What is an embedded controller?

An embedded controller Is a high-performance MCU with integrated I/O features. These units can control boot-up procedures, I/O devices, thermal management, power management, and keyboards.

What is the difference between an embedded controller and Super I/O devices?

Embedded Controllers and Super I/Os are two fundamentally different products. An embedded controller has a microcontroller core while a super I/O device does not. Embedded controllers are often used in mobile computing applications while Super I/O Controllers are used in stationary computing applications.

What is eSPI Host Interface?

The eSPI host interface is set to completely replace the LPC interface host interface by 2018. These interfaces define the way embedded controllers, super I/O, and base management controllers communicate with the host processor.

What are the differences between eSPI and LPC host interfaces?

These interfaces have two entirely different protocols. The eSPI host interface also has many advantages over the LPC interface. For example, eSPI interfaces require less pins, have more support for 1.8 V I/Os, work more efficiently with PCI Express and USB 3, and reduce the number of sideband signal communications.
