1998 MSM64158A/64158AL Previous version: Mar.
1996 4-Bit Microcontroller with Built-in LCD Driver and Melody Circuit The MSM64158A (1.
5 V)/64158AL (3.
0 V) is a high-performance 4-bit microcontroller that incroporates Oki-original CPU core nX-4/20.
The MSM64158A/64158AL has an LCD driver for up to 144 segments, an event counter, and a melody circuit.
It is best suited for applications such as clocks and LCD games.
