Analog Devices Inc. ADuCM36x ARM Cortex-M3 MCU

Analog Devices ADuCM36x 마이크로컨트롤러(MCU)는 완전히 통합된, 3.9kSPS 24비트 데이터 획득 시스템을 제공합니다. 이 MCU는 고성능 시그마-델타(Σ-Δ) 아날로그-디지털 컨버터 (ADC), 32비트 ARM Cortex™-M3 프로세서를 통합하고 있습니다. ADuCM36x 장치는 온칩 32kHz 발진기 및 내부 16MHz 고주파 발진기를 포함하고 있습니다. ADuCM36x는 UART, I²C 및 이중 SPI 직렬 I/O 커뮤니케이션 컨트롤러 같은 온칩 주변기기를 통합하고 있습니다. 추가적인 주변기기로 6채널, 19-핀 GPIO 포트, 2개 일반용 타이머, 웨이크업 타이머 및 시스템 감시 타이머를 가진 16비트 PWM이 있습니다. 설계자는 290μA/MHz(플래시/SRAM IDD)를 소비하는 정상작동 모드에서 마이크로컨트롤러를 구성할 수 있습니다. 정상 작동 모드에서는 모든 주변기기가 활성화되면 전반적으로 1mA의 시스템 전류를 소비하게 됩니다. 저전력에서 작동하는 ADuCM36x MCU는 저전력 작동이 중요한 배터리 기반 애플리케이션에서 작동하는데 적합합니다.

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.
