MSP430-JTAG-ISO-MK2 is a faster and improved version of our popular MSP430-JTAG-ISO isolated debugger. Now it's even faster, has a 2GB flash inside, file system, ability to measure the power consumption of the target and provides power profiling of the target.


  • Suitable for most MSP430Fxxx flash microcontrollers
  • Uses TI's standard 2x7 pin JTAG connector
  • Spy-Bi-Wire support for the newest TI MSP430 devices
  • Burns the MSP430 JTAG security fuse
  • Optoisolation 1000VDC, target circuit can be high voltage powered (electricity meters safe debugging)
  • Can supply target with variable voltage and can measure the target power consumption in the 10 uA - 300 000 uA range
  • 2GB internal Flash - can work in stand alone (with external power supply +12VDC), mass storage file system can hold multiply target codes inside
  • Works without computer in-field for firmware upgrade
  • The firmware uses version 2 of the MSP430 Debug stack - it is compatible with a large number of software tools
  • Compatible with TI's Code Composer Studio up to version 6.1.2
  • Compatible with IAR Embedded Workbench for MSP430 up to version 5.20.1 software for programming, real time emulation, debugging, step by step program execution, breakpoints, memory dump etc everything all high priced emulators do
  • Works with free GCC C compiler and Insight MSP430 toolchain and debugger
  • Compatible with software tools that have support for MSP430 Debuck Stack version 2 (MSP430.dll v2).
  • Not compatible with newest versions of IAR Embedded Workbench for MSP430 (6.x.x and after)
  • Not compatible with newest versions of Code Composer Studio (6.1.3 and after)
  • Outer dimensions of the box - 110 x 75 x 25mm ~(4.4 x 3.0 x 1.0") + 20cm (8") cable


  • What should be the polarity of the external power supply jack?
  • The inner pin is plus; and there is a protection diode so you can't go wrong.
  • What is the maximum input voltage for the external power supply jack?
  • There should be a 12VDC regulated voltage with a 500mA current source, if more voltage is applied, this will overheat the internal DC/DC isolation converter. The voltage should not exceed 14VDC in any case as it will damage the unit.
  • How safe is debugging what is the insulation voltage with my USB port?
  • You can connect MSP430-JTAG-ISO-MK2 to high voltage target and use with USB port connection, there is 1000VDC insulation.
  • Can I use MSP430-JTAG-ISO-MK2 with XYZ development IDE/tools?
  • The MSP430.dll which is provided with the MSP430-JTAG-ISO-MK2 is 100% compliant to the Texas Instruments MSP430.dll and will work with *every* development software which supports the original TI MSP430-FET and MSP430-USBFET hardware platforms. We have tested IAR EW for MSP430, Code Composer Studio, Rowley CrossWorks, MSPDEBUG and MSPGCC.
  • What voltage is the target programming when MSP430-JTAG-ISO-MK2 is working in stand alone mode?
  • If your target is not powered externally, the MSP430-JTAG-ISO will power it up with 3.3V, if the target is powered, the MSP430-JTAG-ISO-MK2 will detect and follow the target voltage. Note that your target voltage should meet the Flash programming minimum voltage otherwise you will get an error during programming.
  • Other companies charge money for MSP430 programming software, why is yours free?
  • To write MSP430 programming software using the TI MSP430.dll is a very easy job, there would probably be tons of such programmers available if TI was not keeping the DLL content secret. The programmer software we offer is a beta testing software so it may have some bugs although we've been using it for years at home. Now we've decided to release it for the public as we got a number of questions about whether we know of any such software :). As we are a more hardware-oriented company rather than software-oriented and we've never gotten involved in sales of software, we decided to just release it as a freeware and not to hassle with software copy protections and such.Note that it's not open source but a copyrighted software, although it costs you nothing to obtain or distribute it. We are going to fix all reported bugs in a timely manner but keep in mind that it's not a commercial project and our people have a lot of other stuff to do.
