secondary SPI for simple interface device controller, SATA II PHY, internal voltage regulator and Pulse Width to external system components Modulators (PWMs) for LED control. The OXU3100 requires only a single such as LCD display external crystal. o 9 GPIOs allow easy product customization The OXU3100 is supported by a comprehensive support package that includes o In-field update of firmware via evaluation boards, reference designs, and software development kit. USB o 3.3V supply voltage - Internal regulator for core USB SuperSpeed 3.0 voltage The embedded USB 3.0 PHY supports SuperSpeed, High Speed and Full Speed modes, using either bulk-only transport Mass Storage Class device protocol or the new USB Attached SCSI Protocol (UASP). Its fast read and write transfers ensure that the maximum possible host performance is maintained. SATA Interface The embedded 3GHz SATA host interfaces supports the latest revisions of the SATA II specifications. Interface speeds of 3GHz and 1.5GHz deliver maximum performance with minimum latency for external SATA storage. Power Management The OXU3100 provides OEMs with a range of power saving modes to ensure minimal power consumption in all configurations, including: o USB 3.0 U0 U3 power states o USB 2.0 standby / suspend states o SATA Interface Power Management (IPM) PLX Technology, www.plxtech.com Page 1 of 2 6/18/2010, Version 2.0 OXU3100, USB SuperSpeed 3.0 to SATA Controller Embedded Processor Development Support The on-chip RISC processor enables a whole new series of For external PC storage solutions, PLX Technology offers standalone consumer electronic product to be developed in a comprehensive support package including: a simple C programming environment. o Reference designs comprising both hardware and software components o Evaluation boards with pre-built application firmware o Software Development Kit (SDK) comprising source code and debug boards o Extensive range of application notes to shorten learning curves and simplify implementation Product Ordering Information Part Number Description OXU3100- AANC G USB3.0 to SATA controller OXU3100 Block Diagram PLX Technology, Inc.
