Microchip Technology MEC1701 임베디드 컨트롤러

Microchip Technology MEC1701 임베디드 컨트롤러는 노트북 및 산업용 컴퓨팅 플랫폼에 적합한 맞춤형 고급 혼합 신호 I/O 컨트롤러로서, 고도로 구성 가능합니다. MEC1701은 32비트 기능이 있고 코드와 데이터를 위해 긴밀하게 결합된 SRAM 포함 ARM^® Cortex^®-M4F 마이크로컨트롤러 코어를 내장하고 있습니다. 안전한 부트로더를 사용하여 시스템의 공유 SPI 플래시 장치에서 사용자 지정 펌웨어 이미지를 다운로드하므로, 시스템 설계자가 장치의 동작을 사용자 정의할 수 있습니다.

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.
