ML63193
4-Bit Microcontroller with Built-in 1024-Dot Matrix LCD Driver and Melody Circuit.
GENERAL DESCRIPTION
The ML63193 is CMOS 4-bit microcontroller with built-in 1024-dot matrix LCD drivers (64 SEG. × 16 COM.),
and operates at 0.9 V (Min). The ML63193 is suitable for applications as games, toys, watches, remote controller,
etc. Which are provided with a LCD display.
The ML63193 is an M6318x series mask ROM-version product of OLMS-63K family, which employs Oki’s
original CPU core nX-4/250.
