Outline
YMF795 is a sound source LSI to reproduce high quality melody and effect sound for in-car product. Yamaha's original FM synthesizer embedded as a sound source can create various timbres, and also a sequencer embedded can simultaneously generate up to four sounds with four different timbres without giving load to the controller. Serial port is prepared as a controller interface, and no restriction of data capacity is present because melody data is reproduced in real-time through FIFO. A built-in amplifier to drive the dynamic speaker with 500mW power allows connecting a speaker directly. This LSI is equipped with an analog-output pin also for the earphone jack. In addition, supporting the standby mode can reduce the consumption current to 1 A during the standby.
