1 Product Description
The TPCE260 is a standard height PCI Express Revision 1.1 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 TPCE260 is a
versatile solution to upgrade well known PMC I/O solutions to the PCI Express signaling standard.
The bridging between the system host board and the PMC slot is handled by the transparent PCIe-to-PCI
Bridge PI7C9X111SL from Pericom.
The PCI bus side of the bridge allows 32-bit PCI accesses with either 33 MHz or 66 MHz. Both 3.3V (TPCE260-
x1R) and 5V (TPCE260-x0R) PCI I/O signaling voltages are supported.
The TPCE260 supports PMC front panel I/O and also PMC P14 Rear I/O 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”).
The PCIe edge card connector provides +12V and +3.3V. All TPCE260-xx variants use the +3.3V solely to
power the PCIe-to-PCI Bridge. The TPCE260-1xR 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 TPCE260-1xR.
For PMC modules with increased power requirements, the TPCE260-2xR offer a 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 TPCE260 is sensitive to static electricity. Packing, unpacking
and all other handling of the TPCE260 has to be done in an ESD/EOS
protected Area.
PCI Bus Signaling Voltage and Keying
Be sure that the TPCE260 PCI bus signal voltage configuration
matches the TPCE260 PMC slots keying pin configuration.
If PMC modules are plugged into a PCI environment where the PCI
signaling voltage does not match, damage to the equipment could
occur, voiding product warranties.
Refer to the chapter “PCI Signaling Voltage” for details.
Power Limits for PMC Modules
The PCIe specification limits the power for PCIe add-in cards. These
limitations have implications for the use of PMC modules.
Refer to the chapter “Power Limits for PMC Modules” for details.
Installation of PMC Modules
Before mounting PMC Modules on the TPCE260, be sure that the
system is powered off.
Also, follow the installation instructions in the “PMC Interface”
chapter.
Installation of TPCE260-2xR
For the TPCE260-2xR variants, it is imperative to always connect a
PCI Express VGA power connector to the TPCE260, even if no PMC
is mounted.

PCI Clock Frequency
The TPCE260 supports 66 MHz PCI clock frequency. The actual PCI clock frequency on the TPCE260 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.
Configuration EEPROM
After PCIe reset, the PI7C9X111SL loads initial configuration register data from an on board configuration I2C
EEPROM. The content is a complete set of configuration parameters based on the default settings with the
subsequent modifications.
For detailed information please refer to the PI7C9X111SL manual and Errata information.

5 PMC Interface
PMC BUSMODE[4:1] Signals
The BUSMODE[4:1]# signals are defined in the IEEE1386 (CMC) specification and allow a host to identify the
used mezzanine card type. The TPCE260 supports PMC cards only.
The TPCE260 indicates the “PMC only” support with the signal levels presented in the table below. The PMC
card should decode these signals and drive out a logic “0” on BUSMODE1#.
Signal Logic Level
BUSMODE4# Pulled LOW
BUSMODE3# Pulled LOW
BUSMODE2# Pulled HIGH
Table 5-1 : TPCE260 PMC BUSMODE[4:1] Signals
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 TPCE260 onboard V_I/O voltage level defines the PCI signaling voltage level for the TPCE260 PCI bus.
A voltage keying pin indicates the voltage level and prevents incompatible PMC modules from being plugged
onto the carrier.

Table 5-2 : TPCE260 PCI Signaling Voltage Factory Defaults
5.2.1 V_I/O Configuration
The V_I/O signaling voltage level is configured by three resistors. To change the voltage level, these resistors
must be soldered to the appropriate soldering terminals. They are grouped and labeled appropriately.

5.2.2 Voltage Keying Configuration
To prevent a PMC module from being plugged into a PMC system with a different PCI signaling voltage, the
PMC specification defines a voltage keying system with keying pins (on the PMC carrier board) and keying
holes (on the PMC module).
PMC modules supporting only 5V PCI signaling voltage provide a single keying hole for the 5V keying pin.
PMC modules supporting only 3.3V PCI signaling voltage provide a single keying hole for the 3.3V keying pin.
Universal PMC modules supporting both 3.3V and 5V PCI signaling voltages provide keying holes for both
voltage keying pins.
In certain system configurations it may be necessary to remove the keying pin from one location and assemble
it at the other keying pin location.

Installation of a PMC Module
The PMC modules are mounted to the TPCE260 prior to installation into the system.
If the PMC has a front panel, first remove the cover from the PMC front panel cut-out of the TPCE260. Install
the PMC at an angle so that the PMC front panel penetrates the PMC front panel cut-out. Then rotate down to
mate with the PMC connectors on the TPCE260. If the PMC has no front panel, simply plug in the PMC, and
leave the cover in the PMC front panel cut-out of the TPCE260.
After the PMC module has been installed, it can be mounted on the TPCE260 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.
Before installing a PMC module, be sure that the power supply for the TPCE260 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.
WARNING!!!
Be sure that the TPCE260 PCI bus signaling voltage (V_I/O) configuration matches the TPCE260
PMC slots keying pin configuration.
Be sure that the used PMC modules match the TPCE260 PCI bus signaling voltage and PMC slot
keying pin configuration.
If PMC modules are plugged into a PCI environment where the PCI signaling voltage does not
match, damage to the equipment could occur, voiding product warranties.
