Lpc2000

We have internally qualified the CAN type devices (all that include a
"9") for operation up to 125C. 

The problems related to high temp are reduced speed and high stress /
shorter life of the devices. Different devices manufactured in the
same process will show very similar temperature behaviour. All LPC2000
devices available today, except the flashless versions, are
manufactured in the same flash process.

We can run our LPC2000 devices at 60 MHz with an ambient temperature
of 125C, nevertheless, there is no qualified test equipment for 150C
or higher that we would have available. 

As previously mentioned by other members, provided a few hours life
cycle combined with reduced speed, let's say 40-50 MHz, and no
reprogramming while hot, I would expect the devices to work properly.
 
Unfortunately Philips will not be able to guarantee operation under
these conditions. It is up to test runs at your end, sorry!

Hope this helps, Robert
