ML63187/63189B

4-Bit Microcontroller with Built-in 1024-Dot Matrix LCD Drivers and Melody Circuit,

Operating at 0.9 V (Min.)

GENERAL DESCRIPTION

TheML63187/63189BisaCMOS4-bitmicrocontrollerwithbuilt-in1024-dotmatrixLCDdrivers

and operates at 0.9 V (min.). The ML63187/63189B is suitable for applications such as games,

toys, watches, etc. which are provided with an LCD display.

The ML63187/63189B is an M6318x series mask ROM-version product of OLMS-63K family,

which employs Oki's original CPU core nX-4/250.

FEATURES
