I have found that we seem to have different codes on some of the W5300 chips we have, and am trying to find out what they mean and if there are different chip silicon / ‘firmware’ revisions and what the changes are.
e.g. W5300 PN0T0-010 1719 (I assume that is 19w of 2017)
and W5300 PRQW4-010 1916
In the photo’s on your website and user manual there are examples showing
Part of this is to try and identify why there are differences in performance and stability with a product we have designed and is currently under test/evaluation where the rest of the board and firmware is the same but we seem to have differences in the silicon.
