CC2755R10: Which GPIOs are for PTA pins on CC2755R10?

Part Number: CC2755R10

Tool/software:

Hi TI expert,

My customer design needs the PTA (coexistence) pins with WiFi chip, but we can't find any PTA pin definition in CC2755 datasheet, "CC2755x10 SimpleLink Family of 2.4GHz High Performance Wireless MCUs datasheet". Could TI tell us if CC2755 supports PTA or not? If yes, which are these pins?

BR, Jesse.

Hi Jesse,

It has been explained to me that the CC2755R10 will begin to support the WiFi Coexistence feature in the next F3 SDK release, planned for the end of April, and that PTA pins can be mapped to any LRF Digital pin (DIO17-22, DIO27-28).

Regards,
Ryan

Hi Ryan,

Just to double confirm there is not typo of "any LRF Digital pin (DIO17-22, 27-27)". So from 27-27, is that right?

Hi Ryan,

Do you mean below pins ? Thank you.

The original message meant to say DIO27-28, I've corrected that now.

Hi Jerry,

Yes those are the physical pin numbers for the QFN40 package which correlate to the DIO pins I mentioned.
