New MotorKit from Fujitsu Eases Development of Automotive and Industrial Motor Control Applications

Integrated Starter Kit Based on the Fujitsu MB91F267N Motor Control MCU

Fujitsu Semiconductor America Inc.

Sunnyvale, CA, April 02, 2007

Fujitsu Microelectronics America, Inc. (FMA) today introduced a new development platform for automotive and industrial motor control applications built around the Fujitsu MB91F267N 32-bit microcontroller.

The MotorKit-91F267-MC starter kit has been designed to simplify development of three-phase motor control solutions. It provides an integrated 24V/15A three-phase power stage, with different currents available depending on shunt resistors. The kit also includes connectors for external power stage, Hall sensors, encoder, and LCD; current and voltage measurements with ADC, over-current and over-voltage comparator; and isolated RS232 and CAN interfaces.

“The new MotorKit is an ideal development platform for many advanced motor control applications including brushless DC motors, permanent magnet synchronous motors with sinusoidal commutation, and vector control of PMSM/ACIM,” said Akio Nezu, senior manager, Embedded Solutions Business Group, Fujitsu Microelectronics America.

Built around Fujitsu’s High-Performance Motor Control MCU

The kit is based on the MB91F267N, a highly integrated microcontroller that provides the low acoustic noise, variable speeds, high efficiency, and maximum reliability required in new generations of three-phase motor control designs for automotive, industrial and home appliance applications.

The MB91F267N features Fujitsu’s 32-bit RISC (FR) core with a maximum internal clock speed of 33MHz (PLLx8), along with 128kB dual-operation flash memory. The flash memory enables users to perform write, read and erase operations separately in each bank for easy data storage configuration. A flexible multi-function timer for motor control provides the following: 6-channel compare, 4-channel input capture; 4-channel (16-bit) or 8-channel (8-bit) PPG; 3-channel 16-bit free-run timer; and a waveform generator with dead-time generation and fault input.

Other features include two dedicated 10-bit ADC units with 11 input channels (4 + 7-channels) and a sampling speed of 1.2μs; a 1-channel CAN interface; a 2-channel UART with synchronous and asynchronous modes; eight external interrupts plus NMI; a pulse-width counter; 3-channel, 16-bit reload timer; a 5-channel DMA; and a MAC unit providing 16-bit x 16-bit +40-bit in one cycle.

Pricing for the kit is $850 each.
