Freescale and Broadcom partner on compact, integrated microcontroller and PHY solution for 360˚ on-board camera systems
Freescale Semiconductor and Broadcom Corporation have partnered to create Freescale’s Qorivva MPC5606E—the first fully-integrated, packaged microcontroller (MCU) and physical layer transceiver (PHY) solution for use in 360-degree automotive camera systems.
Advanced Driver Assistance Systems (ADAS) are quickly growing in popularity among consumers, driven in large part by a strong affinity for the functionality enabled by surround view cameras such as park assist and blind spot detection. According to ABI Research, Inc, the global ADAS market is forecast to reach US$261 billion by 2020, establishing ADAS as one of the fastest growing segments in the automotive sector.
Camera size is increasingly important to automotive OEMS, as manufacturers prefer peripheral cameras to be miniaturized and unobtrusive to maintain vehicle aesthetics. Smaller cameras can be more easily hidden within design features of the car, such as a front grill, bumper or wing mirror.
Featuring a compact 8x8mm package, the Qorivva MPC5606E device is designed to reduce the size of automotive camera modules by up to 50%, while helping speed time to market and reduce the overall bill-of-material.
Fundamental to the size and performance advantages of the Qorivva MPC5606E is the incorporation of Broadcom’s BroadR-Reach automotive Ethernet PHY. The integrated Ethernet solution enables compact vision compression and rapid transmission of video data throughout the vehicle.
Ethernet has emerged as a mainstream automotive network technology, allowing multiple in-vehicle systems to simultaneously access information over a single unshielded twisted pair cable at speeds of up to 100 Mbps. By eliminating cumbersome, shielded cabling, automotive manufacturers can reduce connectivity costs up to 80% and cabling weight up to 30%, according to Broadcom.
By leveraging Ethernet, a proven lower-cost, automotive-qualified solution for secure transmission of in-vehicle data, the next step is to make the technology even more attractive by enabling ADAS system integrators to dramatically reduce the footprint of their solutions. Our collaboration with Broadcom resulted in a single, small-footprint solution that combines the image compression features of our Qorivva MPC5606E device with the time stamping and high performance transmission capabilities of the BroadR-Reach PHY.—Davide Santo, Safety and Chassis Operations Manager for Freescale’s Automotive MCU Group
Freescale and Broadcom are both founding members of the OPEN Alliance Automotive Special Interest Group (SIG) (One-Pair Ethernet). The OPEN SIG is a non-profit industry alliance of automotive and tech industry leaders dedicated to establishing Ethernet as the networking technology of choice in automotive infotainment and ADAS applications. Together with major car makers and global electronic suppliers, Freescale and Broadcom are committed to the promotion of BroadR-Reach as the industry standard interface for automotive Ethernet.
The Qorivva MPC5606E MCU features:
- 64MHz core built on Power Architecture technology
- 512K Flash and 96K SRAM
- Image compression through a Motion-JPEG encoder
- IEEE1588 module for time stamping
- BCM89810 BroadR-Reach PHY
- 8x8mm MAPBGA package with 121 balls
