Number of SPI on MKW01Z128?

[josegorjon]

We wish to use the MKW01Z128 to a new electronic system where it has to read an accelerometer/gyroscope (I2C) and a sigma delta digital converter (SPI).

After having a look on the datasheet, I have a doubt about the number of SPI port that the MKW01Z128 has. Has it one internal dedicated to the RF, and one external, or just only one?

Hi Jose, I hope you're doing well!

The KW01 contains two SPI modules, however, only one of them is available to the user, as the other one is dedicated to the transceiver chip, and it's used for configuration and data transmission of this chip, and cannot be used for other purposes.

For more information about both modules, please check the KW01's Datasheet, sections 5.1 and 5.2.

Please let me know if you have any other questions.

Best regards,

Sebastian
