Microchip Technology MEC1701組み込みコントローラ

Microchip Technology MEC1701組み込みコントローラは、ノートPCや工業コンピューティング・プラットフォーム用にカスタマイズされた、高度に構成が可能な混合信号の先端I/Oコントローラです。MEC1701には32ビット機能のArm^® Cortex^®-M4Fマイクロコントローラコアが組み込まれており、コードとデータ用の密結合SRAMが備わっています。セキュアブートローダを使用してシステムの供給SPI Flashデバイスからカスタムファームウェアイメージをダウンロードすることで、システムの設計者はデバイスの動作をカスタマイズできます。

The MEC1701 may be configured to communicate with the system host through one of three host interfaces: Intel Low Pin Count (LPC), eSPI, or I²C. The MEC1701 Controller is designed to operate as either a stand-alone I/O device or as an EC Base Component of a split-architecture Advanced I/O Controller system that uses BC-Link communication protocol to access up to two BC bus companion components. The BC-Link protocol is peer-to-peer providing communication between the MEC1701 Embedded Controller and registers located in a companion device.

The Microchip Technology MEC1701 Embedded Controller is available in WFBGA-144 and WFBFA-169 packages.
