Freescale and Broadcom Shrink their Ethernet MCU
April 2, 2014 by John Day
Freescale Semiconductor and Broadcom Corporation together launched the Freescale Qorivva MPC5606E, a single-chip microcontroller (MCU) that integrates the Broadcom BroadR-Reach PHY. Its predecessor, the dual-chip MPC5604E, is currently in production. Freescale is sampling the new device now and expects that will be available in production quantities by the end of 2014.
Among other applications the device targets 360-degree “surround view” camera systems, which are used in applications such as park assist and blind spot detection. Automotive OEMS 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.
50% Size Reduction; Fast Video Data Transmission
The 8x8mm Qorivva MPC5606E is designed to reduce the size of automotive camera modules by up to 50 percent, while helping speed time to market and reduce the overall bill-of-material. The integrated Ethernet solution, Broadcom’s BroadR-Reach® automotive Ethernet PHY, enables compact vision compression and rapid transmission of video data throughout the vehicle.
Less Weight, Lower Cost
In contrast, the firms said, existing applications broadcast uncompressed video data over expensive screened LVDS (low voltage differential signaling) cabling versus unshielded twisted pair cabling. Cabling weight can be reduced by as much as 30 percent and connectivity costs reduced by up to 80 percent.
Freescale and Broadcom are charter members of the Open Alliance (One Pair Ether Net) Automotive Special Interest Group (SIG) , which encourages wide scale adoption of Ethernet-based networks as the standard in automotive networking applications.
Freescale and Broadcom are committed to the promotion of BroadR-Reach® as the industry standard interface for automotive Ethernet.
Advanced Features Beyond the Luxury Class
“Demand for our BroadR-Reach technology continues to rise as automakers embrace the inherent advantages that Ethernet has to offer,” said Dr. Ali Abaye, Broadcom Senior Director of Automotive. “Our collaboration with Freescale will enable the development of more optimized ADAS (Advanced Driver Assistance System) camera solutions and drive the proliferation of advanced features in a broader range of vehicles – beyond the luxury class.”
“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,” said Davide Santo, Safety and Chassis Operations Manager for Freescale’s Automotive MCU Group.
“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.”
Advanced Driver Assistance Systems (ADAS) are quickly growing in popularity among consumers. 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.
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
Broadcom’s BroadR-Reach automotive-qualified portfolio has met global automotive industry requirements including TS16949 compliance/ISO 9001 certification, in-car EMC performance and AEC-Q100 qualification.
Development tools include a MPC5606E evaluation board, Ethernet streaming software, camera application software, and an AUTOSAR RTOS (real-time operating system).
