>> Are there any other microcontrollers/mpus [with MIPS architecture]

LOTS of MPUs/SoCs.  Cavium, PMC-Sierra, and Broadcom, haven't been =20
mentioned yet.
Many modern cisco routers have high-end MIPS processors, for example. =20
Significant numbers of relatively small fabless SoC vendors trying to =20
put together the ideal combination of bits to attract cisco and =20
similar companies. They tend to be targeted toward high-end embedded =20
systems (external RAM) where they're not so obvious (while ARM has =20
been aimed toward lower-end systems like cell phones.)  See for =20
instance the Cavium Octeon family, featuring up to 32 cores at 1.5GHz.
(It's not like MIPS didn't TRY to get the low end as well; I have an =20
old PDA I won at some "MIPS Inside" trade-show.  They just lost out...)

Microchip is the only vendor I know of with a MIPS-based =20
microcontroller.
