Elan introduces miniature USB host controller chip

An Elan Digital Systems product story

Edited by the Electronicstalk editorial team Oct 22, 2009

Elan Digital Systems has launched a 4 x 4mm USB host controller chip in a 36-pin QFN package with a low power consumption of less than 10uW standby.

The USBHC869 is designed to provide a cost-effective solution for designers who need to add one or more USB ports to virtually any 8- or 16-bit processor systems.

The design supports data transfer speeds of up to 10Mb/s without the need for DMA support from the host processor.

The device supports 1.8/2.8V 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 on the company's VMB5000-series devices, which have already been adopted worldwide for mobile communications products and which incorporate elements of Elan's patented design.

A development board and full documentation are available, including driver design information.

Software development is also available direct from the company.
