ADI ADuCM302x系列微控制器系统评估方案

ADI公司的ADuCM302x系列是超低功耗集成式混合信号微控制器系统,基于ARM® Cortex®-M3处理器,由数字外设,嵌入式SRAM和闪存,一个提供时钟,复位和电源管理功能的模拟子系统以及ADC子系统组成.工作电压1.74 V-3.6 V,主要用在物联网(IoT),智能城市,智能农业,智能机器,智能仪表和智能建筑,可穿戴,健身和医疗等.本文介绍了ADuCM302x系列主要特性,功能框图,以及评估板ADuCM3029 EZ-KIT主要特性,框图,电路图和材料清单.

The ADuCM3027/ADuCM3029 microcontroller units (MCUs)are ultra low power microcontroller systems with integratedpower management for processing, control, and connectivity.

The MCU system is based on the ARM Cortex-M3 processor, acollection of digital peripherals, embedded SRAM and flashmemory, and an analog subsystem which provides clocking,reset, and power management capability in addition to ananalog-to-digital converter (ADC) subsystem.
