The MCSXTE2BK142 Hardware System

1. The 12-36 V VBAT input connects to a reverse battery protection circuit and provides VIN, which is then converted by the DC-DC converter to 7 V VPRE and 5 V VDD through 2 LDO regulators.
2. The VIN directly connects to the 3-phase MOSFET high-side power stage and GD3000 pre-driver for motor control.
3. The S32K142 MCU and the TJA1043 CAN transceiver use the VDD. For debug purposes, an SWD debug port is reserved for program download and debug. A TTL UART communication interface is provided for FreeMASTER/MCAT communication. A 5-pin connector is routed with TRIGMUX signal for FOC trigger monitor. Additionally, there are hall sensor and encoder interfaces for sensor-based FOC motor control, and signal conditioning and PGA circuits to sample the 3-phase current and back-electromotive force for sensorless FOC.
4. One CAN bus and one LIN bus, along with a high-voltage PWM input interface, are designed for external connectivity extension, supporting user motor control (rotation direction, speed) commands and motor diagnostic information feedback.

• Supports 24 V power supply system with up to 800 W automotive BLDC/PMSM motor control system.
• Able to drive multiple types of automotive motors and tune those motors directly.
• PMSM FOC based on NXP S32K142+GD3000+CAN PHY+LIN PHY.
• Dual shunt and triple shunt current sample solutions are implemented.
• Supports multiple diagnostics and protection covering UV, OV, OT, OC, short, and stall detection.
• Supports speed/control commands from LIN/CAN/PWM.
• Out-of-box motor control and tuning via FreeMASTER MCAT.
• Supports sensorless FOC PMSM/BLDC motor control.
• Supports hall/encoder sensor based FOC PMSM/BLDC motor control.
• Implements advanced motor control algorithms like field weakening (FW) and stall detection.
• Provides S32DS IDE project and makefile project to support multi-toolchain (GHS, IAR, and GCC) and multi-debugger (Lauterbach, U-Multilink, and J-LINK).

Step-by-Step Instructions

All documents (Fact Sheet, Quick Start Guide, Software User Manual, Hardware User Manual) for the MCSXTE2BK142 are available on: nxp.com/MCSXTE2BK142. Before starting, download and install the following software:

• FreeMASTER 2.5 or newer

Step-by-Step Instructions Continued

1. Download Software

   Download installation software and documentation at nxp.com/MCSXTE2BK142.

2. Connect Your PMSM Motor

   Connect your PMSM motor with the MCSXTE2BK142 via J11. Connect your hall sensor or encoder with J5 and J6 if your motor has them and you want to assess the sensor FOC motor control.

3. Connect Debugger and Power on the Board

   Connect a debugger (PEMicro U-Multilink/J-LINK) with the board via J4/J3. Provide 12V/24V DC power supply to the board; then the D13 green LED will be on.

4. Import and Build the Demo

   Import the selected demo project from the NXP\MC_DevKits\MCSXTE2BK142\sw folder into S32DS for Arm^® IDE, clean, and build the project. You can also use other toolchains, such as IAR or GHS, to compile the project via makefile. For details, please refer to the software user guide.

5. Download and Debug the Project

   Launch the debug target in the debug configuration according to the actual debugger you are using. Download the compiled result into the board and enjoy the debug.

6. Tuning your Motor via MCAT

   Using a USB-to-UART converter, connect the board with your laptop via J2. Open the MCAT project S32K_PMSM_Sensorless.pmp under the FreeMASTER_control sub-folder with FreeMASTER. Connect to start tuning your motor.
