GENERAL DESCRIPTION

The MSM6352 is a high-performance 4-bit microcontroller employing complementary metal oxide semiconductor technology. The use of this device for a repertory telephone, which employed a conventional microcomputer that was difficult to be configured in a single-chip device, allows a compact and high-performance telephone set to be monufactured easily.
