Elan Digital Claims Smallest off-the-shelf USB Host Controller Chip
Elan Digital Systems is launching a tiny USB Host Controller chip which measures just 4x4mm 36 pin QFN with low power consumption of <10uW standby. This chip is believed to be the smallest of its kind in the market today. The new USBHC869 is designed to provide an easy and cost-effective solution to designers who need to add one or more USB ports to virtually any 8 or 16 bit processor systems.
A unique feature of the design is that it supports data transfer speeds of up to 10 Mb/s without the need for DMA support from the host processor which removes a major design headache in many systems.The device supports 1.8/2.8 and 3.3v signalling.
Potential cost-saving and design simplification is achieved via an internal Phase Lock Loop which allows the use of an external clock input such as the main system clock.
The USBHC869 is based upon Elan's highly successful VMB5000 series devices which have already been widely adopted worldwide for mobile communications products and which incorporate elements of Elan's patented design.
A development board and full documentation is available, including driver design information. Software development is also available direct from Elan Digital Systems.
