CXP85390A Description
The CXP85300A/85390A are CMOS 8-bit 1-chip microputers that serve as both piggyback and evaluator. The CXP85300A/85390A are developed for evaluating the function of the CXP85324A/CXP 85332A/85340A. Note that CXP85300A corresponds to the fixed font, and CXP85390A corresponds to the custom font respectively.
