How to connect MSP-TS430RGZ48C with RF430CL330HTB?

Other Parts Discussed in Thread: MSP430FR5969, MSP430FR5739, RF430CL330H, MSP-TS430RGZ48C

Hello all,

I am very new to MSP430FR5969 development and I have just purchased a MSP-TS430RGZ48C, which comes with a MSP430FR5969. I would like to access RF430CL330H NFC by connecting RF430CL330HTB to the MSP-TS430RGZ48C. Is there any guideline that I can follow to do so? I would really appreciate the help. Thanks.


  • Hello Bowen,

    Since the RF430CL330H NFC communicates through I2C/SBW, you are going to be using the eUSCI peripheral on the FR5969 for serial communication.  I recommend you start by looking at the code example included in the RF430CL330HTB webpage.  This code is intended for a MSP430FR5739, but with some small alterations it can be used to work on the FR5969.  The main.c file shows a connection diagram as well as a code description to help get you started.  What's really nice is that the UCB0SCL and UCB0SDA pins are the same on both the FR5739 and the FR5969 and the /RST and INTO pins are simply GPIOs, therefore you don't even have to change any pin assignments.

    Good luck,


  • Hello Ryan,

    I am having some trouble to assemble the RF430CL330H with the MSP-TS430RGZ48C. Particularly, I do not know which pins I should connect for power and data. Is there some diagram that clearly illustrates how I can assemble the boards together? Many thanks for your help.



  • Bowen,

    Please refer to the main.c file of the RF430CL330H example code to find how to connect the two boards together. Also shown here:

    RF430 refers to the RF430CL330HTB and the MSP430FR5739 can be replaced with your MSP430FR5969 pin for pin.  S1, S2, and LED5-7 can be ignored.  Supply both boards with a 3.3 V power supply.  On the RF430CL330H, connect Vcc to 3.3V and Vss to GND.  On the MSP-TS430RGZ48C, make sure J1 is set to ext. (if using an external power supply) and connect your 3.3V supply to the Vcc and GND on this board as well.  If using JTAG to power the board, ensure that the JTAG supply level is set for 3.3V and set J1 to int.  Check the individual pins to make sure that AVcc/DVcc are being supplied with 3.3V.

  • The schematic for the MSP-TS430RGZ48C is contained in the MSP430 Hardware Tools User's Guide (

    That plus the datasheet for the RF430CL330H should give you the information on the connections you need to make.

    Don't forget extra items you need, such as I2C pullup resistors, supply decoupling capacitors, and your passive antenna elements.
