True, but where do you buy them?  Digikey and Mouser only give you a -40C option on the search windows and even Atmel's "Check Inventory" function returns "no parts were found" (at least on the few I've checked in the past).

I'm sure if you want to buy 100K of them, Atmel would accommodate you.

  Jim -

  There are a number of AVRs that are "automotive grade". You will find them
  in Atmel's miserable web site in the 8-bit mcu section. THese have
  extended temperature specs, if I recall correctly.

  For example:

  http://www.atmel.com/dyn/products/devices.asp?category_id=163&family_id=607&subfamily_id=1723&source=left_nav

  lists the Mega88/168 Automotive with a temp range of -55C to +150C.
