CXP85300A/85390A
CMOS 8-bit 1-chip Microcomputer
Piggyback/
evaluator type
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.
64 pin PSDIP (Ceramic) 64 pin PQFP (Ceramic)
