High temperature floating point digital signal controller

McZ writes: I have used the SM320F28335-HT microcontroller in several projects including military applications. With the floating point it is blinding fast. The standard temperature comes in a QFP and the high temp version comes in a Ceramic Pin Grid Array which is more friendly than the BGA’s. The TI compiler/IDE is cheap by high end standards and they have a vast open source library. Price for the high temperature version is $325.00 USD !!!!! Standard temperature version <$20.00 USD.
