NEC Electronics Europe has announced a new MCU for automotive body applications. The V850E/CAG4-M is a member of NEC Electronics' 32bit RISC MCU family with embedded FlexRay interface. Offering high performance, large memory and full-fledged communication interfaces, it is especially suited for high-end gateway and other body applications.

The V850E/CAG4-M extends the V850 32bit MCU family into the high-performance range, with the FlexRay and MediaLB interfaces supporting emerging standards for communication within automotive applications.

The MCU is capable of controlling up to six CAN interfaces, and is optimized for automotive body applications like gateways. The device's embedded MediaLB interface provides connectivity to the MOST world, offering very high data throughput, especially for asynchronous data transfer. Dedicated motor control, real-time clock features and power-saving modes come into their own in body applications, as does the timer structure with various input capture and PWM output channels.

The Multi-LIN master macro can connect all six LIN channels very efficiently, with minimum CPU interaction. The FPU and 80MHz RISC performance also make the V850E/CAG4-M an attractive proposition for new fields such as diagnostics and high-end server concepts.

V850E/CAG4-M samples are scheduled for January 2008, with volume production due in early 2009.
