Keyboard and Embedded Controller Products for Notebook PC
The MEC140X/1X is a family of keyboard and embedded controller designs customized for notebooks and tablet plat-forms. The MEC140X/1X family is a highly-configurable, mixed signal, advanced I/O controller architecture. Everydevice in the family incorporates a 32-bit MIPS32 M14K Microcontroller core with a closely-coupled SRAM for code anddata. A secure boot-loader is used to download the custom firmware image from the system’s shared SPI Flash device,thereby allowing system designers to customize the device’s behavior. The MEC140X/1X products may be configured to communicate with the system host through one of three host inter-faces: Intel Low Pin Count (LPC), eSPI, or I2C. Note that this functionality is product dependent. To see which featuresapply to a specific part in the family see Products on page 3. The document defines the features for all devices in thefamily.The MEC140X/1X products are designed to operate as either a stand-alone I/O device or as an EC Base Componentof a split-architecture Advanced I/O Controller system which uses BC-Link communication protocol to access up to twoBC bus companion components. The BC-Link protocol is peer-to-peer providing communication between theMEC140X/1X embedded controller and registers located in a companion device.The MEC140X/1X is directly powered by a minimum of two separate suspend supply planes (VBAT and VTR) andsenses a third runtime power plane (VCC) to provide “instant on’ and system power management functions. In addition,this family of products has the option to connect the VTR_33_18 power pin to either a 3.3V VTR power supply or a 1.8Vpower supply. This option may only be used with the eSPI Host Interface or the I2C Host Interface. In systems using theI2C Host Interface, ten GPIOs are powered by VTR_33_18, thereby allowing them to operate at either 3.3V or 1.8V. Allthe devices are equipped with a Power Management Interface that supports low-power states and are capable of oper-ating in a Connected Standby system.The MEC140X/1X family of devices offer a software development system interface that includes a Trace FIFO Debugport, a host accessible serial debug port with a 16C550A register interface, a Port 80 BIOS Debug Port, and an In-circuitSerial Programming (ICSP) interface.
