Enhanced Serial Peripheral Interface (eSPI) is developed by Intel as a successor to its Low Pin Count (LPC) bus. So it can carry out not only legacy SPI data but also Embedded Controller (EC), Baseboard Management Controller (BMC) and Super-I/O. This standard allows designers to use 1-bit, 2-bit, or 4-bit communications at speeds from 20 to 66 MHz to further allow designers to trade off performance and cost.

Extend your oscilloscope’s capability with Keysight’s eSPI triggering and decode application. It makes it easy to debug and test designs that include eSPI protocols using your Infiniium oscilloscope.
