ADI ADSP－CM40x混合信号控制和处理方案

ADI公司的ADSP-CM40x系列是基于ARM® Cortex-M4TM内核的混合信号控制处理器,浮点运算单元工作频率高达240MHz,集成了高达384KB SRAM,2MB 闪存,加速器和最适合用来控制马达和光伏(PV)逆变器控制的外设以及有两个16位SAR型ADC和两个12位DAC组成的模拟模块,单电源工作,主要用在马达控制,嵌入式工业应用,仪器仪表,医疗和消费类电子.本文介绍了ADSP-CM40x主要特性和框图, 模拟子系统框图以及Cortex-M4内核特性和框图, ADSP-CM408F EZ-KIT Lite®评估板主要特性和框图,电路图和材料清单.

The ADSP-CM40x family of mixed-signal control processors is based on the ARM® Cortex-M4TM processor core with floatingpoint 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.
