As you no doubt already know, some people have used standard
(non-rad-hardened) CPUs in satellite applications.

For instance Clementine used a MIPS R3081 for its sensor interface
processor. (See table 9 in

)

Of course lunar orbit is likely a lower radiation environment than
low-earth orbit, and there were two lower level processors for basic
control which _were_ rad-hardened.
