Communication Bus
The conga-IA5 supports both SMBus and I
2
C compliant devices.
5.3.1
SMBus
The SMBus signals are available in different locations on the conga-IA5, including the feature connector (X35) described in section 6.11 of this
document.
5.3.2
I²C Bus
The congatec Board controller provides I²C signals. These signals are available in different locations on the conga-IA5, including the feature
connector (X35) described in section 6.11 of this document.
5.3.3
SPI Bus
The SPI signals are connected to the onboard SPI flash and also to the feature connector (X35). The SPI signals on the feature connector
provides the ability to boot the conga-IA5 from external flash. This however requires a customized adapter for triggering the BIOS_DISABLE#
signal (pin 46) of the feature connector.
Note
The congatec customized adapter for the feature connector is for internal use only.
