GENERAL DESCRIPTION
The MSM63184B is a CMOS 4-bit microcontroller with built-in 640-dot matrix LCD drivers and
operates at 0.9 V (min.). The MSM63184B is suitable for applications such as games, toys,
watches, etc. which are provided with an LCD display.
The MSM63184B is an M6318x series mask ROM-version product of OLMS-63K family, which
employs Oki's original CPU core nX-4/250.
The MSM63P180 is the one-time-programmable ROM version of MSM63188, having one-time
PROM (OTP) as internal program memory.
The MSM63P180 is used to evaluate the software development.
FEATURES
