Hi,

SAME53 chips in 64-pins packages, of Revision A, do not have functional Ethernet module (pin GRXDV not available).

It should be fixed on Revision D chips.

Problem is - where to get them ?

 

I have sent emails to tech.support of main suppliers/distributors with following result:

- some of them admitted they do not have such a detailed information about chips they sell, so they don't know Revision

- some others didn't answer for >3 days, so I am skeptic they ever will

 

Could please anybody confirm recently bought any SAME53J19A.. or SAME53J20A.. chips of Revision D, i.e. Device Signatures 0x61830305 or 0x61830304 ?

Please state which distributor & order code.

You probably will need to consult directly with Microchip sales.

Regrettably, Microchip Direct is one of the companies not answering my email.

Microchip Direct is different than Microchip Sales.

 

Look up your geography here. https://www.microchip.com/salesd... They will give you a phone number to your local Microchip office, and/or a sales representative with whom Microchip has contracted to cover that geographic area.
