Looks like this is a great chip to interfacing with Stamp. The chip includes 6 preprogrammed configurations (RC servo control, data acquisition, motor cotrol, LCD...), supports I2C and serial interface. (www.web4robot.com)
Does anyone have any experience interfacing Stamp with this chip?

    No experience, but looks easy to do. There are cheaper chips with fewer features for people who don't need them all. These other coprocessors are also smaller because they don't need so many I/O pins.
