Hi,

I am using CY8C6347BZI-BLD54 and I would like to double my i2s signals (defaulted on port 5), on another port, for example port 8. Is it possible to route them internally? 

 

I want to do this since port 5 will have 3.3V domain, while port 8 will have 1.8V domain, that is the voltage that the i2s device on the other hand is using. If i can double my i2s signals on port 8 IOs, then I don't need a level shifter between the psoc and the i2s device.

 

thanks!

 

best regards,

 

A.

You can't route the I2S pins directly to another port. However, if you have enough pins to spare, you could implement a level shifter within the PSoC. It would require 3x time more pins. The thinking is:

1) Connect the I2S pins from Port5 to other port at 3.3V externally.

2) Internally, establish a direct connection between this other port pins and the Port 8 pins.

thank you for the answer.

Would it be possible to route them internally using UDB? or completely replace the i2s peripheral and use a udb -based one?
