Fujitsu Kit Eases Development Of Motor Control Apps

EMBEDDED SYSTEMS CONFERENCE, San Jose, CA. - Based on the company's 32-bit MB91F267N motor-control microcontroller (MCU), the MotorKit-91F267-MC starter kit promises to simplify the development of three-phase motor control solutions. It provides a 24V/15A three-phase power stage, with different currents available depending on shunt resistors, connectors for an external power stage, Hall sensors, encoder, LCD, current and voltage measurements via an a/d converter, over-current and over-voltage comparator; and isolated RS-232 and CAN interfaces. The MB91F267N features a 32-bit RISC core with a maximum clock speed of 33 MHz and 128 KB of dual-operation flash memory. Other features include two dedicated 10-bit a/d converters with 11 input channels and a sampling speed of 1.2 µs, CAN interface, a two-channel UART with synchronous and asynchronous modes, eight external interrupts plus NMI, pulse-width counter, three-channel, 16-bit reload timer, five-channel DMA, and a MAC unit providing 16-bit x 16-bit +40-bit in one cycle. Pricing for the kit is $850 each. For more information, call Emi Igarashi at FUJITSU MICROELECTRONICS AMERICA INC., Sunnyvale, CA. (408) 737-5647.
