Platform Controller Hub EG20T
The Intel
®
PCH EG20T was developed for IO extension of the processor. The features
of the Intel
®
PCH EG20T provide the functionality necessary for storage and
connectivity as well as functionality normally associated with handheld devices such as
SDIO/MMC and USB device.The Intel
®
PCH EG20T has several functions as follows:
• Interface to processor of PCI Express* x1 lane (Gen1)
• One GMAC interface for Gigabit Ethernet
• Two SATA ports, Gen2
• Six USB 2.0HS Host compatible ports
• One USB 2.0HS Client compatible port
• Two SDIO/MMC interfaces
• Four UART interfaces
• One CAN interface
• One Serial Peripheral Interface (SPI)
• One I
