V850E/CAG4-M V850E/CAG4-M V850 series 32-bit RISC Microcontroller Preliminary Product Letter Description The V850E/CAG4-M V850E/CAG4-M is a new member of NEC's powerful 32-bit RISC microcontroller family with embedded FlexRay communication interface. Offering high performance, large memory size and fully-fledged communication interfaces, it is ideal for high-end gateway and other body applications in the automotive field. The V850E/CAG4-M V850E/CAG4-M takes the popular V850 family into the high-performance bracket and supports emerging standards in automotive communication with FlexRay and MediaLBTM interfaces. Applications The V850E/CAG4-M V850E/CAG4-M is optimized for automotive body applications like gateways, providing control of up to 6 CAN as standard interfaces. The embedded MediaLBTM interface opens a new way to connect to the MOST® world for very high data throughput especially for asynchronous data transfer. The timer structure is suitable for body applications in that it offers multiple input capture and PWM output channels as well as dedicated motor control. The multi-LIN master macro can connect all 6 LIN channels very efficiently, with minimum CPU interaction. With real-time clock and power-saving mode support, the device is right for many car body applications. The 16-bit parallel external bus interface allows the V850E/CAG4-M V850E/CAG4-M to connect to external components like RAM, while the FPU and 80 MHz RISC performance covers new fields of diagnostics and high-end server concepts. The device's internal window watchdog, parity on RAM, ECC on flash (single error correction, double error detection), CRC unit and FPU also support safety-relevant applications.
