The communication interface between the AFE4403EVM board and PC is through the USB, using the
CDC profile. A one-time installation of the USB driver is required for the communication between the
AFE4403EVM and PC application.
Following the steps below ensures proper installation of the USB drivers:
1. Plugin the USB-to-mini USB cable to J4 of AFE4403EVM and the other end to the USB port on the
PC.
2. Win XP OS starts up the New Hardware Wizard to enable the user to install the USB driver for the new
hardware. The Windows 7 OS attempts to find the driver for the new hardware found automatically and
if the driver is not found, there is no pop-up message to indicate that the driver installation failed. In the
Windows 7 OS, click on Device Manager, right click on MSP430-USB example under Other devices
and click on Update Driver Software as shown in Figure 8. This step is not required for the Windows

By selecting the FFT plot, the data are displayed in the frequency domain by performing an FFT on the
channel selected. Details of the FFT (including SNR, THD, and so on) are shown in the Test Results
section located in the left side of the GUI.
Selecting the Histogram plot displays the data in a histogram format for the channel selected. The data
are arranged in the total number of histogram bins set within the tab following acquisition. The histogram
analysis (shown in the Test Results section of the GUI) is used to view the mean voltage, root mean
square (RMS) voltage, and peak-to-peak voltage.
Four plot modes can be selected: Single Plot mode, Double Plot mode, Three Plot mode and Four Plot
mode. In Single Plot mode, only one plot (Time, FFT, or Histogram) can be viewed and analyzed for post
processing. In Double Plot mode, any two plots (Time, FFT or Histogram) can be viewed and analyzed. In
Three Plot mode, any three plots and in Four Plot mode, any four plots (Time, FFT or Histogram) can be
viewed and analyzed.
The following algorithms have been used to find the # of samples for FFT calculation:
(a) # of samples for FFT calc. which is power of 2 ≤ min ( (Data rate (sps) × N where N is the value in the
Show data for the last N secs column) , No. of samples )
(b) If ( (# of samples for FFT calc. == No. of samples) && (Filter Type == “None”) ) then # of samples for
FFT calc. = No. of samples
(c) If ( (# of samples for FFT calc. == No. of samples) && (Filter Type == “Notch”) ) then # of samples for
FFT calc. = No. of samples / 2. This is to allow for filter settling.
(d) If ( # of samples for FFT calc. < 32 samples ) then an error msg “Insufficient # of samples for FFT
calculation” will be displayed.
Examples:
1. No. of samples = 3
Data rate (sps) = 500
Show data for the last 5 secs
Then # of samples for FFT calc. which is power of 2 = 2048 ≤ min ( (500 × 5) , 8192 )
2. No. of samples = 8192
Data rate (sps) = 500
Show data for the last 8 secs
Then # of samples for FFT calc. which is power of 2 = 2048 ≤ min ( (500 x 8) , 8192 )
3. No. of samples = 8192
Data rate (sps) = 500
Show data for the last 20 secs
# of samples for FFT which is power of 2 = 8192 ≤ min ( (500 x 20) , 8192 )
Since (# of samples for FFT calc. == No. of samples) and if (Filter Type = None) then # of
samples for FFT which is power of 2 = 8192
Since (# of samples for FFT calc. == No. of samples) and if (Filter Type = Notch) then # of
samples for FFT which is power of 2 = 8192 / 2
4. No. of samples = 30
Data rate (sps) = 500
Show data for the last 1 secs
Then display Error message “Insufficient # of samples for FFT calculation” since # of samples
for FFT which is power of 2 = 16 ≤ min ( (500 × 1) , 30 )
5. No. of samples = 32
Data rate (sps) = 500
Show data for the last 2 secs
# of samples for FFT which is power of 2 = 32 ≤ min ( (500 × 2) , 32 )
Since (# of samples for FFT calc. == No. of samples) and If (Filter Type = None) then # of
samples for FFT calc. which is power of 2 = 32
Since (# of samples for FFT calc. == No. of samples) and If (Filter Type = Notch) then an error
msg “Insufficient # of samples for FFT calculation” will be displayed since # of samples for FFT
calc. which is power of 2 = (32 / 2) < 32 samples

Power Supply
AFE4403 can operate from 2.0- to 3.6-V Rx analog supply (RX_ANA_SUP), 2.0- to 3.6-V Rx digital supply
(RX_DIG_SUP), 3.0- to 5.25-V Tx Control supply (TX_CTRL_SUP) and LED driver supply
(LED_DRV_SUP).
The power for the board is derived from the USB input (J4) through a forward-biased diode (D5) to avoid
reverse current flow. The USB data bus is ESD protected using TI’s ESD protection diode array
TPD4E004DRYR (U7). The USB VBUS is fed to the integrated Li-ion linear charger and system powerpath management module, BQ24032ARHLR (U12), which generates greater than 4.2-V output
(VCC_BAT). This output is fed to TI’s low-input boost converter with integrated power diode and
input/output isolation, TPS61093 (U9), for generating a boosted voltage of 8.97 V. This output is fed to
low-noise voltage regulator LP3878-ADJ (U8) for generating 5 V for the LED_DRV_SUP and
TX_CTRL_SUP. The boost converter output is also fed to the ultralow-noise linear voltage regulator
TPS7A4901DGN (U13) for generating 3 V for the RX_ANA_SUP and RX_DIG_SUP. The boost converter
output is also fed to the ultralow-noise linear voltage regulator TPS7A4901DGN (U14) for generating 3 V
for MSP_DVCC and MSP_AVCC.
Test point and series jumper resistors are provided to make sure the power supplies to the board are
correct. The corresponding voltages on AFE4403EVM are given in Table 2.

(c) Place the sensor side of the sensor board on the wrist and tie it snugly. Figure 45 shows the sensor
board being held with a velcro strap. Holding the sensor down with a finger is not recommended
because a high level of motion noise is likely to occur due to small movements and changes in
pressure.

AFE4403EVM FAQs
10.1 EVM communicating with the PC application
A quick and simple check to verify serial register write operation is to put the AFE4403 in power-down
mode. Follow the sequence to check if the GUI is communicating with the EVM.
• In Device Configuration→Global Settings tab, select Powerdown_AFE
• This powers down the AFE and the VCM output voltage of the AFE drops to 0 V
• VCM is measured at the VCM_AFE serial jumper resistor R28 on the board
10.2 ADC_RDY signal
After executing the GUI, observe the ADC_RDY waveform at series jumper resistor R26.This should be at
the same frequency as the PRF. Figure 47 shows the ADC_RDY waveform at 500-Hz PRF.

10.4 Diagnostics
The device includes diagnostics to detect open or short conditions of the LED and photo-sensor, LED
current profile feedback, and cable on or off detection. The EVM supports the diagnostic feature of the
device.
The diagnostic feature is enabled from the Global Settings under the Device Configuration tab. Clicking
the Diagnostic Enable button enables the diagnostic function and once the diagnostic function is
completed, the status of the fault flags are updated on the Global Settings tab. Figure 50 shows the
diagnostic mode fault flags when no sensor was connected to the EVM.
Figure 50. Diagnostic Feature Fault Flags with No Sensor Connected to the EVM
10.5 Automation of Register Read and Write Operations
Refer to the Scripting document located in the Documentation directory for detailed instruction on how to
use automation functions for register read and write operations.
Documentation directory is located at the following location:
• On a Windows XP machine – C:\Program Files\Texas Instruments\AFE4403EVM GUI\Documentation
• On a Windows 7 machine – C:\Program Files(x86)\Texas Instruments\AFE4403EVM

Figure 51. Setting Font Size on Windows 7 Operating System
10.7 Windows 8 Support for Device GUIs
At GUI Start up, sometimes the GUI might show a broken arrow as seen in Figure 52. One of the reasons
for this issue may be due to a missing update of .NET FRAMEWORK 3.5 (includes .NET 2.0 and .NET
3.0).
Figure 52. Broken Arrow Error
The .NET FRAMWORK 3.5 is needed for the GUI to:
• Check if Python is Installed
• Checking and setting environment variables needed for the scripting feature in the GUI
Points to Remember:
• There is no download for the .NET Framework 3.5 for Windows 8 or Windows 8.1. The user must
enable the .NET Framework 3.5 in Control Panel by following the instructions provided in this article.

Use the .NET Framework 3.5 for apps built for versions 2.0 and 3.0 as well as 3.5.
Installing a Windows language pack before installing the .NET Framework 3.5 will cause the .NET
Framework 3.5 installation to fail. Install the .NET Framework 3.5 before installing any Windows
language packs. (Source: http://msdn.microsoft.com/library/hh506443(v=VS.110).aspx)
There are two methods to resolve this.
10.7.1
Method 1 (Enabling the .NET Framework 3.5 in Control Panel)
In Control Panel, choose Programs and Features, choose Turn Windows features on or off, and then
select the .NET Framework 3.5 (includes .NET 2.0 and 3.0) check box. This option requires an Internet
connection. The user does not need to select the child items.

10.8 COM Port
It has been observed that on certain machines, the GUI will not work for lower COM ports. When the GUI
and the USB drivers are installed correctly and the Device Manager shows the AFE44x0SPO2EVM
recognized as a virtual COM port, but the GUI cannot establish communication to the AFE44x0SPO2EVM
and shows the Device Communication Error, change the COM port to a higher number (greater than 25).

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
