Introduction
The MSP430FR2311 LaunchPad™ Development Kit (MSP-EXP430FR2311) is an easy-to-use evaluation
module (EVM) for the MSP430FR2311 MCU. It contains everything needed to start developing on the
ultra-low-power MSP430FRx FRAM microcontroller platform, including onboard emulation for
programming, debugging, and energy measurements. The board features onboard buttons and LEDs for
quick integration of a simple user interface as well as an analog photodiode to showcase the integrated
analog peripherals. The MSP430FR2311 MCU device is the world's first MCU with a configurable lowleakage current sense amplifier, with 50-pA current leakage and 4KB of embedded FRAM (ferroelectric
random access memory), a nonvolatile memory known for its ultra-low power, high endurance, and highspeed write access.
Rapid prototyping is simplified by the 20-pin BoosterPack™ plug-in module headers, which support a wide
range of available BoosterPack plug-in modules. You can quickly add features like wireless connectivity,
graphical displays, environmental sensing, and much more. Design your own BoosterPack plug-in module
or choose among many already available from TI and third-party developers.
The out-of-box experience provided with the MSP-EXP430FR2311 MCU LaunchPad development kit
features the onboard analog photodiode. The current from the photodiode is converted by an integrated
operational amplifier to a voltage. That voltage is then sensed by an analog-to-digital converter and fed to
a timer module to pulse width modulate LED2. As more light hits the photodiode, LED2 brightens, and as
less light hits the photodiode, LED2 dims.
Free software development tools are also available, such as TI's Eclipse-based Code Composer Studio™
integrated development environment (IDE) and IAR Embedded Workbench® IDE. Both of these IDEs
support EnergyTrace™ technology for real-time power profiling and debugging when paired with the
MSP430FR2311 MCU LaunchPad development kit. More information about the LaunchPad development
kit, the supported BoosterPack plug-in modules, and available resources can be found on TI's LaunchPad
ecosystem portal.
The MSP-EXP430FR2311 is based on Experimental Silicon. The MSP430FR2311IPW20 device used in
this version of the MSP-EXP430FR2311 is a prototype device and has not met or completed Texas
Instruments internal reliability qualification requirements. The device used in this development kit is for
prototyping purposes only and is not intended to be used in production systems. Therefore, the device is
used on an "as is" basis and Texas Instruments makes no warranty of fitness for a specific purpose.

First Steps: Out-of-Box Experience
An easy way to get familiar with the EVM is by using its preprogrammed out-of-box code. This code
demonstrates some key features from a user level.
1.4.1
Connecting to the Computer
Connect the LaunchPad development kit using the included USB cable to a computer. A green power LED
should illuminate. For proper operation, drivers are needed. TI recommends installing the TI Code
Composer Studio IDE or IAR Embedded Workbench for MSP430 IDE. Drivers are also available at
ti.com/MSPdrivers.
1.4.2
Running the Out-of-Box Demo
When connected to your computer, the LaunchPad development kit powers up and LED2 dims based on
the amount of ambient light hitting the photo diode, D1. Use a light source such as a flashlight or desk
lamp to illuminate D1 and the brightness of LED2 should increase depending on the intensity of the light
source.
1.5
Next Steps: Looking Into the Provided Code
After the EVM features have been explored, the fun can begin. It's time to open an integrated
development environment and start editing the code examples. Refer to Section 4 for available IDEs and
where to download them.
The quickest way to get started using the LaunchPad development kit is to use TI's Cloud Development
Tools, dev.ti.com. The cloud-based Resource Explorer provides access to all of the examples and
resources in MSPWare™ software. Code Composer Studio IDE Cloud is a simple Cloud-based IDE that
enables developing and running applications on the LaunchPad development kit.
The out-of-box source code and more code examples are provided for download from
www.ti.com/tool/msp-exp430fr2311. Code is licensed under BSD, and TI encourages reuse and
modifications to fit specific needs.
Section 3 describes all functions in detail and provides a project structure to help familiarize you with the
code.
Using the onboard eZ-FET emulator, debugging and downloading new code is simple. A USB connection
between the EVM and a PC through the provided USB cable is all that is needed.

eZ-FET Onboard Emulator With EnergyTrace™ Software
To keep development easy and cost effective, TI's LaunchPad development kits integrate an onboard
emulator, which eliminates the need for expensive programmers. The MSP-EXP430FR2311 has the eZFET emulator (see Figure 5), which is a simple and low-cost debugger that supports all MSP430 MCU
derivatives.
Figure 5. eZ-FET Emulator
The MSP-EXP430FR2311 MCU LaunchPad development kit features EnergyTrace software. The
EnergyTrace software functionality varies across the MSP portfolio.

The eZ-FET also provides a "backchannel" UART-over-USB connection with the host, which can be very
useful during debugging and for easy communication with a PC. The provided UART supports hardware
flow control (RTS and CTS), although by default these signals are not connected to the target.
The dotted line through J101 shown in Figure 5 divides the eZ-FET emulator from the target area. The
signals that cross this line can be disconnected by jumpers on J101, the isolation jumper block. More
details on the isolation jumper block are in Section 2.2.3.
The eZ-FET hardware can be found in the schematics in Section 6 and in the accompanying hardware
design files. The software and more information about the debugger can be found on the eZ-FET wiki.

Emulator Connection: Isolation Jumper Block
The isolation jumper block at jumper J101 allows the user to connect or disconnect signals that cross from
the eZ-FET domain into the MSP430FR2311 MCU target domain. This includes eZ-FET Spy-Bi-Wire
signals, application UART signals, and 3.3-V and 5-V power.
Reasons to open these connections:
• To remove any and all influence from the eZ-FET emulator for high-accuracy target power
measurements
• To control 3-V and 5-V power flow between the eZ-FET and target domains
• To expose the target microcontroller pins for other use than onboard debugging and application UART
communication
• To expose the programming and UART interface of the eZ-FET so that it can be used for devices other
than the onboard microcontroller

Application (or "Backchannel") UART
The backchannel UART allows communication with the USB host that is not part of the target application's
main functionality. This is very useful during development, and also provides a communication channel to
the PC host side. This can be used to create graphical user interfaces (GUIs) and other programs on the
PC that communicate with the LaunchPad development kit.
Figure 6 shows the pathway of the backchannel UART. The backchannel UART is the UART on
eUSCI_A0.
On the host side, a virtual COM port for the application backchannel UART is generated when the
LaunchPad development kit enumerates on the host. You can use any PC application that interfaces with
COM ports, including terminal applications like Hyperterminal or Docklight, to open this port and
communicate with the target application. You need to identify the COM port for the backchannel. On
Windows PCs, Device Manager can assist.

The backchannel UART is the "MSP Application UART1" port. In this case, Figure 7 shows COM13, but
this port can vary from one host PC to the next. After you identify the correct COM port, configure it in
your host application according to its documentation. You can then open the port and begin
communication to it from the host.
On the target MSP430FR2311 MCU side, the backchannel is connected to the eUSCI_A0 module. The
eZ-FET has a configurable baud rate; therefore, it is important that the PC application configures the baud
rate to be the same as what is configured on the eUSCI_A0.
2.2.5
Special Features
2.2.5.1
Smart Analog Combo (SAC)
The MSP430FR2311 MCU LaunchPad development kit features pins to access the smart analog combo
on the device. These pins are accessed on jumpers J7, J8 and J9 where the smart analog combo
operational amplifier is connected to the onboard photodiode circuit. These pins are also connected to the
BoosterPack plug-in module header pins. For applications that use the SAC and a connected BoosterPack
plug-in module, be sure to check for any pin conflicts. The photodiode circuit can be disconnected from
the SAC using jumpers J7, J8 and J9. The user can connect an external analog sensor circuit to the SAC
by removing jumpers J7, J8 and J9 and connecting their circuit to the appropriate header pins through the
BoosterPack plug-in module headers or the jumpers near the light sensor circuit.
To adjust the light sensor circuits' sensitivity the user can adjust either the software or the hardware. By
changing the value of R3 and C6 the user can change the operational amplifiers low-pass filter and
sensitivity to the photodiodes current. The user can also adjust the calculations performed in the software
to adjust the sensitivity of the circuit to their desired level.
2.3
Power
The board was designed to accommodate various powering methods, including through the onboard eZFET as well as external or BoosterPack power (see Figure 8).

2.3.1
eZ-FET USB Power
The most common power-supply scenario is from USB through the eZ-FET debugger. This provides 5-V
power from the USB and also regulates this power rail to 3.3 V for eZ-FET operation and 3.3 V to the
target side of the LaunchPad development kit. Power from the eZ-FET is controlled by jumper J101. For
3.3 V, make sure that a jumper is connected across the J101 3V3 terminal.
2.3.2
BoosterPack Plug-In-Module and External Power Supply
Header J5 is present on the board to supply external power directly. It is important to comply with the
device voltage operation specifications when supplying external power. The MSP430FR2311 MCU has an
operating range of 1.8 V to 3.6 V. More information can be found in MSP430FR231x Mixed-Signal
Microcontrollers.
2.4
Measure MSP430 MCU Current Draw
To measure the current draw of the MSP430FR2311 MCU using a multi-meter, use the 3V3 jumper on the
jumper isolation block. The current measured includes the target device and any current drawn through
the BoosterPack headers.
To measure ultra-low power, follow these steps:
1. Remove the 3V3 jumper in the isolation block, and attach an ammeter across this jumper.
2. Consider the effect that the backchannel UART and any circuitry attached to the MSP430FR2311 MCU
may have on current draw. Consider disconnecting these at the isolation jumper block, or at least
consider their current sinking and sourcing capability in the final measurement.
3. Make sure there are no floating inputs/outputs (I/Os). These cause unnecessary extra current draw.
Every I/O should either be driven out or, if it is an input, should be pulled or driven to a high or low
level.
4. Begin target execution.
5. Measure the current. Keep in mind that if the current levels are fluctuating, it may be difficult to get a
stable measurement. It is easier to measure quiescent states.
EnergyTrace software allows you to compare various current profiles and better optimize your energy
performance!
2.5
Clocking
The MSP-EXP430FR2311 provides an input for an external clock in addition to the internal clocks in the
device. No crystal is populated by default to allow all pins to connect to the BoosterPack header. The user
can choose to populate any 32.768 kHz crystal that will fit onto the provided footprint. One option is
recommended below:
• Y1: 32-kHz Epson FC-135R 12.5pF crystal, Part #: X1A0001410014
The 32-kHz crystal allows for lower LPM3 sleep currents than do the other low-frequency clock sources.
Therefore, the presence of the crystal allows the full range of low-power modes to be used. If using the
external Y1 crystal footprint the user will need to remove the 0-ohm resistors R4 and R5 and populate C2
and C3 with the appropriate tuning capacitors for the crystal that is used.
The internal clocks in the device default to the following configuration:
• MCLK: DCO at 1 MHz
• SMCLK: DCO at 1 MHz
• ACLK: REFO at 32.768 kHz
For more information about configuring internal clocks and using the external oscillators, see the
MSP430FR4xx and MSP430FR2xx Family User's Guide.

Using the eZ-FET Emulator With a Different Target
The eZ-FET emulator on the LaunchPad development kit can interface to most MSP430 MCU derivative
devices, not just the onboard MSP430FR2311 MCU target device.
To do this, disconnect every jumper in the isolation jumper block. This is necessary, because the emulator
cannot connect to more than one target at a time over the Spy-Bi-Wire (SBW) connection.
Next, make sure the target board has proper connections for SBW. Note that to be compatible with SBW,
the capacitor on RST/SBWTDIO cannot be greater than 2.2 nF. The documentation for designing MSP430
MCU JTAG interface circuitry is the MSP430 Hardware Tools User's Guide.
Finally, wire together these signals from the emulator side of the isolation jumper block to the target
hardware:
• 5 V (if 5 V is needed)
• 3.3 V
• GND
• SBWTDIO
• SBWTCK
• TXD (if the UART backchannel is to be used)
• RXD (if the UART backchannel is to be used)
This wiring can be done either with jumper wires or by designing the board with a connector that plugs into
the isolation jumper block.
2.7
BoosterPack Plug-in Module Pinout
The LaunchPad development kit adheres to the 20-pin LaunchPad pinout standard. A standard was
created to aid compatibility between the LaunchPad development kit and BoosterPack plug-in module
tools across the TI ecosystem.
The 40-pin standard is compatible with the 20-pin standard that is used by other LaunchPad development
kit's like the MSP-EXP430FR6989. This allows some subset of functionality of 40-pin BoosterPack
modules to be used with 20-pin LaunchPad development kits.
While most BoosterPack plug-in modules are compliant with the standard, some are not. The MSPEXP430FR2311 MCU LaunchPad development kit is compatible with all 20-pin BoosterPacks plug-in
modules that are compliant with the standard. If the reseller or owner of the BoosterPack plug-in module
does not explicitly indicate compatibility with the MSP-EXP430FR2311 MCU LaunchPad development kit,
compare the schematic of the candidate BoosterPack with the LaunchPad to ensure compatibility. Keep in
mind that sometimes conflicts can be resolved by changing the MSP430FR2311 MCU pin function
configuration in software. More information about compatibility can also be found at
www.ti.com/launchpad.
Figure 9 shows the 20-pin pinout of the MSP430FR2311 MCU LaunchPad development kit.
Note that software configuration of the pin functions plays a role in compatibility. The LaunchPad
development kit side of the dashed line in Figure 9 shows all of the functions for which the
MSP430FR2311 MCU's pins can be configured. This can also be seen in the MSP430FR2311 MCU data
sheet. The BoosterPack plug-in module side of the dashed line shows the standard. The LaunchPad
development kit function whose color matches the BoosterPack plug-in module function shows the specific
software-configurable function by which the MSP430FR2311 LaunchPad development kit adheres to the
standard.

Out-of-Box Software Example
This section describes the functionality and structure of the out-of-box software that is preloaded on the
EVM.
This demo shows how to use the op-amp module, combined with the timer, ADC, and LED, to implement
a simple light sensor circuit for ultra-low-power applications.
Upon powering up the out-of-box demo, LED1 will toggle at startup and then LED2 will dim based on the
amount of ambient light in the area. If the user covers the photo diode, D1, with a piece of paper or their
hand the brightness of LED2 should dim based on the amount of light. If the user illuminates the photo
diode with a light source LED2 should increase in brightness until the ADC saturates and the LED reaches
full brightness. The current ADC reading is saved to FRAM memory before the device re-enters LPM3.

FAQ
Q: I can't get the backchannel UART to connect. What's wrong?
A:
•
•
•
Check the following:
Do the baud rate in the host's terminal application and the eUSCI settings match?
Are the appropriate jumpers in place on the isolation jumper block?
Probe on RXD and send data from the host. If you don't see data, it might be a problem on the host
side.
• Probe on TXD while sending data from the MSP. If you don't see data, it might be a configuration
problem with the eUSCI module.
• Consider the use of the hardware flow control lines (especially for higher baud rates).
Q: The MSP G2 LaunchPad development kit had a socket, allowing me change the target device.
Why doesn't this LaunchPad development kit use one?
A: This LaunchPad development kit provides more functionality, and this means using a device with more
pins. Sockets for devices with this many pins are too expensive for the target price of the LaunchPad
development kit.
