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,

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

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

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?
Andy
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...).

Well I get lots of hits for microcontrollers for "automotive" applications, but most of these don't seem to mean for "automotive"
*temperatures*!
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,

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.
