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 I²C serial bus. This modular
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 I²C
serial interface specification. It is also compliant with the USB
Human Input Device and Monitor Control Class specifications.
