ft809
ft1601y is a midi interface based hi-grade audio synthesis processor mixed signal vlsi, developed specifically for music ringers and game sounds. with a built in mixer, equalizer, and speaker amplifiers, this vlsi is an ideal device for cellular phones, pdas and other mobile devices.
with high quality on-chip wavetables compatible with general midi sound set, ft1601y is capable of playing 40 polyphonies simultaneously.
ft1601y has a built-in hardware sound synthesizer that is capable of complex sound replay with minimal loading by the host cpu. this vlsi also has built-in led controller, vibrator controller and internal pll filter. a fantastic music ringer subsystem can readily be built around this chip with minimum external components and cost.
