LPC2103FBD48 packaging marking meaning

[SSFEL]

Hi I was wondering if you could explain the meaning behind the packaging marking of the LPC2103FBD48?

The one I need to identify shows this;

LPC2103F

18 02 ZSD

1829B

Thanks

Hi 

FBD48 means LQFP48 package

the second line is factory tracking information. not for external customer.

the third line is manufacture date and version. see below.

Have a nice day,
