The Ultimate in Arm Debug

High performance debug capability, which is ideal when needing fast downloads, adaptive JTAG clock rates, and parallel streaming trace. The DSTREAM-ST has the performance, adaptability-to-target, and broad Arm architecture support required for faster development.



  • Debug on Arm processors from Armv4 to Armv8 and CoreSight trace
  • USB 3.0 and Gigabit Ethernet for direct or remote host connections
  • JTAG clock of up to 180 MHz for lightning fast software development
  • Instrumentation trace and/or Cortex-M instruction trace streamed directly to host PC
  • Wide range of target connectors
  • Flexible DDR trace clock timing up to 300 MHz (600 Mbits/s per pin)
  • Support for up to 4096 CoreSight devices (including CPUs)
  • Remote target reset
  • Device bring-up and test utilities
  • Flexible architecture to support 3rd party IP and debuggers
