4-Bit Microcontroller with Built-in LCD Driver and Melody Circuit
GENERAL DESCRIPTION
The MSM64152A (1.5 V)/64152AL (3.0 V) is a high-performance 4-bit microcontroller that
incorporates Oki-original CPU core nX-4/20.
The MSM64152A/64152AL has an LCD driver for up to 104 segments, an event counter, and a
melody circuit. It is best suited for applications such as clocks and LCD games.
