Hi John,
the LPC2294 and the LPC2194, which have the same block diagram except
the 2294 has an external bus, are both specified for -40/125C without
speed penalty, still full 60 MHz from Flash.

Well I get lots of hits for microcontrollers for "automotive"
applications, but most of these don't seem to mean for "automotive"
*temperatures*!
> Philips have Automotive rated ARMs
I do see some 105`C parts that I missed before: LPC2194 and
LPC2294. On reflection I think I need 115`C or 125`C (if such exist),
since there will be a temperature differential between the inside and
outside of the product :(

Thanks, I will look into Freescale.

Not well defined at present - it depends how I partition the software
and hardware, on- and off- chip functions. (Doesn't it always...).

Freescale (was motorola) do a lot of their microcontrollers in
automotive spec (-40 to 125).
What I/O requirements do you have for the project?

Feescale 9S12X MC9S12XA512 with suffix VPV have -40..+105C
and MPV -40...+125C working temperature range.

Zilog have a lot of 105'C rated devices, and if you google for
Automotive "ARM microcontroller" you get many hits...
Philips have Automotive rated ARMs

Anything rated as "automotive" will do the job.. usually 125 degrees Celsius

Hello embedded people!
We have a new project that may require operation at perhaps
105`C. This is well above what I am used to working with, so I have
not paid much attention to "extended" temperature range parts. Now I
need to find some!
I am looking for suggestions for microcontrollers. Would prefer
something modern and C (gcc) friendly, like e.g. the LPC2100 series I
was going to use...
Any ideas?
Thanks,
