Description

The CXP86400/86490 are CMOS 8-bit single chip microcomputers that serve as both piggyback and evaluator. The CXP86400/86490 are developed for evaluating the function of the CXP86440/86448/86460. Note that the CXP86400 corresponds to the fixed font and the CXP86490 corresponds to the custom font respectively.
