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.

Hello,

Unfortunately, the SPI interface is not supported.

You can refer this thread for your reference: https://community.cypress.com/message/191514#191514

Thanks

Hi AditiB_81

Thanks for your answer.

That's a pity it is no longer supported. I think you should update the information on the homepage https://www.cypress.com/products/wi-fi-bluetooth-combos. Here the gSPI interface is still listed for WiFi for CYW4343W.
