Description

The YMU75B is a high quality melody LSI for cellular phone handsets, supporting the data format for various applications including ringing and holding melody sounds. The built-in Yamaha's original FM synthesizer can create various timbres, and its built-in sequencer can produce up to 4 different sounds with 4 different timbres  imultaneously  without placing a load to the controller.

The YMU75B serial port controller interface enables real time reproduction of the melody data via FIFO, without the limitation of the data capacity.

With a built-in amplifier to drive the dynamic type speaker, YMU75B is possible to connect the speaker directly.

This LSI YMU75B also has an analog-output terminal for the phone jack. In the stand-by mode, the power consumption can be reduced to 1 A or less while waiting.
