New JTAG controller delivers an excellent tool for PCB engineers

XJTAG offers a preview of its latest hardware product, the XJLink-PF40 JTAG controller, due for release in 2025 at electronica 2024.

Attendees can get a first look at the upcoming XJLink-PF40 and see the latest version 4.0 of the XJTAG software suite in action, experiencing how XJTAG is driving the future of PCB prototyping and board testing for the production line.

The controller is designed to handle the challenges of complex, high-density circuit boards, making it an excellent tool for PCB engineers, from prototype debugging to manufacturing tests. With up to eight JTAG TAPs over 40 I/O pins, it enables multiple test access points to one unit under test (UUT), expanding test coverage for the most demanding applications.

Key features and benefits of XJLink-PF40 include up to eight JTAG TAPs connecting to one UUT, which is suitable for complex projects. There are four voltage domains, with each connector running in a different voltage domain. It offers configurable TAP frequencies, where each TAP can run at a different frequency. A new connector pin-out provides 4 x 20-way connectors, and even-numbered pins are GND for improved signal integrity, and odd-numbered pins are configurable as I/O or TAP pins. The controller is electrically robust and protected against voltages of ±30V on any pin. The unit is physically robust and constructed from strong aluminium casing with flexible Mounting Options.

Engineers design the company's tools for engineers. Widely employed in R&D, testing, and manufacturing across all industry sectors, they aid engineers with board bring-up, testing, and debugging. The company also provides accelerated flash programming solutions, driving efficiency across development workflows.
