Sony CXP85490, CXP85400 Datasheet

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.
