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 pr12V 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.
