Mini PCIe
A Mini PCIe slot (PCIe ×1) for full-size cards is available on the MBa57xx. Pin assignment see Table 40.
A Mini PCIe card (50.95 × 30 mm
2
) can be used. An additional SIM card holder is available, see chapter 4.2.11.
The AM57xx internal clock is not PCIe compliant. For this reason, a PCIe compliant clock is generated on the MBa57xx with a
9FGV0241AKILF clock generator. Detailed information can be found in the MBa57xx circuit diagram.

When using mPCIe cards, the distance between the board and the card must be taken into account.
The connector for the card is located 3.7 mm above the board. With a heat sink screw connection
with a maximum protrusion of 2 mm, the space defined in the PCIe specification is available.
The voltages provided for the Mini PCIe card may be loaded with the maximum currents specified in
