Talking about loneliness and highly resilient technology to be used in deed space, I can't resist to copy here this small statement from the above Peregrine Semiconductor Corporation publication:

"The farthest man-made object from the earth,
the Voyager 1 spacecraft, has an RCA-built SOS
microprocessor aboard it. It was launched in 1977
and left our solar system in 2003. As of January
2006 it was 14 billion kilometers from earth and still
functioning
"

Note that that statement is in error.

Members of the Yahoo COSMAC ELF group have verified that ONLY the Galileo spacecraft used the 1802.
Neither Pioneer, Viking, Voyager, nor any other spacecraft, used the 1802.
(the Space Shuttle MIGHT have used one in one of its systems)
There are a few Earth-orbiting satellites that used the 1802. (OSCAR?, ...)

If you read the above statement carefully, you will see that there is no mention to the RCA 1802 processor. The article's author just mention "RCA-built SOS
microprocessor " without going to deep details.

We cannot imply from his words that he claimed that a 1802 was used in the Voyager.

Additionally, the article author is an accredited person working on SOS technology since the NOSC era, so I have no reason to doubt his words.
Here is the information extracted from that article::
George Imthurn is a Device Engineer for Peregrine Semiconductor
Corporation, a manufacturer of UltraCMOS-based RFICs. During
his tenure at Peregrine he has contributed to the basic understanding
of SOS and worked on improving the radiation hardness of the
UltraCMOS process. Before joining Peregrine he worked on SOS at
the Naval Ocean Systems Center. George received his BS at Pacific
Union College and his MSEE at San Diego State University. His
thesis work was on guided wave optics
