Trends in Road TrafficDeaths

Electronic Market Growth Dynamics:1. New systems are introduced in high end vehicles based on consumer demand for safety.2. Government safety regulations are changed to mandate the new system.3. Increasing legislation for safety systems (TPMS, ESP) is driving the Adoption of electronic braking, and safety

systems around the world.4. ADAS, Radar and Camera systems expected to be next for mandate.


“As more electronic sensors and computing capability are incorporated into modern vehicles, the vehicle manufactures now have the technology to enhance safety in a way that was impossible a decade ago. We believe that many of these technologies can detect and compensate for driver errors such as inattention, drowsiness, or driver misjudgment.”

Understanding Safety-Critical Dual Core Microcontroller

Interactive tutorial available online athttp://www.freescale.com/automotive

In the training and event section

► The tutorial enables the user to investigate how dual-core MCU architecture behaves in the presence of fault conditions.

► The demonstration allows the user to configure hardware and software modes and simulate the architecture response when a failure occurs in the system.

FTF 2010 Special:See the demo at the tech lab!


Continental Press Release, November 2009Continental has received a safety certification according to the IEC 61508 SIL-3 standard for a chipset used as brake controller [...]The chipset in question consists of a SPACEmicrocontroller and a PCU mixed-signal chip.

Proof Point: Effective Cooperation on Functional Safety

Freescale Press Release, October 2007Freescale and Continental collaborate on multi-core 32-bit microcontroller for electronic braking systems [...] The SPACE device integrates three e200 cores based on Power Architecture® technology, making it the industry's first triple-core automotive MCU.
