4.1.5
LPC Bus
As a part of the replacement to the no longer supported ISA bus, conga-CLX offers the LPC (Low Pin Count) bus through the use of AMD Geode™
CS5536 companion device. There are already 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.
4.1.6
I²C Bus 400kHz
The I²C bus is implemented through the use of ATMEL ATmega88 microcontroller. It provides a Fast Mode (400kHz max.) multi-master I²C Bus
that has maximum I²C bandwidth.
4.1.7
PCI Express™
PCI Express is not supported on the conga-CLX.
4.1.8
ExpressCard™
ExpressCard support is not offered on the conga-CLX.
4.1.9
Graphics Output (VGA/CRT)
The conga-CLX graphics are driven by the graphics processor, which is incorporated into the AMD Geode™ LX800 chip found on the conga-CLX.
This graphic processor offers strong improvements over the original GX core used on Geode™ chipsets in the past.
4.1.10 LCD
The user interface for flat panels is called EPI (Embedded Panel Interface based on VESA EDID™ 1.3) and is implemented for LVDS (National
Semi. DS90C363 transmitter) flat panels. Auto detection and backlight control are also supported.
4.1.11 TV-Out (optional)
TV-Out support is implemented via the Focus FS453 found on the conga-CLX.
