　　元器件交易網(wǎng)訊 4月17日消息，據(jù)外媒報(bào)道，飛思卡爾半導(dǎo)體公司的Kinetis V系列微控制器將捆綁電機(jī)控制設(shè)計(jì)工具。

　　這款KV4x微控制器集成了一枚150MHz ARM Cortex-M4處理器與浮點(diǎn)運(yùn)算單元結(jié)合，通過128位寬的接口執(zhí)行最高256Kb的閃存，從而減少CPU等待時(shí)間。

　　無傳感器電機(jī)速度、位置檢測(cè)方面，兩枚12位模擬數(shù)字轉(zhuǎn)換器支持高達(dá)1.9MS/s的抽樣率，可以連接包括計(jì)時(shí)器、模擬比較器及GPIO在內(nèi)的微處理器內(nèi)部外設(shè)交叉開關(guān)。

　　該微處理器從低端池泵到先進(jìn)的機(jī)器人技術(shù)都可使用。（元器件交易網(wǎng)毛毛  譯）

　　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.
