Automotive MCU enables park assist and blind-spot detection

Compared to the previous method of broadcasting uncompressed video data over LVDS cabling, BroadR-Reach technology—in which compressed video is transmitted via unshielded single twisted-pair cable—reduces the costs for connectivity by 80 per cent and cable weight by 30 per cent, according to Broadcom's estimates.

These cost and weight reductions are expected to help carmakers add surround-view camera systems to higher volume, mid-range and economy vehicles.

Beyond reducing costs for connectivity and cable weight, the Qorivva MPC5606E helps reduce the size of automotive camera modules by up to 50 per cent.

McAuslin pointed out that camera size is becoming more important to automotive OEMS. Carmakers want peripheral cameras to be small and unobtrusive for aesthetic reasons. Smaller cameras can be "more easily hidden within design features of the car, such as a front grill, bumper or wing mirror," Freescale explained.

With the Qurivva MPC5606E, what used to be dual-chip solution (Freescale's MCU and Broadcom's BroadR-Reach phy) has become a single chip. The MCU and the PHY are integrated in system-in-package through stacked die wire bond. The chip is now available in a small, low-cost 8mm x 8mm package, according to Freescale.

Key features included in the Qurivva MPC5606E—designed for real-time broadcast of video and audio data over Ethernet—are image compression through a Motion-JPEG encoder, precision-time stamping hardware (IEEE 1588), Fast Ethernet controller, and a BroadR-Reach physical layer for Ethernet broadcast.

The chip, currently available for lead customers, will be qualified in June, 2014. It will be in volume production by the end of 2014, McAuslin added. Vehicles integrated with the new Qorivva MPC5606E will reach the market in 2015.
