STMicroelectronics I/O Hub aims at automotive infotainment

September 15, 2010 | Christoph Hammerschmidt | 222901076
STMicroelectronics has unveiled details of its I/O Hub (IOH) specifically designed to work with the Intel Atom processor E6xx series in automotive In-Vehicle Infotainment (IVI) systems.

Called ConneXt, the device connects to the Intel Atom processor E6xx series (formerly codenamed Tunnel Creek) using the industry-standard PCI Express (PCIe) interconnection technology. The purpose of the device is to enable richer experiences for car occupants. For example, a typical next-generation system will simultaneously provide the driver with applications such as 3D navigation and hands-free cell phone use, while the passengers are using the Internet or playing games on different, multiple displays.

STMicroelectronics claims that the ConnecXt IOH support for the Intel Atom processor E6xx series simplifies system design, enabling the use of open, off-the shelf software, and reducing development costs and time-to-market. In addition, it will provide rich I/O connectivity, including Ethernet AVB (Audio Video Bridging), CAN (Controller Area Network) and MOST (Media Oriented Systems Transport), as well as general purpose I/Os such as SATA (Serial Advanced Technology Attachment) and USB On-the-Go for broader applications.

“The Intel Atom processor E6xx series is more integrated and provides an open interface that allows it to be easily customized for in-vehicle infotainment solutions,” said Jonathan Luse, director of marketing for the Intel Low Power Embedded Products Division.  “Pairing it with an IOH such as STMicroelectronics' ConneXt allows our automotive customers to quickly develop a solid hardware platform to add compelling in-vehicle applications and services.”

The ConneXt chip was designed by ST in consultation with Intel to ensure that the IOH would be optimally matched to the Intel Atom processor E6xx series to expand its connectivity. First samples are scheduled for May 2011 and the expected high-volume price is approximately US$7.50.
