ULINKplus: Compact debug adapter with test I/O and power measurement

1 minute read time.

Ultra-low power applications require careful software validation to achieve long battery lifetimes and sensitive hardware needs electrical isolated test connections to prevent from interference voltages. Test automation and scripted testing need ways to interact with the unit under test, for example to stimulate input pins of the target application.

At embedded world, Arm introduces the new Keil ULINKplus debug/trace adapter with innovative features solving all these problems:

  • Integrated power measurement synchronized to event tracing which makes it easy to optimize the overall energy envelope of a system.
  • Isolated JTAG/serial-wire connection to the target hardware is essential for testing applications such as motor control, power converters, or systems with sensitive analog processing.
  • Additional test I/O pins are accessible from the debugger and debug scripts to interact with the target and control automated test stands.

ULINKplus connects to Arm Cortex processors and offers multi-core debugging. It uses the CMSIS-DAP interface which is widely supported by many debuggers.

 

Versatile functions in a compact enclosure: ULINKplus

Power Measurement

The 3-pin power measurement interface is 1 kV isolated. The µVision debugger captures the voltage and current input from the device and displays it in a built-in analyzer:

Test Automation

The test I/O pins can be connected to the target system and allow you to control automated tests. The µVision gives you direct access to these I/O pins using a dialog or virtual debug registers that are accessible via a scripting language.
