MSM6352

Built-in DTMF Generator 4-Bit Microcontroller

This version: JManS.M19693852

Previous version: Mar. 1996

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.
