Analog Devices Inc. ADuCM36x ARM Cortex-M3 MCU

Analog Devices ADuCM36x微控制器 (MCU) 提供一个完全集成的3.9kSPS、24位数据采集系统。这些MCU在单芯片上集成高性能Σ-Δ模数转换器 (ADC)、32位ARM Cortex™-M3处理器。ADuCM36x器件还自带一个片上32kHz振荡器和一个内部16MHz高频振荡器。ADuCM36x集成了偏上外设，例如UART、I²C和双路SPI串行I/O通信控制器。其他外设包含具有6个输出通道的16位PWM、19引脚GPIO端口、2个通用计时器、唤醒计时器以及系统看门狗计时器。设计人员可将微控制器配置为普通工作模式，功耗为290μA/MHz（包括flash/SRAM IDD）。普通工作模式使得所有外设工作时总系统功耗为1mA。ADuCM36x MCU运行功耗低，非常适合在低功耗运行至关重要的电池供电应中运行。

Designers can configure the microcontroller in a normal operating mode that consumes 290μA/MHz (including flash/SRAM IDD). The normal operating mode results in an overall system current consumption of 1mA when all peripherals are active. With its low-power operation, the ADuCM36x MCUs are ideally suited to operate in battery-powered applications where low-power operation is critical.
