Sorry!!

I did confuse the LQFP package with the QFN package. I've seen the
LPC2106 in a QFN-48 but mo information about availability of the
64-pin device in QFN-64

Bob

btw. I did not even know that a QFN package is on the roadmap. Were
did you get the information about such a package for the LPC2xxx?

I didn't. Now that I have looked at it harder, I realize that I have
not seen any note on the larger part being available in a smaller
package. At least I can't say for sure I have seen anything. Philips
has done a pretty poor job of documenting where they are going with
these parts and I have found tons of discrepancies between the web
site, the data sheets and the info I have gotten directly from the
sales reps.

Even the latest User Manual for the LPC2114/2124/2212/2214 lists the
memory sizes differently on different pages.

The info I got from my sales rep shows, LPC2114FBD64, LPC2114FHN64,
LPC2124FBD64, LPC2124FHN64 part numbers. The same package designators
are shown for the LPC22 parts. I have also seen some web pages that
show a 64QFN part number. This info also shows LPC2194HBD64,
LPC2194HHN48, LPC2290HBD144 and LPC2294HBD144 part numbers which are
full automotive temps with CAN and ADC, the last two having an
external bus. The 2290 has no internal Flash.

But I think I can let this go now. Since the 2214 does not come in a
small package, I can't fit it on my board. I'll stick with the OKI
part in the 11mm BGA.
