Sony CXP86400, CXP86490 Datasheet

CXP86400/86490

CMOS 8-bit Single Chip Microcomputer

Description

The CXP86400/86490 are CMOS 8-bit single chip
microcomputers that serve as both piggyback and
evaluator. The CXP86400/86490 are developed for
evaluating the function of the CXP86440/86448/86460.

Note that the CXP86400 corresponds to the fixed
font and the CXP86490 corresponds to the custom
font respectively.

Features
