ADI公的ADSP-CM40x系列是基于ARM® Cortex-M4内核的混合信号控制处理器,具有浮点运算单元,工作频率高达240MHz,并集成了高达384KB SRAM,2MB闪存,加速器和外设备以及包括两个16位SAR型ADC和两个12位DAC的模拟模块,最适合用在马达控制和光伏(PV)逆变器控制.本文介绍了ADSP-CM40x系列主要特性和框图,内核Cortex-M4框图以及ADSP-CM408F EZ-KIT Lite®评估系统主要特性,框图,电路图和材料清单, PCB元件布局图.
The ADSP-CM40x 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. The ADSP-CM40x family operates from a single voltage supply (VDD_EXT/VDD_ANA), generating its own internal voltage supplies using internal voltage regulators and an external pass transistor.
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.
