Olimex Ltd is a leading provider for development tools and programmers for embedded market. The company has over 20 years’ experience in designing, prototyping and manufacturing printed circuit boards, sub-assemblies, and complete electronic products. 



Product: ARM-JTAG-EW


ARM-JTAG-EW is fast and reliable JTAG programmer / debugger designed to work with EW-ARM, the goal was not to release another fast USB JTAG compatible with Embedded Workbench just yet, but to make a low-cost JTAG with features available only in the expensive Logic analyzers. For this purpose ARM-JTAG-EW offers the user not only software breakpoints, but also hardware breakpoints - the user can stop the code by external triggers which may be the target power consumption, rising/falling edge external signals, analogue signal window value. ARM-JTAG-EW emulates on a low level the IAR Systems' J-LINK API so that it works like a normal J-LINK debugger, yet it also adds some unique features which are available only in the very high end and expensive debugger tools on the market.






  • Debug all ARM microcontrollers supported by EW-ARM
  • Fast speed USB 2.0 JTAG dongle interface, can be used with all ARM7 and CortexM0 and CortexM3devices for programming and debugging, ARM9 and MIPS support are planned to be add in future.
  • Can power on/off target with +5VDC on ARM connector PIN#19
  • Monitors the power consumption, you can watch in C-SPY
  • You can set breakpoints at power consumption value
  • You can set external trigger breakpoints i.e. you can stop your code on rising / falling edge of external hardware signal
  • You can set external trigger breakpoint on external analogue value signal i.e. stop our code when the external signal is between 0.85 and 1.25V
  • Uses ARM's standard 2x10 pin JTAG connector
  • Supports ARM targets working in voltage range 2.0– 5.0 V DC
  • Software supported by EW-ARM
  • Available support for OpenOCD
  • Dimensions 50x40 mm (2x1.6") + 20 cm (8") JTAG cable
