Electronica, Munich –

As the Automotive Forum at the Munich Messe got underway today Freescale Semiconductor launched the Qorivva microcontroller families, based on Power Architecture technology, and designed to increase performance, safety and energy efficiency for a new generation of smart vehicles.
The MCUs are to be built using a 55 nanometer (nm) non-volatile memory (NVM) process for improved power efficiency but will not be available till early 2012.
Freescale say the increasing complexity of automotive electronic systems is leading to rapidly increasing requirements for MCU performance, making multicore processing a necessity for both safety and performance. Safety mandates around the world continue to increase, with many requiring fault-recognition systems and even fault tolerance, for braking, steering, powertrain and some of the latest advanced driver assistance systems.
At the same time, as complexity continues to grow, reducing power consumption is quickly becoming critical, as up to 100+ electronic control units require current to function within the vehicle. Now more than ever, Freescale is a technology partner and supplier the auto industry can turn to for innovative solutions that meet their performance, efficiency, reliability, quality and cost objectives.
To help automakers build the safest cars on the road Freescale is introducing MCUs with multiple cores to help build redundancy into the system for the fault monitoring and distributed control required by safety-critical applications.

Qorivva MCUs include configurable peripheral sets such as flexible timers and motor control systems.

Digital signal processing capabilities provide additional functionality.

The Qorivva MCUs have increased processing speeds that allow more complex control algorithms and features and increased on-chip memory content (flash and RAM) to reduce the need for off-chip memory. Intelligent peripheral sets are included to drive complex control systems, such as transmission solenoids, complex injectors and electric motors, with minimal overhead from the microprocessor core while improved, embedded sensor interfaces to allow simple connection to next-generation automotive sensors.
Higher speed analog-to-digital converters are used to meet the differing needs of the latest interfaces.
A Qorivva body and security family has low power consumption for ‘always on’ systems; advanced vehicle networking with full connectivity offerings (LIN, CAN, MOST, FlexRay™ and Ethernet); and encryption for advanced vehicle network security.
A safety and chassis family includes multicore advanced safety architecture with fault monitoring and event recording, as well as correction systems, for maximum protection, building toward the future fault-tolerant systems needed for fully autonomous vehicles
A powertrain and hybrid family has high-performance multicore MCUs with advanced motor control peripherals for hybrid vehicles and high-precision analogue interfaces and digital communications links to analog sensors.

To meet the requirements of next-generation powertrain systems, many devices in this family will also feature Freescale’s advanced safety architecture.

Each 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 compiler support and multicore debuggers from the company’s development partners and Freescale’s CodeWarrior tool set.

Freescale is a founding member of the DSI, 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 system labs and software customisation services.
