FEATURES

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

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.

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.
