YMF781 产品详情

■Overview

YMF781 (APL-1: hereinafter described as APL-1) is an LSI, integrating synthesizer, ADPCM decoder and a CPU for

control in one chip.  Various sounds used in common automobiles, motor cycles, and electric appliances, suchas alarm sound, operation sound, and melody sound, and pseudo engine sound for an electric car can be generated with a little CPU load. A control CPU incorporated enables APL-1 control by a simple command (API) from the external host CPU.



■Features

●CPU is incorporated and enabling controls for synthesizer and other functions by the simple commands.

●Stereo hybrid synthesizer that can generate up to 64 voices simultaneously.

●Time change low pass filter function by AL (Analog Lite) synthesizer is built in.

●ADPCM and PCM stream playback is possible.

●The default tone for FM and Wave Table synthesizer isbuilt in ROM, and registration of a tone to SRAM is possible.

●Speaker amplifier and equalizer circuit is built in.

●Stereo / monaural analog output terminal is equipped.

●Two control circuits for LED lighting are built in. 

   The synchronization with contents and compulsive control are also possible.

●The inspection function is built in as an externalmemory interface function.

●APL-1 control interface

   Three interfaces are provided: Clock Sync Serial, Asynchronous Serial (UART) and Command Port (Mode, which identify commands by the changes of bus.)

●Power down function is built in.

●Input and output port

   Some terminals can be used as an Input/Output port, which can be controlled from the host CPU.

●Malfunction prevention function owing to the electrostatic noise and electromagnetic noise is built in.

●Core power supply    3.3V (3.0V to 3.6V)

●I/O power supply    3.3V and 5.0V are changed. 3.3V (3.0V to 3.6V)   5.0V(4.75V to 5.25V)

●Speaker amplifier power supply    3.3V (3.0V to 3.6V)

●100pin plastic SQFP, pin lead plating with Pd-free (YMF781-SZ)
