The Embedded I/O Company

TMPE623 Reconfigurable FPGA with Digital I/O PCIe Mini Card

TMPE623-10R with Heatsink mounted

TMPE623 without Heatsink

Application Information

The TMPE623 is a standard full PCI Express Mini Card,

providing a user programmable Xilinx Artix-7 7A50T

FPGA.

Depending on the order option the TMPE623 offers 26

ESD-protected 5V-tolerant TTL lines or 13 differential I/O

lines using ESD-protected EIA-422 / EIA-485 compatible

line transceivers or Multipoint-LVDS transceivers.

All I/O lines are individually programmable as input or

output. TTL I/O lines can be set to high, low, or tristate.

Each TTL I/O line has a pull-resistor to a common

programmable pull voltage that can be set so +3.3 V, +5 V

and GND. Differential I/O lines are terminated, EIA-422 /

EIA-485 lines with 120

Ω, M-LVDS lines with 100 Ω.

The I/O signals are accessible through a 30 pin Pico-

Clasp latching connector.

The User FPGA is configured by a SPI flash. An in-circuit

debugging option is available via a JTAG header for read

back and real-time debugging of the FPGA design (using

Xilinx “ChipScope”). For direct JTAG access to the FPGA

using

the

Xilinx

Platform

Cable

USB,

the

TA308

Programming Kit is required.

User applications for the TMPE623 with XC7A50T-2

FPGA can be developed using the design software Vivado

WebPACK which can be downloaded free of charge from

www.xilinx.com.

TEWS offers a well-documented basic FPGA Example

Application design. It includes an .xdc file with all

necessary pin assignments and basic timing constraints.

The example design covers the main functionalities of the

TMPE623. It implements local Bus interface to local

Bridge device, register mapping and basic I/O. It comes as

a Xilinx Vivado project with source code and as a ready-

to-download bit stream.

The TMPE623 provides a basic heatsink to facilitate

thermal management. The heatsink can be used to install

additional cooling solutions like passive or active heatsinks

or to provide a thermal connection to an enclosure.
