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 protocol - it compatible with a large number of software tools.
  • Not compatible with software tools that use only the version 3 of the MSP430 protocol.
  • 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.
