This CPU was one of the first 16-bit microprocessors, and the first to be designed and manufactured in Europe.
The CPU has the ability to operate over a wide temperature range of -55C to +125C and is resistant to the effects of radiation.
Bipolar technology was chosen for it's radiation hardness and it has been shown that the F100-L is almost totally latch-up resistant even after significant doses of radiation.
It is listed by the MOD as being "Nuclear Hard".
