Sony CXP85390A, CXP85300A Datasheet
CMOS 8-bit 1-chip Microcomputer
Description
The CXP85300A/85390A are CMOS 8-bit 1-chip
microcomputers 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.
