Mini PCIe (Full Size)

The conga-IA5 offers an mPCIe slot on connector X9. This connector shares the SoC's PCIe 0 signals with connector X8 (x1 PCIe slot), via a

multiplexer.

When an mPCIe device is attached to the mPCIe slot (connector X9), the SoC automatically detects the type of device that is attached (via pin

43 — the signal detect pin).

See section 5.10.2 "Mini PCIe (Half Size)" for the mini PCIe Pinout Description.

mPCIe Socket - Connector X9

Connector Type

X9: PCIe mini card socket

Note

Pins 21 and 43 of the mPCIe card must be terminated to ground for card present detection and card type recognition respectively.

The PCIe x1 slot on connector X8 will not function if you insert a mini PCIe card into the mPCIe slot (connector X9). To make use of the PCIe

x1 slot, do not insert any mini PCIe device into the mPCIe slot (connector X9).
