I took a look at the data sheet and it appears that this part also has
a separate power supply for the RTC from the rest of the chip.  This
is *very* interesting.  The data sheet does not have a value or even a
label for the Ibat current.  Is there any sort of a number for this? 
Will it be comparable to the RTC chips of <2 uA?  

Also, I have seen MCUs (not Philips) that are rated for industrial
temps, but can not be stored above 85C due to the Flash losing its
data.  Is this a consideration for the LPC213x?  Or can it be stored
with power removed up to the spec value of 125C without speeding the
loss of data in flash?  

Finally, where can I get price and delivery on these parts?  They
don't seem to be available anywhere yet.  Is this a viable part for a
new design going to board layout in the next month or so?
