Subject: Standalone Evaluation Software / GUI for MC33774A AFE (RD33774CNC3EVB)

[sanket_dudhmande]

I am working with the RD33774CNC3EVB (MC33774A-based CMU) and the RD-K358BMU evaluation board.

I would like to evaluate and validate the MC33774A AFE independently, without integrating the complete BMS system. My goal is to verify features such as:

- Cell voltage measurements

- Temperature measurements

- Diagnostics and fault reporting

- Passive cell balancing

- Register configuration

- Communication between the BMU and AFE

I have the following questions:

1. Does NXP provide a standalone evaluation GUI or PC software for the MC33774A?

2. Is there a FreeMASTER project, demonstration GUI, or any other graphical tool that can be used to monitor and configure the MC33774A through the BMU?

3. Is there a reference application or example firmware that enables evaluation of the MC33774A with minimal software development?

4. Are there any applications describing the recommended setup for evaluating the MC33774A using only the BMU and CMU evaluation boards?

My objective is to perform functional validation of the AFE before integrating it into a complete BMS system.

Thank you for your support.

Can we use RD33774CNT3EVB(which is TPL based) for standalone testing as the mentioned part number is not available with us but RD3374CNT3EVB id available along with the required setup

Dear Sanket,

1. Does NXP provide a standalone evaluation GUI or PC software for the MC33774A?

[A] Yes, there is an EvalGUI 7 for the MC33774A. Specifically to be used with RD33774ADSTEVB. The GUI is intended to be used with SPI interface for communication between MCU and SPI to TPL transceiver and then via TPL to the MC33774A. Please refer to the UM11816.

If you are asking if there is a GUI specifically for the RD33774CNC3EVB with populated MC33665A TPL to CAN transceiver for the communication with MCU via CAN interface, unfortunately, there isn't any. 

2. Is there a FreeMASTER project, demonstration GUI, or any other graphical tool that can be used to monitor and configure the MC33774A through the BMU?

[A] For the BMU and CMU boards you mentioned we have a whole software bundle. However you need an S32DS IDE.

Please refer to this link. Included are Demo projects for the FreeMASTER.

3. Is there a reference application or example firmware that enables evaluation of the MC33774A with minimal software development?

[A] See above what software is available for the EVBs you have. However, the two boards are not sufficient. You need your own battery pack, with minimally 4 Cells for each MC33774A, or we have BATT-18EMULATOR. Emulating 18 Cells for each MC33774A populated on the RD33774CNC3EVB. 

Please refer to the UM11943.

4. Are there any applications describing the recommended setup for evaluating the MC33774A using only the BMU and CMU evaluation boards?

[A] Yes there is. However as mentioned above you need either a battery pack or the battery emulator. Please refer to the UM11943 and to this link.
