The TPCE280 is a standard height, half-length PCI

Express Revision 3.0 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 PCI Express x8 link from the host board to the XMC

module is enhanced by a PCIe Gen3 Redriver, allowing

safe operation of XMC modules on PCIe mainboards.

The voltage level for the XMC’s main power supply,

VPWR, is selectable via order option. The TPCE280-x0R

variants provide 12V VPWR and the TPCE280-x1R order

options provide 5V VPWR.

The TPCE280 supports XMC front panel I/O, and also P14

and P16 rear I/O independently.

XMC P14 Rear-I/O is offered through a 68-pin ERNI SMC,

right angle male, 1.27mm pitch connector. The I/O lines

are routed differential.

XMC P16 Rear-I/O is implemented through two Samtec

Firefly UCC8 and UEC5 connectors providing access to

the P16 I/O lines.

The TPCE280 provides a fan mounted under the XMC slot

that helps cooling the system. This fan does not occupy a

second PCIe slot as most other carrier solutions do.

The PCIe edge card connector provides +12V and +3.3V.

The TPCE280-1xR uses only the +12V of the PCIe edge

card connector to generate all power supply voltages for

the XMC slot (+3.3V, VPWR and +12V).

According to the PCIe specification, a PCIe x8 card is

allowed to use 25W on its +12V supply which allows to

operate most of the available XMC modules on the

TPCE280-1xR. For XMC modules with increased power

requirements, the TPCE280-2xR offer a PCIe Graphics

Power Connector to supply XMCs with up to 75W.

A 14-pin 2mm JTAG header is available for XMC module

debugging purposes. Four JTAG (TRST# not included)

signals are routed directly to the XMC slot.
