New 32-bit MCU family designed to make advanced driver assistance systems more affordable for a broad range of vehicles

The U.S. Insurance Institute for Highway Safety reports that one in three fatal passenger vehicle crashes and one in five serious or moderate injury crashes could have been avoided if more vehicles had been equipped with crash-avoidance technologies. Freescale Semiconductor’s cost-effective new family of Qorivva 32-bit microcontrollers (MCUs) is designed to help make advanced driver assistance systems more affordable and accessible for a broad range of vehicle models.

The Qorivva MPC567xK family of 32-bit MCUs, built on Power Architecture® technology, provides designers of automotive safety systems the ability to engineer advanced, yet economical, safety features, such as blind-spot detection, lane-departure warning systems, side view assistance and adaptive headlights. These and similar advanced automotive safety systems are part of the rapidly growing market known as advanced driver assistance systems (ADAS).

The Qorivva MPC567xK family helps reduce and, in many cases, eliminate the need for additional external signal processing components. With its high-throughput, dual-core architecture, high-density on-chip memory and optimized signal processing engines (SPE), the MPC567xK family delivers an affordable, compelling solution for the latest ADAS applications. The MPC567xK family uses a dual core implementation of the new Z7 Power Architecture CPU. This same core is used on the MPC5674F which recently achieved an unprecedented benchmark score of 305 Automarks™ in the Embedded Microprocessor Benchmark Consortium’s (EEMBC®) AutoBench™ suite of tests. Even in that single core configuration the Z7 demonstrated more than three times the performance of the previous highest score set by a competitor.

“Freescale’s Qorivva MPC567xK MCUs are a cost-effective way for automakers to help satisfy consumers seeking safer vehicles and meet global government regulations requiring better passenger protections,” said Ray Cornyn, director of Freescale’s Automotive MCU business. “This economical, scalable new MCU family, which is built on Power Architecture technology we’ve tailored specifically for the automotive market, allows us to deliver a competitive advantage for the global ADAS market and can help make vehicles safer around the world.”

Even with rapidly increasing global demand, the expense of ADAS components has sometimes made it difficult for automakers to incorporate the systems into the full range of their vehicle lineups. As a leading global supplier of automotive semiconductors, Freescale has developed a cost- and power-efficient solution to help lower the barriers to providing ADAS for all vehicles.

The 32-bit, dual-core MPC567xK MCUs include a lock-step mode to detect and mitigate common hardware and software faults while meeting automotive software integrity level D standards ahead of anticipated global legislative mandates for more active safety. Ideal for radar- and camera-based ADAS, the MPC567xK family operates at up to 180 MHz, with up to 2 MB flash memory and 512K SRAM.

Freescale announced the Qorivva line of 32-bit automotive MCUs in November 2010. In addition, the company announced the expansion of the Xtrinsic intelligent sensing portfolio with a 77 GHz silicon Germanium (siGe) chipset for intelligent radar technology. Freescale’s Qorivva MPC567xK family, in combination with its siGE products, allows it to address the core chipset for radar based ADAS solutions. With these innovations and more than 200 million 32-bit Power Architecture MCUs shipped to date, Freescale has proven itself as a trusted supplier of solutions for the automotive electronics market.

Comprehensive ecosystem for Qorivva MCUs
The strength and value of Qorivva microcontrollers extend beyond the silicon. Each Qorivva MCU comes with a full run-time software solution, including AUTOSAR MCAL driver suites and AUTOSAR real-time operating system for single-core and multicore MCUs. Qorivva MCUs also are supported by development tools, including high-performance compilers and multicore debuggers from Freescale development partners and Freescale’s CodeWarrior development studio.

Freescale’s deep roots in the automotive electronics industry are apparent in its involvement with industry consortia. Freescale is a founding member of the DSI, Power.org, FlexRay™ and LIN consortia, a premium member of AUTOSAR and an active member of the PSI5, JASPAR and GENIVI consortia. Freescale’s Power Architecture products are also supported by its global systems labs and software customization services.

Availability
Freescale plans to offer sample quantities of the first member of the MPC567xK family in March. General availability is planned for Q3 2011. For more information, visit www.freescale.com/automotive.
