1 Product Description
The TPCE275 is a standard height PCI Express, Revision 1.1 compatible module that provides one slot for a
single-width XMC module used to build modular, flexible and cost effective I/O solutions for all kinds of
applications like process control, medical systems, telecommunication and traffic control.
The TPCE275 supports XMC front-panel I/O, and also XMC P14 and P16 Rear-I/O.
XMC P14 Rear-I/O is offered through a VME P2 style connector (IEC 60603-2, Type C). The I/O mapping of
P14 complies with VITA-35 (“PMC P4 to VME-P2, Rows A-C mapping”).
XMC P16 Rear-I/O is implemented through two 50 pin, 0.1 inch flat ribbon cable connectors providing
access to all P16 I/O lines. The single-ended signals of P16 are all routed to one flat cable connector, while
the differential signals are routed to the second connector.
The operating temperature range is 0°C to +70°C.

3 Handling and Operating Instructions
3.1 ESD Protection
The TPCE275 is sensitive to static electricity. Packing, unpacking
and all other handling of the TPCE275 has to be done in an ESD/EOS
protected Area.
3.2 Power Limits for XMC Modules
The PCIe specification limits the power for PCIe add-in cards. These
limitations have implications for the use of XMC modules.
Refer to the chapter “Power Limits for XMC Modules” for details.
3.3 Installation of XMC Modules
Before mounting XMC Modules on the TPCE275, be sure that the
system is powered off.
Also, follow the installation instructions in the “XMC Interface”
chapter.
3.4 Installation of TPCE275-2xR
For the TPCE275-2xR variants, it is imperative to always connect a
PCI Express VGA power connector to the TPCE275, even if no PMC
is mounted.
3.5 Installation of TPCE275-x0R
For the TPCE275-x0R variants, VPWR is +12V. This voltage is directly
connected from the PCIe connector. The PCIe specification allows
for tolerances of ±8%, whereas the XMC specification allows only for
±5%.
This has to be taken into consideration before plugging the XMC
module onto the TPCE275-x0R.

Table 4-1 : Current Limits for the XMC Modules
4.2 Stable Power Supply
The power supply for the XMC slot is stable approximately 20ms after the system power supply is stable.
4.3 Installation of an XMC Module
The XMC modules are mounted to the TPCE275 prior to installation into the system.
If the XMC has a front panel, first remove the cover from the XMC front panel cut-out of the TPCE275. Install
the XMC at an angle so that the XMC front panel penetrates the XMC front panel cut-out. Then rotate down
to mate with the XMC connectors on the TPCE275. If the XMC has no front panel, simply plug in the XMC,
and leave the cover in the XMC front panel cut-out of the TPCE275.
After the XMC module has been installed, it can be mounted on the TPCE275 using the mounting screws
that come with the XMC module. There are four screw mounting locations, two at the XMC front panel and
two at the standoffs near the XMC bus connectors.
Before installing an XMC module, be sure that the power supply for the TPCE275 is turned off.
The components are Electrostatic Sensitive Devices (ESD). Use an anti-static mat connected to
a wristband when handling or installing the components.

Notes:
1) JTAG lines are routed to a 10pin header onboard, not to the PCIe edge card connector
2) 3.3V_AUX is connected to the PCIe edge card connector, so it is up to the mainboard to deliver this
power supply. If a mainboard does not provide this power supply, it can be changed to 3.3V on the
TPCE275 with a resistor.
3) MVMRO is set to logic high by default, prohibiting write access. It can be changed via a resistor.
4) WAKE# is connected to the PCIe edge card connector, so it is up to the mainboard to provide for this
signal. If this is not the case, WAKE# may be separated from the mainboard via a resistor.
5) ROOT# is not supported; this pin is not connected on the TPCE275 by default. It can be pulled high
via a resistor.
6) SMCLK and SMDAT are not connected to the PCIe edge card connector by default. Both signals can
be connected via series resistors.

6.2 XMC J14 Rear-I/O (X4 - VG64 Connector)
The TPCE275 routes the XMC I/O lines to the VG64 connector compliant to VITA-35 (“PMC P4 to VME-P2,
Rows A-C mapping”). The actual signal assignment of the XMC P14 connector is XMC specific.
