Car MCUs leverage Power Architecture

The MCUs will be built using a 55nm non-volatile memory (NVM) process for improved power efficiency. They will be available in early 2012.

Freescale says 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.

Thus, Freescale's MCUs are built with multiple cores to help build redundancy into the system for fault monitoring and distributed control that is required by safety-critical applications.

The Qorivva MCUs include configurable peripheral sets such as flexible timers and motor control systems. DSP capabilities provide additional functionality. Faster processing speeds allow more complex control algorithms and features and increased on-chip memory content (flash and RAM) to eliminate 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.
