Query regarding cascading the boards

[Varun_V_Sharma]

We are trying to have an evaluation board which can manage 20 LiFePO cells in series and would like to know whether MPC5775E-EVB can be cascaded to serve this purpose. If yes, kindly indicate the steps to be followed.

Thanks and regards

Hello,

Have a look at the dev kit board with MPC5775E:

https://www.nxp.com/design/designs/mpc5775b-bms-and-vcu-reference-design:RDVCU5775EVM

The system mainly consists of a master board and several slave boards connected in series with a daisy-chain with TPL.

To MC33771 - you can connect up to 14 cells.

You can also consider a design with S32K3xx which is more advanced microcontroller:
