Description
The V850ES/JG2 is a 32-bit single-chip microcontroller 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.In addition to high real-time response characteristics and 1-clock-pitch basic instructions, the V850ES/JG2 features multiply instructions, saturated operation instructions, bit manipulation instructions, etc., realized by a hardware multiplier, as optimum instructions for digital servo control applications. Moreover, as a real-time control system, the V850ES/JG2 enables an extremely high cost-performance for applications that require low power consumption, such as home audio, printers, and digital home electronics.
