Fujitsu Semiconductor Releases Three 32-bit Microcontroller Products

Fujitsu Semiconductor Asia Pte Ltd (FSAL) announced three products from the "MB91580 series" which contain driving motor control function for Electrical Vehicles (EV) and Hybrid Vehicles (HV) as part of the high-performance 32-bit FLASH embedded microcontroller (MCU) "FR family". Sample delivery has started since the end of April 2011.

The "MB91580 series" supports the demand for an automotive driving motor control MCU with a dedicated embedded resolver sensor interface to control the three-phase motor used in EV’s and HV’s, where demand is growing rapidly and globally. This is first time that Fujitsu Semiconductor is delivering driving motor control LSI for eco-cars and supporting demand from the market.

The "MB91580 series" contains a suitable CPU core and peripherals for EV/HV motor control. The dedicated interface circuit in the resolver used for the EV/HV driving motor is embedded in order to achieve system cost reduction as well as contribute to improving motor mobility and reduce energy consumption by realizing a high torque responsive control process which is required for the EV/HV driving motor, claims Fujitsu.
