|"Hello all, |
| |
|We are having a hard time finding a suitable microcontroller for our new |

Hello,

A suitable but excessive device would be one designed for use in
space, e.g. a field programmable gate array for space from Aeroflex (
HTTP://AMS.Aeroflex.com/ProductFiles/DataSheets/FPGA/RadHardEclipseFPGA.pdf
at -55 degrees Celsius compatible with a synthesized 8051 clone which
can address gigabytes of memory (
WWW.SiliconLaude.com
). I have found Aeroflex and Silicon Laude to be pleasantly flexible,
in contrast in my experience, my point of contact in Honeywell did not
make enough of an effort to export components for extreme conditions.

If you speak to Aeroflex and Silicon Laude, they may be able to
suggest some division other than its astronautical division which
might make devices which are suitably cheap for you but still adequate
for a low temperature.
