electronica visitors get first look at latest XJTAG JTAG controller

This JTAG controller is due for release in 2025. Attendees can see 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 XJLink-PF40 is designed to handle the challenges of complex, high-density circuit boards, making it an ideal tool for PCB engineers from prototype debug to manufacturing test.

With up to eight JTAG TAPs over 40 I/O pins, the XJLink-PF40 enables multiple test access points to one unit under test (UUT), expanding test coverage for the most demanding applications. The controller offers four voltage domains - each connector can run in a different voltage domain.

Key features & benefits of XJLink-PF40 will be:

• Configurable TAP Frequencies – Each TAP can run at a different frequency
• New connector pin-out:
• 4 x 20-way connectors
• Even-numbered pins are GND for improved signal integrity
• Odd-numbered pins are configurable as I/O or TAP pins.
• Electrically Robust – Protected against voltages of ±30 V on any pin
• Physically Robust – Strong aluminium casing
• Flexible Mounting Options
