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.
