Platform to develop
three-phase motor control apps
A development platform for automotive and industrial motor-control applications built around a 32bit microcontroller is designed to simplify development of three-phase motor-control systems
Fujitsu Microelectronics has introduced a new development platform for automotive and industrial motor-control applications built around its MB91F267N 32bit microcontroller. The MotorKit-91F267-MC starter kit has been designed to simplify development of three-phase motor-control systems. It provides an integrated 24V/15A three-phase power stage, with different currents available depending on shunt resistors.

Single embedded FRAM chip provides display data memory for four HDMI connector ports, which previously required separate memory for each port
The kit also includes connectors for external power stage, Hall sensors, encoder, and LCD; current and voltage measurements with ADC, over-current and overvoltage 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', says Akio Nezu, Senior Manager, Embedded Solutions Business Group, Fujitsu Microelectronics America.
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 includes Fujitsu's 32bit RISC core with a maximum internal clock speed of 33MHz (PLLx8), along with 128Kbyte 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 multifunction timer for motor control provides the following: 6-channel compare, 4-channel input capture; 4-channel (16bit) or 8-channel (8bit) PPG; 3-channel 16bit free-run timer; and a waveform generator with dead-time generation and fault input.
Other features include two dedicated 10bit ADC units with 11 input channels; a one-channel CAN interface; a two-channel UART with synchronous and asynchronous modes; eight external interrupts plus NMI; a pulse-width counter; three-channel, 16bit reload timer; a five-channel DMA; and a MAC unit providing 16 x 16bit +40bit in one cycle.
Pricing for the kit is US $850 each.
