飞思卡尔KV4x微控制器结合电机控制设计工具0

元器件交易网讯 4月17日消息,据外媒报道,飞思卡尔半导体公司的Kinetis V系列微控制器将捆绑电机控制设计工具。

这款KV4x微控制器集成了一枚150MHz ARM Cortex-M4处理器与浮点运算单元结合,通过128位宽的接口执行最高256Kb的闪存,从而减少CPU等待时间。

无传感器电机速度、位置检测方面,两枚12位模拟数字转换器支持高达1.9MS/s的抽样率,可以连接包括计时器、模拟比较器及GPIO在内的微处理器内部外设交叉开关。

以下为原文:

Freescale Semiconductor’s Kinetis V seriesof microcontrollers come with a bundled motor control design tool.

Intended for sensored and sensorless motorcontrol designs, requiring precise speed and position measurement in parallelwith general application task processing, the MCU supports a range of controlalgorithms from entry level BLDC to advanced PMSM and ACIM control loops.

The likely applications range from low-endpool pumps to more advanced robotics.

The KV4x MCUs incorporate a 150MHz ARMCortex-M4 processor with floating-point unit executing from up to 256kbyte offlash memory via a 128-bit wide interface that minimises CPU wait states.

For sensorless motor control speed/positiondetection, two 12-bit ADCs support sample rates of up to 1.9MS/s and can betriggered by any module connected to the MCU’s internal peripheral crossbar,including timers, analogue comparators or GPIO.

The KV3x family, also Cortex-M4 based,targets intermediate PMSM applications with CPU frequencies of 100-120MHz, upto 512/96kbyte of flash/SRAM.

The KV1x family represents the entry-levelof the series with a Cortex-M0+ MCU core.
