1 Product Description

The TPCE261 is a standard height PCI Express Revision 2.0 compatible module that provides one slot for a

single-width PMC 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 TPCE261 is a

versatile solution to upgrade well known PMC I/O solutions to the PCI Express signaling standard.

On the PCI Express side, an x1 link with 2.5GT/s speed to the host board is provided.

The bridging between the system host board and the PMC slot is handled by the transparent PCIe-to-PCI

Bridge XIO2001 from Texas Instruments.

On the PMC side, PCI signaling voltages of 3.3V (TPCE261-x1R) and 5V (TPCE261-x0R) are supported. 32-

bit PCI accesses are possible with 33MHz or 66MHz.

The TPCE261 supports PMC front-panel I/O and also PMC P14 Rear-I/O through a 68-pin ERNI SMC

1.27mm flat cable connector.

The PCIe edge card connector provides +12V and +3.3V. All TPCE261-xx variants do not use the +3.3V at

all. The TPCE261-1xR uses the +12V of the PCIe edge card connector to generate all four power supply

voltages for the PMC slot (+3.3V, +5V, +12V and -12V). According to the PCIe specification, a PCIe x1 card

is limited to 6W on the +12V which allows to operate most of the available 32-bit 33/66 MHz PMC modules

on the TPCE261-1xR.

For PMC modules with increased power requirements, the TPCE261-2xR offer an additional PCIe Graphics

Power Connector to supply the +12V for generating all the power supply voltages for the PMC slot providing

a power of up to 25W.

3 Handling and Operating Instructions

ESD Protection

The TPCE261 is sensitive to static electricity. Packing, unpacking

and all other handling of the TPCE261 has to be done in an ESD/EOS

protected Area.

Installation of TPCE261-2xR

For the TPCE261-2xR variants, it is imperative to always connect a

PCI Express VGA power connector to the TPCE261, even if no PMC

is mounted.

TPCE261 User Manual Issue 1.0.2 Page 9 of 20

4 PMC Interface

Installation of a PMC Module

The PMC modules are mounted to the TPCE261 prior to installation into the system.

Before installing a PMC module, be sure that the power supply for the TPCE261 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.

After the PMC module has been installed, it can be secured on the TPCE261 using the mounting screws that

come with the PMC module. There are four screw mounting locations, two at the PMC front panel and two at

the standoffs near the PMC bus connectors.

PCI Signaling Voltage

PMC modules are specified either for 3.3V only, 5V only or universal (3.3V or 5V) PCI signaling voltage

operation.

The TPCE261 onboard V_I/O voltage level defines the PCI signaling voltage level for the TPCE261 PCI bus.

A voltage keying pin indicates (and also selects) the voltage level and prevents incompatible PMC modules

from being plugged onto the carrier.

PCI Bus Device Number Mapping

The PCI bus device number of the PMC slot is defined by configuration type translation of the PCI-Express

to PCI Bridge.

By default, the PMC slot is mapped to the bus device number 0x0.

PCI Clock Frequency

The TPCE261 supports 66 MHz PCI clock frequency. The actual PCI clock frequency on the TPCE261 is

configured by the plugged PMC module. If the plugged PMC module supports 66 MHz operation, the PCI

bus will operate with 66 MHz; otherwise it will operate with 33 MHz.
