LPC1857JET256 Chip Markings Batch Information

[jean-riegardtva]

Good day

I really struggling to get a hold of processors for my project. I am working with the NXP LPC 1857JET256. I received some units from an uncertified source and now I am trying to verify them. Can any one point me to somewhere where I can read up on what the additional markings mean on the chip. I'm hoping for manufacturing dates and batch numbers. The Chip reads the following:

NXP

LPC1857JET256

P4GS15.00     Q1

ESD16080A

Thanks
