LPC Bus4.1.5

conga-B915 offers the LPC (Low Pin Count) bus through the use of the Intel

82801FBM (ICH6M). There are already many devices available

for this Intel dened bus. The LPC bus corresponds approximately to a serialized ISA bus yet with a signicantly 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

specic baseboard using this bus. See section 8.2.1 for more information about the LPC Bus.

I²C Bus 400kHz4.1.6

The I²C bus is implemented through the use of ATMEL ATmega168 microcontroller. It provides a Fast Mode (400kHz max.) multi-master I²C

Bus that has maximum I²C bandwidth.

PCI Express™4.1.7

The conga-B915 offers 4x x1 PCI Express links via the Intel

82801FBM (ICH6M), which can be congured to support PCI Express edge cards

or ExpressCards. One of the four x1 PCI Express links is utilized by the onboard Gigabit Ethernet controller therefore there are only 3x x1 PCI

Express links available on the A,B connector row.

ExpressCard™4.1.8

The conga-B915 supports the implementation of ExpressCards, which requires the dedication of one USB port and one PCI Express link for

each ExpressCard used.

Graphics Output (VGA/CRT)4.1.9

The conga-B915 graphics are driven by an Intel

Graphics Media Accelerator 900 engine, which is incorporated into the Intel

82910GMLE/82915GME chipset found on the conga-B915.

LCD4.1.10

The Intel

82910GMLE/82915GME chipset, found on the conga-B915, offers an integrated dual channel LVDS interface that is connected to

Display Pipe B.
