The product has a slightly unique personality, but is interesting.

For the engines used for agricultural machines, construction machines, industrial machines, railway, etc., high-speed and high-accuracy control by microcontrollers is required even under a strict environment of low and high temperature to enhance the fuel consumption and reduce the CO2 emission.
The microcontroller introduced here incorporates the higher CPU performance, larger memory space, wider temperature range, and peripheral functions optimum for the applications, and best suited to the utility engines.

  • High-performance RH850/E1x series and SH7250 series incorporates the floating-point operation unit for the engine control
  • SH72Ax series fully utilizes the performance of the motors and provides the high-efficient and optimum control
  • Automotive microcontroller V850E2/Fx4-L boasts the enriched package products
