Fujitsu Microelectronics Europe (FME) has unveiled the MotorKit-91F267-MC starter kit designed to simplify the development of 3-phase motor control solutions using the company's MB91F267N 32bit motor control MCU.

Rich feature mix
The MB91F267N MCU is optimized for industrial and automotive 3-phase motor control and offers a rich feature mix designed to target applications in these markets. 3-phase motors are increasingly being used in industrial, automotive and home appliance applications where high reliability, low acoustic noise, variable speed capability and high efficiency are requirements.

Featuring Fujitsu's 32bit RISC (FR) core with a maximum internal clock speed of 33MHz (PLLx8), the MB91F267N has 128kB dual-operation flash memory that enables write, read and erase operations to be performed separately in each bank for easy data storage configuration. A flexible multifunction timer for motor control provides: 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.

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

Key features include an integrated 24V/15A (configuration dependent) 3-phase power stage; connectors for an external power stage; voltage and current measurement; an LCD connector; Hall/encoder connector (to ICU); isolated RS232 and CAN interfaces; and overcurrent and overvoltage detection.
