ULINK2 USB-JTAG Adapter

 


Features

  • Supports various ARM7, ARM9, Cortex-M, 8051, and C166 devices
  • JTAG speed up to 10MHz
  • Serial Wire Debug (SWD) support for ARM Cortex-M based devices
  • Serial Wire Viewer (SWV) Data Trace for Cortex-M up to 1Mbit/s (UART mode)
  • Real-Time Agent with memory R/W during execution, terminal emulation, and serial debug output
  • Seamless integration with the Keil µVision IDE & Debugger
  • Wide target voltage range: 2.7V - 5.5V
  • USB powered (no power supply required)
  • Plug-and-Play installation using standard Windows USB drivers
  • Target Connectors
    • 10-pin (0.05") - Cortex Debug Connector
    • 20-pin (0.10") - ARM Standard JTAG Connector

ULINK2 may be used for:

  • On-chip Debugging (using on-chip JTAG, SWD, or SWV),
  • Flash Memory Programming (using user-configurable Flash programming algorithms).

Using the ULINK2 adapter together with the Keil µVision IDE/Debugger, you can easily create, download, and test embedded applications on target hardware.

Note - ULINK2 support is available in:

  • MDK 3.04 or higher,
  • C51 8.15 or higher,
  • C166 6.06 or higher.
