    YMU757B MA-1C Outline 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 simultaneously without placing a load to the controller. The 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, it is possible to connect the speaker directly. This LSI also has an analog-output terminal for the phone jack.
