Enhanced Serial Peripheral Interface (eSPI)
The PCH provides the Enhanced Serial Peripheral Interface (eSPI) to support connection of an EC (typically used in mobile platform) or an SIO (typically used in desktop platform) to the platform. Below are the key features of the interface:
- 1.8 V support only
- Support for Master Attached Flash and Slave Attached Flash.
- Support for up to 50 MHz (configured by soft straps)
- Up to quad mode support
- Support for PECI over eSPI
- Support for Multiple OOB Master (dedicated OOB channel for different OOB masters in the PCH such as PMC and Intel® CSME)
- Transmitting RTC time/date to the target device upon request
- In-band messages for communication between the PCH and slave device to eliminate side-band signals.
- Real time SPI flash sharing, allowing real time operational access by the PCH and slave device.
