Hi all,
I am designing a BMS for a one-off use case with the S32K148 before moving to the S32K3. I want to use the S32K1 MBDT so looking at the MC33664 for the TPL control and MC33771C's for the cell monitor boards.
I want to have a loopback system running with 2 x MC33664 so that it protects for a single disconnect/failure in the TPL loop harness.For the loopback it looks like I need all 3 SPI busses for this, is that correct? If so, because this changes the SPI the 48b transfer size, will I be able to share this SPI bus with the UJA1132 SBC? I want to use the UJA as my power supply for the uC stepping down from a 12V supply voltage. Looking at the UJA examples it always uses 8b SPI transfer size. I would want to put this on the common TX bus for the 2 TPL ports to keep both TPL RX lines on their own.
Is this possible? Or is there a workaround for this if not?
Thanks in advance!
