Dear NXP forum,
I bought some LPC54S018J 4M ET180 micro controllers and already found out the hard way that LPC54S018J ET180 (without 4M) have an different pin-out. Now i am trying to fix this.
So i was trying to find the right footprint for the LPC54S018J4MET180(with 4M), but i only found footprints at "ultralibrarian.com" for LPC54S018J4MET180E.
In fact, I already made a big mistake with the 4M label and i am trying to learn from my mistakes. Now I am really cautious of every single character in the name.
I already read the data sheet and they are explaining a lot of the naming convention, but I did not find the E explained anywhere.
So my question:
What does the E mean and does it influence the pin-out?
Here is an picture of my LPC54S018J4MET180, it does not have the E.

Thank you for the help!
greetings Paul
