The OXU3100 is a low power storage controller bridging between USB
SuperSpeed 3.0 and a SATA hard disk.
Fully compliant with the USB 3.0 Specification, the OXU3100 is optimized for
bus-powered applications and supports a number of power saving modes,
including SATA Interface Power Management (IPM), which allows additional
power saving when connected to an HDD that also supports IPM.
The OXU3100 is a highly integrated device and requires a minimum number of
external components. Embedded in the device are a USB 3.0 / 2.0 PHY and
device controller, SATA II PHY, internal voltage regulator and Pulse Width
Modulators (PWMs) for LED control. The OXU3100 requires only a single
external crystal.
The OXU3100 is supported by a comprehensive support package that includes
evaluation boards, reference designs, and software development kit.
USB SuperSpeed 3.0
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)
