2 Hardware Description
2.1 Block Diagram
Figure 6 shows the EVM block diagram.
Figure 6. RF430FRL152HEVM Block Diagram
• The EVM board can be powered by RF scavenged energy, battery, FET emulator tool, or USB power.
When powered through the USB connection or an MSP-FET emulation tool, switch S6 must be set to
"Supply". If the EVM is powered by scavenged RF energy or a battery, switch S6 must be set to
"Battery".
• Level translators are used on I2C, SPI, and FET emulator interfaces.
• The power (green) LED should turns on only when the board is powered by a USB connection.
• Jumper SV7 is needed to bypass the internal battery switch and provide power directly to the core.
This jumper should be populated for most use cases.
• When the EVM is powered by the USB connection, the Alarm LED briefly flashes at power-up or stays
illuminated if there is an interrupt from the RF430FRL152H. It is normal for the Alarm LED to stay lit
during MSP-FET tool programming.

Figure 7. RF430FRL152HEVM Hardware
2.3 Hardware Configurations
2.3.1 Passive (Unpowered) Operation
In this mode, the RF430FRL152H is powered entirely from the RF field generated by the reader.
1. Set S6 to "Battery".
2. Set S3 to "S" (slave mode).
3. Make sure that USB and the MSP-FET emulation tool are not connected.
4. Place the EVM antenna on top of a NFC reader/writer to communicate.
Neither the "Alarm" or the "Power" LEDs illuminate in this mode of operation at any time. At this time a
NFC/RFID reader may be used to communicate to the RF430FRL152HEVM.
2.3.2 Debugging or Programming
The following instructions show how to program the FRAM memory or debug the RF430FRL152H using a
MSP-FET emulation tool. In this configuration the EVM is powered by the MSP-FET emulation tool.
1. Set switch S6 (near the BoosterPack plug-in module headers) to "Supply".
2. Connect the MSP-FET430 emulation tool to the JTAG header, SV2.
3. Start a debug session using IAR or CSS IDE.
4. Connection with the USB cable is not necessary for debugging or programming the RF430FRL152H.
Note: The Alarm LED may be illuminated during the debugging process if the USB cable is connected.
This is normal behavior.
Note: If the USB cable is not connected, the power LED (U5) and the Alarm LED (7) are not illuminated
even if the emulation tool is connected. This is normal behavior.
The MSP-FET emulation tool can be used to program or debug the EVM at this point.

2.3.3 Using a BoosterPack Plug-in Module or Digital Sensors
An example of this use case is using the Sensor Hub BoosterPack plug-in module. In this configuration
the EVM is powered by the USB connection.
1. Set switch S6 (near the BoosterPack plug-in module headers) to "Supply".
2. Set switch S3 to "M" (master mode).
3. Attach the BoosterPack plug-in module on top of the EVM, making sure it is in the correct orientation
(pin 1 on the EVM matches pin 1 on the BoosterPack plug-in module headers).
4. Connect the USB cable to either the BoosterPack plug-in module or the RF430FRL152HEVM.
Note: When the USB cable is attached, the power LED (U5) stays illuminated. The Alarm LED (U7) should
momentarily illuminate and then turn off.
Now the TRF7970AEVM can be used to communicate to the part and initiate samples of the various
sensors.
2.3.4 Using a Host Controller
In this mode, the host LaunchPad development kit is connected underneath the RF430FRL152HEVM.
Make sure the orientations match.
1. Set switch S6 (near the BoosterPack plug-in module headers) to "Supply" setting.
2. Set S3 to "S" (slave mode).
3. For a host that uses I2C, S5 and S4 determine the two least significant bits of the I2C slave address for
the RF430FRL152H. For most cases, set these switches to the "0" positions.
4. For a host that uses SPI, S5 and S4 determine the SPI mode. For most cases, set these switches to
the "0" positions.
5. Set S5 or S4 to desired setting at this time.
6. Connect the LaunchPad development kit and the EVM together.
7. Power either the LaunchPad development kit or the EVM by connecting either to a USB cable.
Note: When the USB cable is attached, the power LED (U5) stay illuminated. The Alarm LED (U7) should
momentarily illuminate and then turn off.
2.3.5 Powering the EVM Using a Battery
1. Insert an SR66 1.5-V battery into the battery holder (BAT1).
2. Note: The first time that a battery is inserted, the battery holder may be tight. Carefully holding the
board with a flat object, firmly slide in the battery. Make sure that the positive side of the battery is
facing the positive (or top) side of the battery holder.
3. Set S6 to "Battery".
4. If the battery switch is open (the battery switch is inside the RF430FRL152H), SV7 needs to have a
jumper to power the part. If the battery switch is closed, then SV7 does not need a jumper to power the
RF430FRL152H.
Note: In this mode, the alarm and power LEDs are not illuminated. The device is still powered and
operational.
Note: Also if S5, S4, or S3 positions are changed after powering the EVM, a reset is required for the
changed settings to take effect. This can be done through the PC GUI or by pressing the reset switch
(S2).
Note: If a battery is installed and another configuration (for example, debugging or using a BoosterPack
plug-in module) is required, set switch S6 to "Supply" to disconnect the battery and not drain it.

4 Overview
This section describes the meaning of each of the options on each tab. Remember, checking an option
does not immediately cause that option to be set. It is only set after a "Write" button click is performed.
Any changes that have occurred on the part, like new status, will not be visible until a "Read" button click
has been done.
4.1 Connection to the EVM
Before any configuration can be done to the device using this application, a serial connection must be
established. This can be done with the controls on the bottom of the application.
There is a drop-down list in which either a particular port can be chosen, if it is already known, or an
automatic selection can be chosen.
When this is done, click on "Connect to TRF7970AEVM". If the connection succeeds, the text of the button
changes to "Disconnect from TRF7970AEVM".
If the EVM is plugged in after the application starts, then the drop-down list does not have the currently
available COM port selection. Click on the "Update" button to update the list.
4.2 Typical Sequence
In a typical sequence (for example, to do a thermistor measurement) follow these steps. These steps are
more fully described in the RF430FRL15xH Firmware User's Guide.
1. Configure the thermistor measurement parameters:
1. Select the thermistor sensor.
2. Set how many times it needs to be sampled.
3. If sampled more than one time, select the delay between the samples.
4. Select the ADC configuration (resolution, PGA setting, and type of filter).
These settings are written to the virtual registers in the FRAM memory using RF communication.
2. Write the start bit in the control register to start the sampling process.
3. There is a delay while the sampling process is being performed.
4. After sampling is complete, the requested measurements are stored into the log memory, typically
FRAM (after the virtual registers).

One pass is sampling all of the selected sensors one time.
18. Averaging Register
Any value higher than 1 causes that many samples to be averaged into one result. Averaging mode in
the "Alarm Control" tab selects the type of averaging used per sensor.
19. Frequency Register
Selects the delay to be made in between each of the sampling passes. Note this delay must not be
less than the time to complete sampling all of the sensors one time. If it is less, then a "collision"
occurs.
20. More Registers
This advanced section is not required in most cases. However, it is described below.
Gating option to enable the external GPIO interrupt.
21. Interrupt Assert Level
The level to be driven or pulled to if there is an interrupt
22. Interrupt Drive State
Determines if the device drives an interrupt or is high impedance (user must provide the appropriate
pullup or pulldown resistor).
23. Bus Test Mode Enable
Allows access to protected memory using an I2C or SPI host.

24. Check For Unexpected Reset
If this option is selected, and an unexpected reset occurs, the reset code is logged at the end of the
logging memory.
25. Disconnect Battery At Sampling End
When the sampling process has been completed, this option causes the ROM code to open the battery
switch.
26. End of Sampling External Interrupt Enable
When the sampling process has completed, this option causes an external interrupt to be generated.
27. Voltage Levels Alert
When these are set, it indicates that the voltage levels have gone too low on a particular rail at some
point. Not self clearing.
28. BIP8 Control
Error detection for I2C or SPI protocol
29. Infinite Sampling
Samples until the "Start Sampling Process" option is unchecked.
30. Enable Watchdog
Enables the watchdog during a sampling process.
31. RAM Storage Enable
Writes sampling results into RAM memory instead of FRAM.
32. Read only this tab
Reads Gen. Device Config and populates the results on this tab.
33. Write only this tab
Writes Gen. Device Config with all of the settings on this tab.
34. Read All Tabs
Reads all of the information on all of the tabs from the virtual FRAM registers in the device using RF
and populates the fields in the tabs.
35. Write All Tabs
Writes all of the information to the virtual FRAM registers in the device over RF from all of the settings.
NOTE: Settings made on the following tabs do not take effect until a "Write only this tab" or "Write
All Tabs" button is clicked:
Gen. Device Config.
Sensor Config.
Alarm Control
Sensor Threshold Config.
Likewise, the settings on these tabs are not updated until a "Read only this tab" or "Read All
Tabs" button is clicked.

4.6 Sensor Configuration Tab
The options for the four different analog sensors can be controlled from this tab (see Figure 12). The
options can be changed only if the corresponding sensor is enabled in the "Gen. Device Config" tab.
Figure 12. Sensor Configuration Tab
1. Sensor Configuration Sensor
Allows control of the analog-to-digital configuration for a particular sensor.
2. Gain
Selects the programmable gain amplifier (PGA) before the ADC.
3. Filter Type
Select the filter to be used.
4. Oversampling
Determines the resolution and time of the sample.
5. Use Virtual Ground
If selected, raises the ADC and sensor ground level several hundred millivolts. It is recommended that
this setting is consistent for all of the sensors.
6. Initial Delay Enable / Initial Delay (ms)
Creates a delay of configured time after starting the sampling process.
7. Enable JTAG
Because JTAG is normally disabled on the device, and if there is trouble establishing a JTAG
connection, enabling this option can help establish connection. This setting takes effect only after a
reset or power cycle.
8. Number of Blocks Received
This is a counter that indicates how many ISO/IEC blocks have been received. Can be reset.
9. Sensor Skip Settings
Allows control of the duty cycle for a sensor.

4.7 Alarm Control Tab
The alarm control options for the four different analog sensors can be controlled from this tab (see
Figure 13). The options can be changed only if the corresponding sensor is enabled in the "Gen. Device
Config" tab.

1. Averaging Mode
True averaging is done only if the "Average" option is selected. The Lowest or Highest options store
only the lowest or highest, respectively, sample for the selected sensor. The number of samples done
before the result is stored is set in the "Averaging Register" setting on the "Gen. Device Config" tab.
The "First" option stores the first sample of the selected sensor. If averaging is selected, during
sampling passes after the first sample was stored, the remaining passes will skip this sensor.
2. Enable Alarm Monitor
Enables a check for high or low thresholds for a particular sensor. The results are given in the labels
below.
3. Enable Alarm Interrupt
Enables a GPIO interrupt if a high or low threshold has been exceeded. The "Enable Alarm Monitor"
must also be selected for this to take effect.
4. Stored Sample Memory
Defines the length of the logged samples memory section.
5. Total Number Of Stores
Reports how many samples were written to the log memory.
6. Sample Buffer Index
Reports the index location of the last sample stored.
7. FRAM Virtual Registers Initialized
If checked, indicates that the FRAM memory has been initialized.
8. Reset Status Flags on This Tab On Next Write
Resets all of the flags on this tab the next time the "Write" button is clicked.

9. High Threshold Monitor Enable
Enables monitoring of that particular sensor for a sample value that exceeds or is equal to the
threshold value set in "Sensor Threshold Config." tab. If the sample meets that condition, the status for
that sensor (in the same group box) changes to indicate that condition.
10. Low Threshold Monitor Enable
Enables monitoring of that particular sensor for a sample value for that is less than or equal to the
threshold value set in "Sensor Threshold Config." tab. If the sample meets that condition, the status for
that sensor (in the same group box) changes to indicate that condition.
4.8 Sensor Threshold Configuration Tab
Figure 14 shows the Sensor Threshold Configuration tab. A sensor must be enabled in the "Gen. Device
Config" tab to allow the Sensor Threshold Configuration tab to change its threshold.
Figure 14. Sensor Threshold Configuration
1. Custom Time Register
Available only if the "Frequency Register" has been set to the "Custom Time" option. Resolution is in
milliseconds.
2. High Threshold
If the sensor sample result meets or exceeds the high threshold set here, an alarm is generated.
Operation depends on settings in the "Alarm Control" tab.
3. Low Threshold
If the sensor sample result is lower or meets the low threshold set here, an alarm is generated.
Operation depends on settings in the "Alarm Control" tab.
