Description
The CXP85200A/85290A are CMOS 8-bit 1-chip microcomputers that serve as both piggyback and evaluator. The CXP85200A/85290A is developed for evaluating the function of the CXP85112B/85116B/85220A/85224A/85228A/85232A.
Note that CXP85200A corresponds to the fixed font, and CXP85290A corresponds to the custom font respectively.
