TLx5012B 2go Evaluation Kit
General description
1 General description
The TLx5012B 2go is a budget-priced evaluation kit to evaluate several derivatives of the Infineon
TLx5012B GMR angle sensor:
• TLx5012B E1000: industrial version with IIF interface
• TLx5012B E1000: automotive version with IIF interface
• TLx5012B E5000: automotive version with PWM interface
• TLx5012B E9000: automotive version with SPC interface
All derivatives provide an additional SSC interface used for both reading the angle value and setting the
internal registers of the sensor.
A mechanical rotation knob may be ordered independently from the hardware evaluation kit, providing
magnetic stimulus to the sensor.
The evaluation kit includes a GUI software application that can be downloaded from the evaluation kit
product page.

General description
1.2 Hardware description
The evaluation kit hardware is built around the XMC1100 Infineon target microcontroller (4), ARM M0 based.
In addition, the hardware includes an on-board debugger microcontroller (5) implemented with the Infineon
XMC4200 running a SEGGER Jlink debugger.
Figure 2 TLx5012B 2go evaluation hardware
The sensor supply is ensured by a TLE4250-2G tracker (3) dynamically enabled / disabled by the target
microcontroller.
Two MOS transistors (2) - one PMOS and one NMOS - are being used for enabling a pull-up resistor (2.2 kΩ) and
for pulling down the line for the SPC pulse generation. Both transistors are controlled by the XMC1100 target.
The sensor (1) is placed on a break-apart region of the PCB so it can be removed and placed in a system.
For the connection to the PC a micro-USB (6) to USB cable is required (not provided with the package).

Software installation - step 3
It is recommended is to use the default installation path, but you can select a different installation folder.
You can also select whether a desktop icon is to be generated or not.
The hardware device will only operate on a computer that has the Segger Jlink driver installed. The installer
checks this, and if no driver is found, you can select to install Segger Jlink driver as well.
The software GUI is built in .NET environment 4.5. A check is being done for compatibility and you can select
to install (if not already installed) the .NET framework 4.7 (web installer – requires connection to internet).
