TDA4VM-Q1: The differences between MCU_MCSPI and MCSPI in TDA4

The differences between MCU_MCSPI and MCSPI in TDA4.

We need to connect 3 DSI3 Controller ICs(ELMOS E52142A) to the SPI of TDA4, the DSI3 interfaces are used for USS(Ultrasonic Sensor).

MCU_MCSPI or MCSPI(Main domain)? which is better?

Is it better to connect 3 E52142A to 3 SPI or 1 SPI with 3 CS(chip select)?

Thanks.

Hi Hui Liu,

From the module point of view, McSPI in Main domain and MCU domain are exactly same. Main domain can be switched off and it can run only on mcu only mode. So it depends on your requirement and pins availability..
