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.

2.2.2 Using Mode 1 –FRAM High Speed Writes
Mode 1 is entered by pressing S1 once, followed by S2. On entry, LED8 through LED1 light up
sequentially to display the speed of FRAM writes.
Every time the LED1 through LED8 sequence is completed, 800KB are written to FRAM. In this mode,
FRAM is bring written to at about 1.8MB per second. In comparison, a full-speed write to flash can
achieve speeds of approximately 13kB per second.
Figure 2. Comparing Write Speeds When Writing to Nonvolatile Memory
(MSP430FR5739 FRAM vs MSP430F2274 Flash)
Note that the code is optimized for power and not speed. FRAM memory blocks can be written at speeds
greater than 8MB per second depending on how the code is optimized. See the application report
Achieving High-Speed FRAM Writes Using the MSP430FR5739 for more details.
On entering Mode 1, the address of the FRAM scratchpad location is calculated. For the User Experience
demo, the scratchpad location starts at 0xD400 and ends at 0xF000. This location can be modified in the
header file FR_EXP.h. Note that when changing this location, it is important to first check the code space
requirements in the map file to ensure that the FRAM scratchpad area does not overlap with the
application code. Different compilers and optimization settings may impact the placement of the
application code. If any overlap occurs, the application code may be overwritten in Mode 1, which can
cause the demo to fail.
In Mode 1, the system main clock is configured to use the DCO set to 8 MHz. A function that performs
long-word writes to FRAM is called continuously inside a while loop. Each time the FRAM_Write() function
in FR_EXP.c is called, 512 bytes are written. This number was chosen arbitrarily to mimic flash segments,
and there are no restrictions on the number of FRAM bytes that can be written at once. While in Mode 1,
the LED sequence changes every time 100kB are written. For example, after the first 100KB are written,
LED8 is turned on; after the next 100kB are written, LED8 and LED7 are turned on; and so on. The
sequence completes when all eight LEDs are turned on, after which the process rolls over and starts
again from LED8.
Also, after every 100kB, a UART data transmission occurs. This data is sent to the PC via a back-channel
UART and is used to calculate the FRAM write speed and endurance information that is displayed in the
PC GUI. The raw data can also be viewed directly using a PC application such as HyperTerminal.

2.2.2.1 Measuring Current on the MSP-EXP430FR5739
While measuring the active power in a mode, the LEDs should be turned off and the UART transmissions
should be halted. This is done by pressing switch S2 while inside the mode. Switch S2 toggles the display
settings, turning them on or off as needed. Turning the display off allows the user to isolate and measure
the current consumption of the MSP430 device when executing instructions at a clock speed of 8 MHz
and writing to FRAM. In bench tests, the MSP430 IDVCC was measured at approximately 800 µA.
Note that, because of the nature of the FRAM cache, the number of accesses to FRAM memory can
greatly impact the active power consumption. Unoptimized code that performs a higher number of
accesses to FRAM can cause an increase in the measured current. It is advisable to review the compiler
settings when setting up a project using IDEs such as CCS or IAR to ensure the most efficient code and,
hence, the least active power.
The project that accompanies this document (see Section 2.1) uses a level 1 optimization setting in both
IAR and CCS that is one step higher than the default optimization levels.
As mentioned previously, when measuring the ICC on the board, it is important to isolate the current
consumption by the MSP430FR5739 only. The measurement can be done when the board is powered via
USB or externally via a battery. When powering via the USB, it is recommended to disconnect the
emulation portion from the MSP430FR5739 device. This can be done by removing jumpers TXD, RXD,
Reset, and Test on J3. A multimeter can be used to measure the current into the MSP430FR5739 VCC by
removing the VCC jumper and placing the multimeter leads in series.
An alternate approach requires powering the board externally via the VCC and GND connection and
disconnecting the USB cable from the board. In this case, the multimeter can be placed in series to VCC by
removing the MSP_PWR jumper.
These recommendations hold true when measuring IDVCC in all four modes.
2.2.2.2 Displaying Results on the PC GUI
The GUI associated with this document provides details on the time elapsed in the mode, number of bytes
written, speed of FRAM, and the endurance of FRAM emulated over a 512 byte FRAM block.
The endurance is calculated based on the 1014 program/erase cycles for the MSP430FR5739. Because
the GUI updates every one minute, the scale of reduction of FRAM endurance is very small. A more
obvious decline in endurance can be observed in Mode 2 when the endurance reduction when using flash
is emulated.
2.2.3 Using Mode 2 –Emulating the Speed of Flash Writes
Mode 2 is entered by pressing S1 twice, followed by S2. In this mode, the maximum speed at which flash
can be written to (at a 100% active duty cycle) is emulated on FRAM.
Similar to Mode 1, on entry into Mode 2, LED8 through LED1 light up sequentially to display the speed of
emulated flash writes. Every time the LED1 through LED8 sequence is completed, an 800KB write to flash
is emulated. In this mode, FRAM is written to at approximately 12 kBps. The entire sequence requires
approximately 80 seconds, so the demo should be observed for more than one minute to see the LED
sequence roll over.
NOTE: The time to run this sequence varies depending on the frequency source to the interval timer
(that is, the VLO).
The test uses the same scratchpad FRAM memory as Mode 1 and the same system setup. In this mode,
after every 2KB of memory is written, a UART packet is transmitted to the PC GUI to allow it to calculate
speed and endurance information.
When measuring the average power the methodology described in Section 2.2.2.1 needs to be followed.

2.2.3.1 The Math Behind Mode 2
The MSP430F2274 device was used as a benchmark device to calculate the maximum flash write speed.
For a 512-byte block of flash, the following parameters were obtained from the MSP430F2274 data sheet:
Segment erase time = 4819 ×tFTG = 16 ms
Where, tFTG =1/fFTG ≈1 / 300 kHz
512 bytes write time ≈51.2 ms
Total time to write to 512 bytes ≈67.2 ms
Time to write to 100KB = 6.72 seconds, which calculates to 14.8 kBps
When measuring the speed of continuous flash writes on the bench, the observed speed is approximately
12 kBps, because the code execution overhead is added to the time calculated above.
This write speed is emulated with the FRAM device by maintaining a low active duty cycle and performing
one 512 byte block write every 40 ms.
Number of writes per second = 1 / 40 ms = 25
Number of bytes written per second = 512 ×25 = 12.800 kBps
The timing of the FRAM write is controlled by the VLO clock.
From these bench tests, it can be seen that writing 12 kBps to flash requires nearly 100% duty cycle,
while writing the same speed to FRAM requires less than 1% duty cycle. The rest of the time, the FRAM
device is in shutdown mode (LPM4), which results in an average current of less than 10 µA. In
comparison, for a similar write speed, flash-based MCUs can require average current up to 2.2 mA.
Figure 3. Comparing Average Power When Writing to Nonvolatile Memory at 13 kBps
(MSP430FR5739 FRAM vs MSP430F2274 Flash)
2.2.3.2 Displaying Results on the PC GUI
When in Mode 2, the GUI provides details on the time elapsed in the mode, number of bytes written,
speed of emulated flash writes, and the endurance emulated over a 512 byte flash block.
The endurance is calculated based on the 104program/erase cycles (minimum) for the MSP430F2274. If
a 512-byte block on a flash device were written to at a speed of 12.5 kBps (that is, 25 times per second),
the endurance would exceed the minimum limit in 10000/25 or 6.6 minutes.
Note that the MSP-EXP430FR5739 board only emulates this test to demonstrate a comparison in speed
and endurance between FRAM and flash; it does not perform the test on an actual flash device.

3 Axis Accelerometer
www.ti.com MSP-EXP430FR5739 User Experience Demo
2.2.4 Using Mode 3 –Accelerometer Demo
Mode 3 is entered by pressing switch S1 three times, followed by switch S2.
Upon entering this mode, the on-board accelerometer (see Figure 4) is calibrated. To aid this calibration
process, it is recommended to place the board on a level surface before entering the mode.
Figure 4. On-Board Accelerometer
After the calibration sequence is completed, LED4 and LED5 are turned on. When tilting the board in an
upward or downward direction, the LEDs follow the direction of the tilt. S2 toggles the display on and off,
similar to other modes.
Mode 3 also writes the sampled data from the ADC to the FRAM in real time with no wait states or extra
cycles spent on setting up the FRAM. This can be observed in the ADC interrupt service routine. The
sampling takes place at more than 15k samples per second. At this speed, flash devices require that the
data be buffered in RAM before writing to flash. In FRAM devices, the only bottleneck is the speed at
which the ADC can sample, not the writes to nonvolatile memory.
2.2.4.1 Displaying Results on the PC GUI
When in the accelerometer mode, the GUI mimics the LEDs that are lit up on the Experimenter Board and
are a reflection of the tilt of the board.

NTC Thermistor
MSP-EXP430FR5739 User Experience Demo www.ti.com
2.2.5 Using Mode 4 –Temperature Sensor Demo
Mode 4 is entered by pressing switch S1 four times, followed by switch S2.
Upon entering this mode, the on-board thermistor (see Figure 5) is calibrated.
Figure 5. On-Board NTC Thermistor
After the calibration sequence is completed, LED4 and LED5 are turned on. When the NTC resistor is
heated (for example, by placing a finger on it), LED3 through LED1 are turned on sequentially. When the
NTC is cooled (for example, by using a freeze spay or a keyboard dust remover that uses compressed air)
LED5 through LED8 are turned on sequentially.
Similar to Mode 3, Mode 4 also writes the sampled data from the ADC to the FRAM in real time with no
wait states or extra cycles spent on setting up the FRAM. This can be observed in the ADC interrupt
service routine. The sampling takes place at more than 15k samples per second. At this speed, flash
devices require that the data be buffered in RAM before writing to flash. In FRAM devices, the only
bottleneck is the speed at which the ADC can sample, not the writes to nonvolatile memory.
2.2.5.1 Displaying Results on the PC GUI
When in the temperature sense mode, the GUI mimics the LEDs that are lit up on the Experimenter Board
and are a reflection of the thermistor's ambient temperature measurement.
