1 Overview
TMAG6180 and TMAG6181 are each magnetic sensors built on anisotropic magnetoresistive (AMR) sensing
technology. Typically, AMR sensors are only able to resolve 180 degree rotation, but with addtional integrated
Hall-effect sensing, each sensor produces both sine and cosine differential outputs which are used to measure
the absolute angular position of a rotating magnet. Each sensor is capable of detecting a full 360 degree rotation
unlike typical AMR sensors. TMAG6180 provides additonal outputs Q0 and Q1 which can be used to determine
the quadrant of rotation, while TMAG6181 provides a pulse width moduled (PWM) turns counter output that
increments or decrements at each quadrant change. Using the information from these outputs, extending the
180 degree output to a full 360 position calculation is possible.

TMAG6180 is installed on the top side of the EVM and TMAG6181 is installed directly opposite on the bottom.
During use with the EVM Graphical User Interface (GUI) differential outputs are sampled by an on-board
ADS8354 which transmits the output readings over SPI to the TI sensor control board (TI-SCB).

2 Hardware
The EVM is an easy-to-use platform for evaluating the main features and performance of the TMAG6180-Q1
and TMAG6181-Q1. The EVM includes a graphical user interface (GUI) used to read data from the on-board
ADS8354, as well as view and save measurement results. Also included is a 3D-printed Rotate & Push module
to test the common functions of angle measurement and push button with a single device.
The EVM is intended to provide basic functional evaluation of the devices. The layout is not intended to be a
model for the target circuit, nor is the model laid out for electromagnetic compatibility (EMC) testing. The EVM is
intended to interface with the TI-SCB, but can be used as a standalone device if desired.
2.1 Features
• On-board 16 bit Analog to Digital converter
• Differential sine and cosine analog outputs
• 3D-printed Rotate & Push module
• Easy USB measurements using the TI - Sensor Control Board (TI-SCB)

3.2.1.2 Firmware
The GUI can load firmware onto the TI-SCB as described in Section 3.2.1. Firmware updates are pushed
through the GUI (requires driver installation). Downloaded offline GUIs can check for GUI/Firmware updates
depending on the version.
3.2.1.2.1 Firmware Debug
If the firmware becomes corrupted or requires manual reinstallation for any reason, follow these steps to restore
the firmware. This is demonstrated in the TMAG5170 EVM Quick Start Video:
1. Configure the MCU on the TI-SCB Controller to Device Firmware Update (DFU) Mode.
a. The MCU entering DFU mode is possible. If so, then the GUI sends a notification and tries to update the
firmware to the latest version after the GUI is connected to the PC.
b. DFU mode can be entered manually through one of the following methods while the TI-SCB Controller is
powered on:
• Through software:
– Send the command 'bsl' on the TI-SCB's USB Serial (COM) port.
• Though the hardware:
– Make sure TI-SCB is connected to the PC through a USB
– Short the two test points near PK1 and PK2 of the header pins (see Test Points Used to Enter
DFU Mode Manually) with a pair of tweezers (or wire) while pressing the RESET button.
Figure 3-7. Test Points Used to Enter DFU Mode Manually
c. LEDs D1 and D2 are off if successful.
2. With the MCU in DFU mode, upload the firmware through the GUI:
• Open the File menu and select Program Device.
• The firmware update initiates.
• After the GUI re-initializes, the TI-SCB automatically connects.
If the firmware programming was unsuccessful, then TI recommends to repeat the above steps with a different
USB port connection on the machine.
3.2.1.3 GUI Setup and Usage
Access the GUI from the following link in either a Firefox or Google Chrome browser:

3.2.1.3.1 Initial Setup
To set up the GUI the first time, follow these steps:
1. Make sure that the above mentioned driver was installed successfully to verify that everything works properly
and that the GUI can update the EVM firmware, if necessary.
2. With the EVM/TI-SCB Controller unit plugged to the PC, go to the GUI link: https://dev.ti.com/gallery/search/
TMAG6180-6181.
3. To launch the GUI from the web browser, click the GUI Composer application to open the GUI Composer
window (see GUI Composer Application Window).
Figure 3-8. GUI Composer Application Window
a. For first-time GUI Composer setup, follow the prompts to download the TI Cloud Agent and browser
extension (see TI Cloud Agent). These prompts appear after you close the README.md dialog.
Figure 3-9. TI Cloud Agent
4. Optionally, click the icon in the GUI Composer window to download the GUI for offline use (see GUI
Composer Application Window).
3.2.1.3.2 GUI Operation
To operate the GUI, follow these steps:
1. Connect the EVM to TI-SCB and mount the Roate & Push Module.

2. Connect to and launch the GUI as described in Initial Setup.
3. With the EVM connected to the GUI, close the README.md file page. The text near the bottom-left hand
corner of the GUI reads Hardware Connected (see Hardware Connected Indicator).
Figure 3-11. Hardware Connected Indicator
a. If Hardware Connected does not show in the bottom-left hand corner of the GUI, check different
hardware COM ports under Options → Serial Port (see Change Serial Port).
Figure 3-12. Change Serial Port
b. If the hardware still does not connect, make sure you are using the correct GUI/EVM combination.
4. Click on the Plots icon to setup the EVM for measurements.

STANDARD TERMS FOR EVALUATION MODULES
1. Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or
documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance
with the terms set forth herein. User's acceptance of the EVM is expressly subject to the following terms.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.
2Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License
Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)
business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.
2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit
User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty
period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or
replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be
warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
WARNING
Evaluation Kits are intended solely for use by technically qualified,
professional electronics experts who are familiar with the dangers
and application risks associated with handling electrical mechanical
components, systems, and subsystems.
User shall operate the Evaluation Kit within TI’s recommended
guidelines and any applicable legal or environmental requirements
as well as reasonable and customary safeguards. Failure to set up
and/or operate the Evaluation Kit within TI’s recommended
guidelines may result in personal injury or death or property
damage. Proper set up entails following TI’s instructions for
electrical ratings of interface circuits such as input, output and
electrical loads.
NOTE:
EXPOSURE TO ELECTROSTATIC DISCHARGE (ESD) MAY CAUSE DEGREDATION OR FAILURE OF THE EVALUATION
KIT; TI RECOMMENDS STORAGE OF THE EVALUATION KIT IN A PROTECTIVE ESD BAG.

3.1 United States
3.1.1 Notice applicable to EVMs not FCC-Approved:
FCC NOTICE: This kit is designed to allow product developers to evaluate electronic components, circuitry, or software
associated with the kit to determine whether to incorporate such items in a finished product and software developers to write
software applications for use with the end product. This kit is not a finished product and when assembled may not be resold or
otherwise marketed unless all required FCC equipment authorizations are first obtained. Operation is subject to the condition
that this product not cause harmful interference to licensed radio stations and that this product accept harmful interference.
Unless the assembled kit is designed to operate under part 15, part 18 or part 95 of this chapter, the operator of the kit must
operate under the authority of an FCC license holder or must secure an experimental authorization under part 5 of this chapter.
3.1.2 For EVMs annotated as FCC – FEDERAL COMMUNICATIONS COMMISSION Part 15 Compliant:
CAUTION
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to
operate the equipment.
FCC Interference Statement for Class A EVM devices

the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
FCC Interference Statement for Class B EVM devices
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
