5.9.3 Mini PCIe (Full Size)
The conga-IA3 offers an mPCIe slot on connector X6. This connector supports both mPCIe and mSATA devices. The PCIe signals are routed
from the SoC's PCIe lane 0 to connector X6 (mPCIe/mSATA slot) via two multiplexers. The first multiplexer switches the PCIe signals between
the x1 PCIe slot (connector X9) and the mPCIe/mSATA slot (connector X6). The second multiplexer switches the SATA signals between SATA
port 1 (connector CN2) and mSATA/mPCIe slot.
When an mPCIe or mSATA device is attached to the mPCIe/mSATA slot (connector X6), the SoC detects the connected device via the signal
detect pin (pin 43), sets the communication mode to PCIe or SATA and automatically switches the PCIe/SATA signals to mPCIe/mSATA slot.
See section 5.9.2 "Mini PCIe (Half Size)" for the mini PCIe Pinout Description.
Connector Type
X6: 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 X9 will not function if you insert a mini PCIe card into the mPCIe slot (connector X6). To make use of the PCIe
x1 slot, do not insert any mini PCIe device into the mPCIe slot (connector X6).
