Renesas Electronics Announces Dedicated Motor Control Circuit Technology for Automotive Microcontrollers to Boost the Energy Efficiency of Next-Generation Electric Vehicles

Reduces Operation Time to 1/10 or Less that of Software Implementation on the CPU While Providing Functional Safety

Renesas Electronics Corporation (TSE: 6723), a premier supplier of advanced semiconductor solutions, today announced the development of a circuit technology dedicated for motor control that realizes green vehicles satisfying stricter automotive CO2 emissions requirements.

The newly developed technology is an Intelligent Motor Timer System (IMTS), a dedicated circuit block that can be integrated into automotive microcontrollers (MCUs) for next-generation electric vehicles (EVs) and hybrid electric vehicles (HEVs). It performs field-oriented-control operations (Note 1), which are essential to EV motor control, in a mere 0.8 microseconds (µs), the world’s fastest rate (Note 2), which is less than 1/10 the operation processing time of software implementation on a CPU running at the same operating frequency.This contributes to the realization of next-generation high-speed EV motors with excellent energy efficiency and inverter systems with high-speed switching performance to drive them.
