MSP-EXP430FR5739 FRAM Experimenter Board
1 Getting Started With the MSP-EXP430FR5739 FRAM Experimenter Board
1.1 Introduction
The MSP-EXP430FR5739 Experimenter Board introduces TI's first embedded ferro-electric random
access memory (FRAM) based MCU, the MSP430FR5739. The experimenter board is an ideal platform
for evaluating the latest in embedded memory technology while allowing the user to easily develop,
debug, and implement prototypes in an efficient manner.
The MSP430FR5739 device is supported by both IAR Embedded Workbench and Code Compose Studio.
It is recommended to download the latest version of the IDE from www.msp430.com.
The Quick Start Guide (SLAU341) is recommended for users who cannot wait to get started developing
with the MSP430FR5739. For all others, this MSP-EXP430FR5739 FRAM Experimenter Board User's
Guide provides detailed information on the hardware, the user experience firmware, and the
MSP430FR5739 device.
The MSP-EXP430FR5739 Experimenter Board is available for purchase from the TI eStore at
https://estore.ti.com/MSP-EXP430FR5739-MSP-EXP430FR5739-Experimenter-Board-P2430C42.aspx.

1.2 Kit Contents
The MSP-EXP430FR5739 FRAM Experimenter Board kit includes the following:
• The MSP-EXP430FR5739 board
• Mini USB-B cable, 0.5 m
• 12-pin PCB connectors (two male and two female)
• 32.768-kHz clock crystal from Microcrystal (www.microcrystal.com)
The 32.768-kHz crystal can be used as the low-frequency XT oscillator. It is not required for the User
Experience code and can be populated as needed.
• Quick start guide
See Section 2.1 for details on the associated software and source code.
1.3 MSP-EXP430FR5739 Board Overview
The experimenter board (see Figure 1) comes equipped with the following features:
• USB debugging and programming interface that uses a driverless installation and provides an
application UART to communicate back to the PC
• On-board ADXL335 accelerometer
• NTC thermistor for temperature sensing
• Two user input switches and a reset switch
• Eight LEDs for output display
• Connectivity to the MSP-EXP430F5438 Experimenter Board
• Connectivity to CCxxx radio daughter cards
• Easily accessible device pins for debugging purposes or as socket for adding customized extension
• Separate power jumpers to measure power to the MSP430 and the RF daughter card.

1.4 Connecting the Hardware
Connect the MSP-EXP430FR5739 to the PC using the enclosed USB cable. If the PC has an MSP430
Integrated Development Environment (IDE) such as Code Composer Studio™ or IAR Embedded
Workbench™ already installed, the driver files are automatically located and installed.
If there are no IDEs installed in the PC, unzip the folder associated with this user's guide (see Section 2.1)
and point the installation to the [Install Path]\MSP-EXP430FR5739\Drivers folder.
After the drivers are installed, go to My Computer → Properties → Hardware → Device Manager to verify
that the board is enumerated under Ports COM & LPT as MSP430 Application UART.
1.5 Starting the PC GUI
The Graphical User Interface (GUI) for the PC is located in the associated zip file (see Section 2.1) under
[Install Path]\MSP-EXP430FR5739\Graphical User Interface.
Double click on FRAM_GUI.exe to load the PC application. More information on how to use this
application is provided in Section 2.

2.1 Associated Zip Folder Contents
The zip file that contains the software and source code for the MSP-EXP430FR5739 can be downloaded
from www.ti.com/lit/zip/slac492. The contents of the zip include:
• User Experience source code and project files
• Drivers that support the board installation
• PC GUI
The design files for the experimenter board are can be downloaded from www.ti.com/lit/zip/slac502.
2.2 The User Experience Demo
The User Experience demo is pre-loaded in the MSP-EXP430FR5739 board.
The user input to the demo is given using the switches S1 and S2. These switched allow the user to
select the mode of operation and other options.
The output from the demo is displayed using the LEDs (LED1 to LED8) and is also sent via the
back-channel UART that transmits information to the PC.
There are four modes of operation for the User Experience demo:
1. High-speed FRAM writes
2. Emulating the speed of flash writes
3. Sampling accelerometer data and writing to FRAM
4. Sampling thermistor data and writing to FRAM

2.2.1 Entering and Exiting the Demo Modes
Follow these steps to enter and exit the demo modes:
1. Press switch S1 for mode selection. After you press S1, LED8 through LED5 light up to show the
corresponding mode.
2. Press switch S2 to enter the mode.
3. Press switch S2 when inside a mode to turn off the display (LED and UART output). This is useful
when measuring power.
4. Press S1 to exit a mode and return to mode selection.
NOTE: Pressing S2 without selecting a mode causes LED8 to toggle rapidly, indicating an invalid
sequence. To exit from this mode, press S1 to return to mode selection.
The MSP-EXP430FR5739 board is equipped with a reset switch. On reset, the device displays a short
LED lighting sequence.
