產品概觀

The V850E/Sx3-H are 32-bit single-chip microcontrollers that include the V850E1 CPU core and peripheral functions such as ROM/RAM, a timer/counter, serial interfaces, an A/D converter, and a D/A converter. The V850E/Sx3-H include an IEBusTM (Inter Equipment BusTM) controller for the automotive LAN, and some of the models also include a CAN (Controller Area Network) controller and enable extremely high cost performance for automotive use multimedia equipment such as car audio systems.
