Not just the Japanese, see National Semiconductor's
COP series and Cygnal's 11-pin 8051.

Eg. COP8SAA7 4.5 x 5.5mm 28 pins
(16-pin SOIC version is about 75 cents/1k)
Or a 44 pin 6mm x 6mm..

Or.. C8051F301 3mm x 3mm 11 pins
(has 8K of flash on chip, an internal oscillator that
is accurate enough for serial comms, runs at 25MIPS)
Digikey wants about $4-5 for these in 100's

The problem with the 3-pin package is figuring out how to multiplex power
and ground. ;-)
