SM Bus

The SM Bus signals are available on the feature connector X53 described in section 5.22 “Feature Connector”. The SM Bus on the module is 
powered by the standby power rail. 

5.12.1 

I

2

C Digital I/O

The conga-MEVAL provides two GPIO expansion headers (X50 and X51) for I

2

C applications. The GPIO signals are provided with 3.3 V power 

supply via a 16-bit I2C I/O expander (PCA9555). 

The I2C device address for the expansion headers is 0x4E (least significant bit is set to a write operation). The table below describes the X50/
X51 pinout. For more information, contact the congatec technical support team.
