What is eSPI?

eSPI (Enhanced Serial Peripheral Interface) is a low pin count serial communication interface primarily used on PC platforms. It provides a way for the host to communicate with various peripherals such as the BIOS, embedded controllers, and Super I/O devices. It is a successor to LPC (Low Pin Count) bus, offering higher speed and lower voltage operation, leading to improved performance and power efficiency. eSPI commonly replaces LPC in modern chipsets.
