Lpc2000

Hi Bob,

Thanks very much for the reply, Bob.  The information is very helpful.

Even though the current product, as spec'ed, mentions something like 4
updates max over the life of the product, it never occurred to me that
*if* we were go to 8...10... 15 updates (you know how these things
go), the reliability might not be as high.

Regarding the 2102, I'll "run it up the flagpole" so to speak... as
you can imagine, I always get push-back when I ask for anything!  In
fact I initially spec'ed the '03 (at least during design/development),
saying we can always drop down to the '01 or '02 for production if
everything will fit.... and man-o-man, you should have heard the wailing!

Have a nice weekend & thanks again for the help.

Dan
