Application Information

The TMPE627 is a standard full PCI Express Mini Card,

providing a user programmable Xilinx Artix-7 7A50T

FPGA.

The TMPE627 provides 14 ESD-protected 5 V-tolerant

TTL lines. 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-up voltage that can be set so +3.3 V,

+5 V and GND.

The 16 bit ADC offers 4 input channels that can be

operated in single-ended or differential mode. It offers

software selectable input voltage ranges of 0-5.12 V, 0-

10 V, 0-10.24 V, ±5 V, ±5.12 V, ±10 V and ±10.24 V with a

sampling rate of up to 200 ksps.

The DAC offers 4 channels of 16 bit analog outputs with

software selectable output voltage ranges of 0-5 V, 0-

10 V, 0-10.8 V, ±5 V, ±10 V or ±10.8 V. The output voltage

range can be individually set per channel. The conversion

time is typ. 10 μs and the DAC outputs are capable to

drive a load of 2 kΩ, with a capacitance up to 4000 pF.

Each TMPE627 is factory calibrated. The calibration

information is stored in an on-board serial EEPROM

unique to each TMPE627 module.

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

the Vivado ILA). With the TA308 Programming Kit direct

JTAG access to the FPGA is possible, using the Xilinx

Platform Cable USB.

User applications for the TMPE627 with 7A50T FPGA can

be developed using the design software Vivado Design

Suite HL WebPACK Edition, which can be downloaded

free of charge from www.xilinx.com.

TEWS offers a well-documented basic FPGA Example

Application design. It includes a constraints file with all

necessary pin assignments and basic timing constraints.

The example design covers the main functionalities of the

TMPE627. It implements PCIe to register mapping and

basic I/O. It comes as a Xilinx Vivado Design Suite project

with source code and as a ready-to-download bit stream.

The TMPE627 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.
