HI Sreenivasa

All of the above links seems to be for C2K devices.

Please give me a draft doc to share the information for FSI design to customer quickly, and add it to the document SPRACU5C "AM6442, AM6422, AM6412 and AM2434 Schematic Design and Review Checklist" (link).

Hello Tsurumoto,

Thank you for the note.

As i understand the IP is the same and it should be Ok for customer to use C2K information.

We do not have any guidelines added specific to FSI in the checklist and the data sheet reference has been added above.

It is not user-friendly. Please add at least a link to C2K's FSI design guide to the document SPRACU5C "AM6442, AM6422, AM6412 and AM2434 Schematic Design and Review Checklist" (link)

Hello Tsurumoto,

Below is the only document that i have not referenced. Please refer below

FSI References

Other TI documents relevant to the FSI Adapter Board are described in Table 10.

Table 10. FSI Reference Documents

I am not sure if there are any additional documents for reference.

Hello Tsurumoto,

Please refer below FAQ.

Hi Sreenivasa

The link you sent did not include any circuit design precautions, such as "a 22-Ω resistor is required closest to the processor pin" or "a pull-down resistor is required", as listed in the checklist above.
Do you mean that there are no such precautions for FSI?
Also, is there any precautions for pattern design such as "guarding with GND"?

Customer are doing the board design, therefore they need the informatin such like "schematic checklist" for FSI.

Hello Tsurumoto,

Thank you.

I would recommend reviewing the below TI design

www.ti.com/.../TIDM-02006

Let me check internally if there are any guidelines.

This is a c2000 peripheral, i will check if there are any documents available.

Sreenivasa

HI

Did you get the feedback?

Hello Tsurumoto,

Thank you.

I could not find any additional information to share.
