New MotorKit from Fujitsu Eases Development of Automotive and Industrial Motor Control Applications
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.
Integrated Starter Kit Based on the Fujitsu MB91F267N Motor Control MCU
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 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.
