This page is a resource for JTAG connectors.  These connectors are commonly used to interface Boundary SCAN tools or JTAG Emulators to a system under test.

A common JTAG interface will have 4 or 5 standard signals (TDI, TDO, TMS, TCK, TRST) and some number of optional pins depending on the device.

There is no physical standard for a JTAG Boundary Scan connector, but there are many commonly used connectors and pin outs.

By following the links below you should be able to find  information on JTAG connector:

  • Pin-outs
  • Connector vendors
  • Tool Pin outs – for tools such as: JTAG Cables, Boundary Scan Testers, JTAG Emulators… etc
  • JTAG device Pinouts

This information can be used to help you create custom connectors to connect your JTAG hardware to our XJLink controller.

Each week we will add new connector pin descriptions. Please let us know if you would like us to add a specific product or device.
