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. Application Note 3 Rev. 1.0 2018-09-27 TLx5012B 2go Evaluation Kit General description 1.1 Assembly variants The TLx5012B 2go kit comes in 4 assembly variants while the support PCB is always the same. The sensor used may be one of 4 predefined: TLI5012b E1000, TLE5012b E1000, TLE5012b E5000 and TLE5012b E9000. The TLE5012b E3005 is not targeted by this evaluation kit. The content of the evaluation kit is shown on the back of the delivery box with a check mark in one of the four boxes. Figure 1 Assembly variants The type of sensor can also be identified by checking the markings on the sensor package: Table 1 Markings Product type Marking Ordering Code Package TLE5012B E1000 012B1000 SP001166960 PG-DSO-8 TLE5012B E3005 012B3005 SP001166964 PG-DSO-8 TLE5012B E5000 012B5000 SP001166968 PG-DSO-8 TLE5012B E5020 012B5020 SP001166972 PG-DSO-8 TLE5012B E9000 012B9000 SP001166998 PG-DSO-8 Application Note 4 Rev. 1.0 2018-09-27 TLx5012B 2go Evaluation Kit 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).
