V850E/CAG4-M
32-Bit Single-Chip Microcontroller
DESCRIPTION
This device is a new, powerful NEC 32-bit RISC microcontroller with embedded FlexRay communica-
tion interface. With its high performance, large memory size and fully-fledged communication inter-
faces it is especially well suited for high end gateway and other body applications in the automotive
area. This microcontroller extends the widely used NEC V850 family into the high performance range
and supports with its FlexRay interface and the MediaLB™ interface the upcoming new standards for
communication inside automotive.It is optimized for gateway applications featuring control of up to 6
CAN as standard interfaces in the automotive area. With the embedded MediaLB™ interface this
device opens a new possibility to connect to the MOST® world, offering a very high data throughput
espc. for asynchronous data transfer. The Timer structure is suitable for most body applications by
offering high number of input capture and PWM outputs. The new Multi LIN Master macro can connect
all 6 LIN channel in a very efficient way, with a minimum CPU interaction. With these features the
device fits also to many body applications.
