ML2870AHBZE60
ML2870A is a highly sophisticated PCM sound generator LSIs
primarily, but not exclusively, designed for cell phones and PDAs.
It is also capable of rplaying ADPCM and compressed speech and
sound data. With an on-chip high-quality General MIDI sound set,
the ML2870A plays 32 polyphonies simultaneously with 16 timbres.
Using the on-chip three FIFOs which store musical score data,
MIDI messages and ADPCM audio data, a fantastic music ringer
subsystem can readily be built around this chip. Also provided are
ports to drive a ringing vibrator, an LCD backlight and four PWMdriven
LED outputs. CPU control is possible either in parallel or
serial, while a comprehensive register structure allows easy
programming. The chip contains an orchestra of musical instruments,
a symphony on silicon, for modern cell phones and more.
