CXP85400/85490
CMOS 8-bit 1-chip Microcomputer
Description
The CXP85400/85490 are CMOS 8-bit 1-chip
microcomputers that serve as both piggyback and
evaluator. The CXP85400/85490 are developed for
evaluating the function of the CXP85452/85460.
Note that CXP85400 corresponds to the fixed font,
and CXP85490 corresponds to the custom font
respectively.
