CMOS 8-bit 1-chip Microcomputer
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.
