ADI ADuCM320高性能模拟微控制器开发方案
ADI公司的ADuCM320是采用80 MHz ARM Cortex™-M3处理器控制的高性能模拟微控制器,集成了模拟外设和数字外设以及用于代码和数据的闪存,其中的ADC提供14位1MSPS数据取样,可配置成单端或差分,DAC具有八种电压输出,主要用在10G,40G和100G光网络模块,工业控制和自动化系统,智能传感器和精密仪表以及基站系统.本文介绍了ADuCM320主要特性,框图,以及评估板EVAL-ADuCM320EBZ特性,电路图,材料清单和PCB元件布局图.
The ADuCM320 is a fully integrated single-package device that incorporates high performance analog peripherals together with digital peripherals controlled by an 80 MHz ARM Cortex™-M3 processor and integral flash for code and data.
The ADC on the ADuCM320 provides 14-bit, 1 MSPS data acquisition on up to 16 input pins that can be programmed to be single-ended or differential. Additionally, chip temperature and supply voltages can be measured. The ADC input voltage is 0 V to VREF. A sequencer is provided that allows a user selected set of ADC channels to be measured in sequence without software involvement during the sequence. The sequence can optionally auto repeat at a user-selectable rate.
