The MEC170x is afamily of keyboard and embedded controller designs customized for notebooks andindustrial computing platforms. The family is a highly-configurable,mixed signal, advanced I/O controller architecture. Every device in the familyincorporates a 32-bit ARM Cortex M4F Microcontroller core with aclosely-coupled SRAM for code and data. A secure bootloader is used todownload the custom firmware image from the system’s shared SPI Flash device,thereby allowing system designers to customize the device’s behavior.
The MEC170x products may be configured to communicate with thesystem host through one of three host interfaces: Intel® Low Pin Count (LPC), eSPI, or I2C. These products aredesigned to operate as either a stand-alone I/O device or as an EC BaseComponent of a split-architecture Advanced I/O Controller system whichuses BC-Link communication protocol to access up to two BC bus companioncomponents. The BC-Link protocol is peer-to-peer, providing communicationbetween the MEC170xembedded controller and registers located in a companion device.
