ADI ADSP－CM403F混合信号控制处理器开发方案
ADI公司的ADSP-CM403F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,适合用在马达控制,嵌入式工业,仪表,医疗和消费类电子.本文介绍了ADSP－CM40x系列主要特性,框图,模拟子系统框图和ARM Cortex-M4内核框图,以及ADSP-CM403F评估板主要特性,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 lowvoltage design methodology, delivering world class processor and ADC performance with lower power consumption.
