TMS320F28388D: FSI "Multi-Slave Configurations" example

Part Number: TMS320F28388D


Hello everyone,

I am planning to use the FSI to connect multiple TMS320F28388D with each other.

In TIs documentation (SPRACM3D) there is an example using a daisy chain explained.

In the TRM of the TMS (32.3.10 Multi-Slave Configurations) another approach is explained, does TI have an example using the described alternative instead?

Thanks and regards,

Marcel Kummer.

    Hi Marcel,

    We recommend using the implementations discussed in the SPRACM3 App Note. That includes the daisy-chain or star connection example, which both have accompanying SW examples.

    We don't have an example for the TDM_IN implementation and don't really recommend it due to signal degradation concerns (because FSI packets are not re-transmitted by the device in the implementation). Let me know if you have any other questions.

    Best,
