Analog Devices Inc. ADuCM36x ARM Cortex-M3 MCU
Analog Devices ADuCM36xマイクロコントローラ(MCU)は、完全統合3.9kSPS、24ビットデータ収集システムを実現しています。これらのMCUには、高性能シグマデルタ(Σ-Δ)アナログデジタルコンバータ(ADC)、32ビットARM Cortex™-M3プロセッサが組み込まれています。ADuCM36xデバイスには、オンチップ32kHz発振器および内部16MHz高周波数発振器も含まれています。ADuCM36xには、UART、I²C、デュアルSPIシリアルI/O通信コントローラといったオンチップペリフェラルが組み込まれています。その他のペリフェラルには、6個の出力チャンネルを備えた16ビットPWM、19ピンGPIOポート、2個の汎用タイマ、ウェイクアップタイマ、およびシステム監視タイマがあります。290μA/MHz(Flash/SRAM IDDを含む)を消費する通常の動作モードにおいて、マイクロコントローラを構成できます。通常の動作モードでは、すべての周辺機器が有効な場合、全体的なシステム電流消費は1mAです。低消費電力動作を備えたADuCM36x MCUは、低消費電力動作が重要になるバッテリ駆動アプリケーションでの使用に最適です。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.
