CXP85490 Overview
The CXP85400/85490 are CMOS 8-bit 1-chip microputers 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.
