    CYW4343W: SPI instead SDIO for WiFi

    ClFu_4740231

      Hello

       

      For a customer project we would like to use the Murata module LBEE5KL1DX-883 with the integrated CYW4343W Bluetooth-WiFi combo chip. As host controller we use an STM32L4S7ZI. Since we need to use the SDIO interface from the micrcontroller for something else, we would like to interface the CYW4343W via SPI.

      Can you confirm, that it is possible to control the WiFi part via SPI by pulling "SDIO_DATA_2" pin low?

       

      Thanks for your help.
