High speed and Simple 4-Bit Microcontroller
This version: S_Mep_S._M19₆9₄8₂₂
Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM6422 is a low-power, single-chip device implemented in complementary metal-oxide
semiconductor technology.
The MSM6422 can be used in place of logic ICs configured around a main CPU, or for small-scale
systems such as home electronic equipment.
