ADI ADSP－CM408电机控制系统参考设计
ADI公司的ADSP-CM40xF系列是基于ARM® Cortex-M4处理核的带浮点单元的混合信号控制处理器,工作频率高达240MHz,集成了高达384KB SRAM,2MB闪存,用于马车控制和光伏(PV)逆变器控制的加速器和外设,以及包括两个16位SAR ADC和12位DAC,主要用在马达控制,仪器仪表,医疗电子和消费类电子.本文介绍了ADSP-CM40xF主要特性, 系列框图, 模拟子系统框图以及电机控制系统参考设计主要特性, ADI M4控制板和 Oscar-Skylight运动控制EVM 框图,电路图,材料清单和PCB设计图.
The ADSP-CM40xF family of mixed-signal control processors is based on the ARM® Cortex-M4TM processor core with floating-point-unit operating at frequencies up to 240 MHz and integrating up to 384KB of SRAM memory, 2MB of flash memory, accelerators and peripherals optimized for motor control and photo-voltaic (PV) inverter control and an analog module consisting of two 16-bit SAR-type ADCs and two 12-bit DACs. TheADSP-CM40xF family operates from a single voltage supply(VDD_EXT/VDD_ANA), generating its own internal voltage supplies using internal voltage regulators and an external passtransistor.
This family of mixed-signal control processors offers low static power consumption and is produced with a low-power and low voltage design methodology, delivering world class processor and ADC performance with lower power consumption.
