CXP85490 - 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.
