PDIUSBD11; USB device with serial interface
| Description |  |
|
The Universal Serial Bus hub PDIUSBD11 is a cost and
feature-optimized USB interface device. It is used in
microcontroller-based systems and communicates with the system
microcontroller over the high speed I²C serial bus. This modular
approach to implementing USB functions allows the designer to
choose the optimum system microcontroller from the available wide
variety. This flexibility cuts down the development time, risks, and
costs by allowing the use of the existing architecture and the
firmware investments. This results in the fastest way to develop the
most cost-effective USB peripheral solutions. The PDIUSBD11 is
ideally suited for computer monitors, docking stations, keyboards,
and many other applications that use the I²C or the SMBus-based
architecture.
The PDIUSBD11 conforms to the USB specification Rev. 1.1, I²C
serial interface and the SMBus specifications. It is fully compliant
with the Human Interface Device Class and Monitor Control Class
specifications. Its low suspend power consumption along with the
programmable LazyClock output allows for easy implementation of
equipment that is compliant to the ACPI, OnNOW, and USB power
management requirements. The low operating power allows the
implementation of bus-powered function.
The PDIUSBD11 is fully backward compatible to the
PDIUSBH11/PDIUSBH11A software. In addition, it also incorporates
the feature enhancements like SoftConnectTM, LazyClock,
programmable clock output, lower frequency crystal oscillator,
multiple function endpoints and integration of termination resistors.
All of these feature enhancements contribute to significant cost
savings in the system implementation and at the same time ease the
implementation of advanced USB functionality into the peripherals.
