JTAG Interface

JTAG access to the Xilinx Artix-7 device is provided through connector JB1.

Connector JB1 (2 x 6 pin header) is compatible with XMOD JTAG adapter TE0790. This adapter can be inserted from top onto the TE0725, if JB1 is fitted with male pin header. Optionally JB1 can be fitted with pin header from bottom, in that case the JTAG cable connector must be on the base board. When using XMOD-JTAG in JB1 then additionally USB UART is usable, and the push-button on XMOD works as configuration reset.

Recommended TE0790 (XMOD) DIP-switch settings :

  • S2-1: ON
  • S2-2: OFF
  • S2-3: OFF
  • S2-4: OFF

TE0790 can be in some cases used to power up TE0725 (other TE0790 DIP settings), however this is not recommended. TE0790-01 can not supply enough power for TE0725 (LED may blink but the module is not operating properly, especially in case of larger and more sophisticated designs).

Power and Power-On Sequence

To power-up a module, power supply with minimum current capability of 1A is recommended.

Power Supply

TE0725 needs one single power supply with nominal of 3.3V.

Power Consumption

A100TNot configuredTBD*

*TBD - To Be Determined.

Actual power consumption depends on the FPGA design and ambient temperature.

Power-On Sequence

There is no specific or special power-on sequence, single power source is needed as VIN, rest of the sequence is automatic.

Physical Dimensions

Please note that two different units are used on the figures below, SI system millimeters (mm) and imperial system thousandths of an inch(mil). This is because of the 100mil pin headers used, see also explanation below. To convert mils to millimeters and vice versa use formula 100mil's = 2,54mm.


All 100 mil pin headers are in 100 mil grid, the M3 mounting holes are in 50 mil grid aligned to the centers of the 100mil headers. The module is symmetrical, turning it 180 degrees will keep all I/O and Power pins in both 50 pin headers in compatible places.

Operating Temperature Ranges

Commercial grade modules

All parts conform to at least commercial temperature range of 0°C to +70°C.

Industrial grade modules

All parts are at least industrial temperature range of -40°C to +85°C.

The module operating temperature range depends on customer design and cooling solution. Please contact us for options.
