2.5.4.2 PC/104-Plus (ISA)
The PCI interface is connected to the ISA part of the PC/104-Plus connector through the
iTE IT8888 PCI-to-ISA chip.
2.5.5 PCIe Bus
The Intel® ICH7M Southbridge chipset has four PCIe lanes. Two of the four PCIe lanes
are interfaced to PCIe GbE controllers. The other two are connected to the two PCIe Mini
card slots.
2.5.5.1 PCIe GbE Ethernet
Two PCIe lanes are connected to two Realtek RTL8111C PCIe GbE controllers shown in
Figure 2-5 . The Realtek RTL8111C PCIe GbE provide 1.0 Gb/s transfer rates in gigabit
networks. Gigabit networks require Cat-5 network cable or above
2.5.5.2 PCIe Mini Card
Two PCIe lanes are connected to the PCIe Mini card slots shown in Figure 2-5 . Both PCIe
Mini card slots contain a PCIe x1 and USB 2.0 interface. PCIe Mini cards can utilize either
of these two interfaces, depending on design requirements.
2.5.6 Real Time Clock
256 bytes of battery backed RAM is provided by the Motorola MC146818 A real time clock
(RTC) integrated into the ICH6. The RTC operates on a 3 V battery and 32.768 KHz
crystal. The RTC keeps track of the time and stores system data even when the system is
turned off.
2.5.7 SATA Controller
The integrated SATA controller on the Intel® ICH7M Southbridge supports two SATA
drives with independent DMA operations. Two SATA controllers are connected to two
SATA connectors on the eNOVA-945GSE. The SATA connectors are shown in
Figure 2-5 .
SATA controller specifications are listed below.
