PDIUSBD11

INTEGRATED CIRCUITS PDIUSBD11 USB device with serial interface Product specification Supersedes data of 1999 Nov 19 1999 Jul 22 Philips Semiconductors Philips Semiconductors Product specification USB device with serial interface PDIUSBD11 FEATURES Complies with the Universal Serial Bus specification Rev. 1.1 Complies with the ACPI, OnNOW, and USB power management requirements 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 ...
