Designed specifically to support motor control requirements, Fujitsu Semiconductor America’s series of 32-bit microcontrollers (MCUs) combines performance with a wide range of peripheral functions. The MB91580 series enables optimal, high-speed, efficient three-phase inverter motor control in electric (EV) and hybrid vehicles (HV). Part of the FR family of 32-bit RISC architecture MCUs, the series incorporates embedded flash memory. Applications for the MCUs include EV/HV motor and electric generator control as well as generic, high-performance electric motor control. Highly efficient loop-back control is achieved by using a high-speed, dedicated 12-bit A/D converter and resolver-to-digital converter.
