TMS320F28388D: Is there FSI communication reference schematic?

Hi Dave,

Some documentation references that I think would be useful for you about FSI:

• FSI Multi-device App Note
• TMDSFSIADAPEVM Hardware Reference User's Guide
• The Essential Guide for Developing With C2000Real­ Time Microcontrollers
  
  • See section 5.3 Distributed Real-Time Control Across an Isolation Boundary

When I wanna use FSI communication between two of TMS320F28388D,  Do I have to use Isolator IC?

No, digital isolators are not requires for FSI communications. You can directly connect FSI TX signals to FSI RX signals of the communicating devices. Differential ICs would be needed for communicating over longer distances and/or to greatly improve noise immunity of the physical link.

Which do i use Pin?

(For exmaple, FSIRXA_CLK, FSIRXA_D0, FSIRXA_D1, FSITXA_CLK, FSITXA_D0, FSITXA_D1) is it enough?

Ground connections are needed as well. Also, D1 data signals are optional, but increase total throughput.

Best,

Kevin
