GENERAL DESCRIPTION
This version: Sep. 1998
MSM64155A/64155AL
Previous version: Mar. 1996
4-Bit Microcontroller with Built-in LCD Driver and Melody Circuit
The MSM64155A (1.5 V)/64155AL (3.0 V) is a high-performance 4-bit microcontroller that
incorporates Oki-original CPU core nX-4/20.
The MSM64155A/64155AL has an LCD driver for up to 240 segments, an event counter, and
melody circuits. It is best suited for applications such as clocks and LCD games.
