The '''Fairchild F9450''' is a high-performance 16-bit [[bipolar process|bipolar]] [[microprocessor]] developed by [[Fairchild]] in 1985. The F9450, which implements the [[MIL-STD-1750A]] standard, was designed for both commercial and military applications. Fairchild also manufactured a radiation-hard version which has been deployed in various spacecrafts.

== Overview ==
 
−
The Fairchild F9450 was one of the first chips to implement the [[MIL-STD-1750A]] specification. The chip features real-time processing abilities, two programmable timers, interrupt and fault handler support. The chip has built-in support for both single and extended (32 and 48-bit) floating point operations without the need for a co-processor extension as specified by the standard - unlike many other chips which implement the MIL-STD-1750A standard.
