The Fairchild F9450 is a high-performance 16-bit 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[edit]

The Fairchild F9450[1] 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.

Support chips[edit]

F9450 CPU (Central Processing Unit)
F9451 MMU (Memory Management Unit)
F9452 BPU (Block Protection Unit)

Simulation/Compilers[edit]

XGC Technology offers a C and C++ compiler and simulator for the F9450. The Compiler meets

the requirements of the European Space Agency for 16-bit spacecraft applications.[2][3]
