Freescale Semiconductor's MPC5567 microcontroller (MCU) based on the PowerPC core enables fault-tolerant communication at high bandwidth rates of 10Mbps, reducing system cost by integrating maximum functionality on the chip. This device is said to be the first 32bit flash-based MCU with the FlexRay protocol. It is expected to be used in high-end automotive integrated chassis applications, as well as engine management and control for maximum performance and efficiency.

The MCU coordinates and controls communication and activities between various systems in the vehicle. For example, the MPC5567's integrated FlexRay functionality is designed to enable the integrated chassis control module to communicate in a quick, deterministic and dependable manner with other electronic modules based on the FlexRay protocol in the car. This helps provide increased performance and safety in braking, stability and suspension systems.

"FlexRay is gaining international support within the automotive industry and will be used by vehicle makers to enable exciting new safety-critical and performance features, as well as making on-board networking of existing electronics systems more robust," said Chris Webber, vice president of the Automotive Practice at Strategy Analytics. "Integrating a 32-bit core, 2MB of embedded flash and a FlexRay controller is important in giving designers the opportunity to increase performance and functionality while reducing cost and board space."

FlexRay founders Freescale, Philips, BMW and DaimlerChrysler have been working together since 2000 to help speed the adoption of FlexRay, a communications protocol designed to handle the growing number of digital elements that make up a 21st century automobile. Over the past two years, additional automotive companies, such as Bosch, General Motors, Ford, Volkswagen, Audi and Siemens VDO, have joined these leaders in an effort to make FlexRay the de facto standard for advanced applications in the automotive industry. Today, more than 80 companies from the automotive, semiconductor and software industries support the FlexRay standard. FlexRay-enabled vehicles are expected to hit the market in 2006.

The MPC5567 is available now in sample quantities. Pricing was not released. The MPC5567EVB evaluation board is available now in sample quantities.
