General Description
This application note describes the usage of the AS5x6y Evaluation Software for programming the
AS5161, AS5162, AS5261 and AS5262 magnetic position sensors.

AS5x6y Evaluation Software Installation
First download and install the latest version of the AS5x6y Evaluation Software from our webpage
at www.ams.com.
The software is written in LabVIEW. To be able to run the software properly the latest NI LabVIEW
Run-Time Engine and NI VISA Run-Time Engine have to be installed on the computer. This can be
downloaded for free from the National Instruments webpage at www.ni.com.
After running these installers it should be possible to run the software without any errors.

Programming Options
Either the AS5xxx-EK-PB (UART) Programmer or the SD4Y Production Programmer can be used.
When using the SD4Y programmer additionally the UPROG Relay Board has to be used.

Hardware Setup
1. Start the AS5x6y Evaluation Software.
Figure 2: Starting screen
2. Depending on the Programming Hardware please select the proper one from the dropdown
menu and follow the instructions.
A. When using the UART Programmer please choose the right COM Port and enter the
Baude Rate (typically 9600 baude)
B. When using the SD4Y Programmer choose the right COM Port and press the Connect
Button. When successfully connected to SD4Y the current Firmware appears.

Programming Procedure
1. Go to “AS5x6y Bottom Die” tab
Figure 4: AS5x6y Bottom Die
2. Enter start angle T1. Either manually enter the position or move the magnet to initial position
and click the “GET” button.
3. Enter final angle T2. Either manually enter the position or move the magnet to the final position
and click the “GET” button.

4. In section “Slope Parameters” enter the characteristic of your output.
5. Enter T1Y in Volt. T1Y is the output voltage at the initial magnet position T1.
6. Enter T2Y in Volt. T2Y is the output voltage at the final magnet position T2.
7. Enter CLL in Volt. Clamping Level Low is the output voltage for the lower failure band.
8. Enter CLH in Volt. Clamping Level High is the output voltage for the higher failure band.
9. Enter the required quadrant mode.
There is the choice of 4 quadrant modes with following limitations:
1 quadrant:
full 360°
2 quadrants:
max. 180° / quadrant
3 quadrants:
max. 120° / quadrant
4 quadrants:
max. 90° / quadrant
10. Enter VDD Ratio. If the supply voltage at programming deviates from 5V this parameter has to
be set. Enter this parameter as a ratio of 5V / VDD_Prog. When there is no deviation from 5V
use 1,00.
11. Click „Calculate“. The DLL will calculate the programming data in the background and the graph
will show a preview of the programmed output slope.

12. When using AS5161 or AS5261 (PWM) please move to step 22.
13. Click “Enable DAC Calibration”
14. Click the “Start DAC Calibration” button.
15. Connect a digital voltmeter to the OUT pin and press OK.
16. Measure T1 value with voltmeter, write into the box and press enter.

17. A pop-up window appears. Press OK and the device will be reset.
18. Measure T2 value with voltmeter and write value into the box.
19. A pop-up window appears. Press OK and the device will be reset.
20. Press again “Calculate” and the “Programming Data” will slightly be corrected.

21. When using AS5261 or AS5262 dual-die device repeat the steps 1 to 20 again for the Top Die.
22. Go to “Programming” tab.
Figure 6: Programming tab
23. In this tab some more settings like “Customer ID”, “Filter Configuration” and “Airgap Selection”
can be done.

24. Select the wanted “Filter Configuration” from the drop down menu.
25. Select wanted “Airgap Selection” from the drop down menu. This sets your magnetic input
range from 30 – 70 mT in “Normal Range” and from 10 – 90 mT in “Extended Range”. Extended
Range also means increased sensor output noise.
26. When using AS5161 or AS5261 also select the PWM frequency from the drop down menu.
27. At this point the device can either be switched to “Pass2Function” mode or you can burn the
OTP fuses. When using the “Pass2Function” mode the device is only programmed temporarily
until it is reset again. When clicking the “FUSE” Button the OTP fuses are burned and the
device is permanently programmed. For permanent programming go to step 33.
28. To set the device to “Pass2Function” mode, DO NOT set the “Customer Lock” bit.
29. Click “Write” Button.
30. Click “Read” Button.

31. Check if Write/Read checksum is correct.
32. Click “Pass2Function” button. The device switches from communication mode to functional
mode.
Caution! – Permanent programming beyond this point
33. For permanently programming of OTP fuses set the “Customer Lock” bit.
34. Click “Write” Button.
35. Click “Read” Button
36. Check if Write/Read checksum is correct.
37. Click “FUSE” button.
38. A pop-up window will appear.
39. If you press OK the OTP fuses of the device will be burned and successful burning will be
indicated in the “Programming Info” Box. This box will also show if there was an error during the
burn process.
