Outline
The YMU757B 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. In the stand-by mode, the power consumption can be
reduced to 1 A or less while waiting.
