The V850ES/SG3 and V850ES/SJ3 are 32-bit single-chip microcontrollers that includes the V850ES CPU core and peripheral functions such as ROM/RAM, a timer/counter, serial interfaces, an A/D converter, and a D/A converter. The V850ES/SG3 and V850ES/SJ3 includes an IEBus ® (Inter Equipment Bus ®) controller for the automotive LAN, and some of the models also include a CAN (Controller Area Network) controller.
