PDIUSBH11中文资料飞利浦数据手册PDF规格书

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.
