Fujitsu introduces new 32-bit MCUs used in electric, hybrid vehicles

Can be used to develop optimised, real-time controllability for EV and HV motors

By CBR Staff Writer

Fujitsu Semiconductor America (FSA) has introduced the MB91580, a series of new 32-bit microcontrollers (MCUs).

FSA claims the new MCUs combine performance with peripheral functions to enable optimal, high-speed and efficient 3-phase inverter motor control in electric (EV) and hybrid vehicles (HV).

The new MB91580 series is part of the FR family of 32-bit RISC architecture microcontrollers, which incorporate embedded Flash memory and feature optimised, high-performance peripherals for EV and HV 3-phase inverter motor control.

Applications include EV/HV motor and electric generator control, as well as generic, high-performance, electric motor control.

The MCUs allow the applications to deliver optimised, real-time controllability for EV and HV motors with fast and efficient loopback operation, and torque control, said FSA.

The company also added that the integration and performance enables system designers to reduce overall motor and motor-control unit costs significantly.

The three members in the series are the MB91F585 (with 576 KB Flash and 48 KB RAM); the MB91F586 (with 832 KB Flash and 64 KB RAM); and the MB91F587 (with 1088 KB Flash and 96 KB RAM).

Fujitsu Semiconductor America senior manager for marketing Akio Nezu said the MB91580 series is an ideal design choice for electric and hybrid vehicles because it is designed specifically to support motor control requirements.

Nezu added, "These microcontrollers use a dedicated embedded resolver sensor interface to control the three-phase inverter, resulting in optimal motor controllability. This enables the system designer to achieve higher performance while lowering the system cost."
