DESCRIPTION
The Philips Semiconductors PDIUSBH11 is a compound USB hub
IC (hub plus embedded function).
It is used in a microcontroller based system and communicates with
the system microcontroller over the I
approach to implementing a hub and embedded function allows the
designer to maintain the system microcontroller of choice and retain
existing architecture. This cuts down development time and offers
the most cost-effective solution.
Ideal applications for the IC include computer monitors and
keyboards.
The PDIUSBH11 conforms to the USB specification 1.0 and I
serial interface specification. It is also compliant with the USB
Human Input Device and Monitor Control Class specifications.
The embedded function of the PDIUSBH11 appears as PORT1 to
the host system and the four downstream ports are numbered 2
through 5.
