TSB82AF15-EP: Use of GRST

David Roberts

Part Number: TSB82AF15-EP

I am designing with the TSB82AF15-EP I have a question regarding the use of the GRST input.

I see in some applications, GRST is left unconnected (has internal pull up).

Will the device work well with just PERST being asserted?

Thanks

Hi DR,

The GRST is functionally the same as the internally generated power on reset. I don't see any required timing around GRST documented.

Let me check with design there is no requirement for GRST.

Yes, it can be left floating. Customers often like to control it just in case a chip reset is needed.
