MEC1703中文资料Embedded Controller数据手册Microchip规格书

描述 Description

MEC1703 adds 2KB EEPROM.The MEC170x is a family of keyboard and embedded controller designs customized for notebooks and industrial computing platforms.  The family is a highly-configurable, mixed signal, advanced I/O controller architecture. Every device in the family incorporates a 32-bit ARM Cortex M4F Microcontroller core with a closely-coupled SRAM for code and data. A secure bootloader is used to download the custom firmware image from the system’s shared SPI Flash device, thereby allowing system designers tocustomize the device’s behavior.MEC170x products may be configured to communicate with the system host through one of three host interfaces: Intel Low Pin Count (LPC), eSPI, or I2C. This family of products are 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 which 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 MEC170x embedded controller and registers located in a companion device.Family parts MEC1703K-F2-SZ MEC1703K-P2-X/XY MEC1703K-P2-XY MEC1703Q-C2-XY MEC1703Q-F2-SZNOTE: While the MEC170x family of embedded controllers is still supported, the enhanced features offered by the latest MEC152x and MEC172x families are highly recommended for new designs.
