Utility Interfaces

Besides the high speed mezzanine interface connectors P-HSE and P-PCIE, the SC3-LARGO is provided

with the utility interface expansion connector socket P-EXP. This connector comprises several

interfaces, which may be useful for system expansion on mezzanine cards, as an option:

< HD Audio

< LPC (Low Pin Count)

< SMBus

< 2 x USB

The SMBus is controlled by the QM87 platform controller hub. The SMBus signal lines on the P-EXP

utility expansion connector can be switched on/off under software control (PCH GPIO) in order to

isolate external components in case of an I

C address conflict.

The HD Audio port requires an additional audio codec, as provided e.g. on the PCS-BALLET side card.

The LPC bus presents an easy way to add legacy interfaces to the system. EKF offers a variety of

mezzanine expansion boards (side cards), to be attached on top of the SC3-LARGO, featuring all

classic Super-I/O functionality, for example the PCS-BALLET. Access to the connectors PS/2 (mouse,

keyboard), COM, USB and audio in/out is given directly from the front panel.
