4.1.5
LPC Bus
conga-TCA offers the LPC (Low Pin Count) bus through the use of the Intel
®
CG82NM10 (NM10) PCH. There are many devices available for
this Intel
®
defined bus. The LPC bus corresponds approximately to a serialized ISA bus yet with a significantly reduced number of signals. Due
to the software compatibility to the ISA bus, I/O extensions such as additional serial ports can be easily implemented on an application specific
baseboard using this bus. See section
8.2.1
for more information about the LPC Bus.
4.1.6
I²C Bus Fast mode
The I²C bus is implemented through the congatec board controller (STMicroelectronics STM32). It provides a Fast Mode multi-master I²C Bus
that has maximum I²C bandwidth.
4.1.7
PCI Express™
The Intel
®
CG82NM10 (NM10) PCH chipset featured on the conga-TCA offers four PCI Express™ lanes. Through the use of a PCIe switch, the
conga-TCA provides up to five external PCI Express™ lanes if the optional USB 3.0 is not implemented. The Gen1 PCI Express™ interface
offers support for full 2.5 Gb/s bandwidth in each direction per x1 link. The conga-TCA also has a sixth PCI Express™ lane that is utilized by
the onboard Gigabit Ethernet interface and therefore not available externally.
The five external PCI Express™ lanes are available on the A,B connector row. The PCI Express interface is based on the PCI Express
Specification 1.0a (Gen 1 supporting up to 2.5 Gb/s transfer rate).
4.1.8
ExpressCard™
The conga-TCA supports the implementation of ExpressCards, which requires the dedication of one USB port and a x1 PCI Express link for
each ExpressCard used.
4.1.9
Graphics Output (VGA/CRT)
The conga-TCA graphics are incorporated within the processor found on the conga-TCA. The processor contains an integrated graphics
engine, video decode and a display controller that supports DirectX 9.0, OGL 3.0. It also offers two display pipes that supports dual independent
displays.
