XJTAG launches the XJLink-PF20 Controller

16 December, 2025 – XJTAG added the XJLink-PF20 controller to the XJLink-PF series. Following the success of the XJLink-PF40, released earlier this year, the XJLink-PF20 brings the same dependability and robustness to a new 4-TAP two-port configuration, offering both functional and JTAG boundary scan testing with the XJTAG testing suite’s long established power and control. This new configuration offers engineers even more choice across electronics development and production.

Designed in close consultation with industry, the XJLink-PF20 prioritises robustness for the unpredictability of prototyping and development, as well as the challenging environments of production. With ±30 V protection on all pins, you can focus on testing without worrying about damaging your equipment.

Enhanced signal integrity is provided by 20 dedicated ground pins, allowing the XJTAG testing suite to run at-speed even in the noisy and imperfect environments that engineers face every day. The fully configurable pin-out of the XJLink-PF20 allows you to assign JTAG TAPs and general purpose I/O in whatever way you need across the two provided connectors. Tolerant and flexible, users can set up their testing faster and spend less time on adapters and cabling.

The XJTAG suite of tools has been helping engineers bring complex software, firmware and hardware products to fruition for decades with its powerful suite of test and programming tools. The XJLink-PF20 fits easily into existing systems and is compatible with all parts of the XJTAG suite. XJLink-PF20 is supported by XJTAG version 4.2 and later.

Key features of the XJLink-PF20 include:

• Robust – protected to ±30 V on all pins in case of unexpected shorts or other faults
• Tolerant – enhanced signal integrity with additional ground signals and series termination to work with varied projects straight out of the box
• Powerful – compatible with any of XJAnalyser, XJRunner, XJInvestigator, XJDeveloper or XJFlash for all of your programming and test needs
• Multi-functional – capable of advanced JTAG boundary scan testing as well as functional test using GPIO pins
• Multi-TAP – offers up to 4 JTAG TAPs configurable across 20 GPIO pins
• Rugged – physically ruggedised for industrial and in-field environments with various mounting options available
• Fast – capable of market-leading JTAG boundary scan speeds of up to 166 MHz
• Flexible – available with hardware and network licensing options
