The K24 SOM uses one 240-pin connectors and one 40-pin connector to provide electrical connectivity between the SOM and the carrier card. These two connectors are referred to as SOM240_1 and SOM40. The SOM240_1 connector is backward compatible with SOM240_1 connector on the K26 SOM.
The SOM240_1 connector uses the Samtec 0.635 mm AcceleRate HD high-density 4-row, 60 position connector set. The part number for the socket (ADF6–60–03.5–L–4–2–A) is used on the bottom side of the SOM. The part number for the terminal (ADM6–60–01.5–L–4–2–A) is for use on the carrier card.
The SOM40 connector uses the Samtec 0.635 mm AcceleRate (R) HD high-density 4-row, 10 position connector set. The part number for the socket (ADF6–10–03.5–L–4–2–A) is used on the bottom side of the SOM. The part number for the terminal (ADM6–10–01.5–L–4–2–A) is for use on the carrier card.
The SOM240_1 and SOM40 connectors provide support for following interfaces.
- Control and status signals
- Multiplexed I/O (MIO) bank
- PS-GTR high-speed serial transceiver signals
- High-performance I/O (HPIO) bank signals
- High-density I/O (HDIO) bank signals
- Power system
