AcroPack Series XMCAP2022
XMC Carrier Board

and only supplied when The Present* Pin (45) of the AcroPack module is seen to
be grounded.
4.
All +3.3Vaux power pins are changed to 3.3V power.
5.
The SM bus signals SMB_CLK and SMB_DATA are used to communicate with a
CPLD on the carrier that reports slot ID. These signals will be under the control of
the AcroPack module.
XMC/PCIe Bus Connections
Table4 indicates the pin assignments for the PCIe bus signals at the XMC VITA
42.3 connector P15.
Refer to the PCI Express bus specification for additional information on the
PCI Express bus signals.

Notes:
1.
Asterisk (*) is used to indicate an active-low signal.
2.
+3.3Vaux power is not used by the carrier. Contact Acromag to 3.3Vaux
power to AcroPack modules and/or ID EEPROM. The carrier pr3.3V
power to the modules.
3.
+12V_AUX and -12V_AUX are not used by the carrier. +12V and -12V are created
from +3.3V to support XMC carriers that do not supply these voltages.
JTAG Programming/Debug Connector
JTAG programming/debug is supported through the JTAG signals of the XMC
P15 connector. An alternate header is supplied if JTAG is not available from
the XMC carrier (See reference designator J3 located on bottom side of
