UM3482 Bowin Microelectronics _________________________________________________________ UM3481A Multi-Instrument Melody Generator Features • Powered by a 1.5V battery • Low standby current • 512-note memory, up to 16 songs • 8 playing modes by user setting • One built-in RC oscillator • 8 beats selectable • 3 timbres - piano, organ, and mandolin • 5 tempos available through mask setting • 14 tones selectable • On-chip envelope modulator and pre-amplifier General Description The UM3481 series is a mask-ROM-programmed multi-instrument melody generator , implemented by CMOS technology. It is designed to play the melody according to the previously programmed information and is capable of generating 16 songs with 3 instrument effects : piano, organ and mandolin. The device also includes a pre-amplifier which provides a simple interface to the driver circuit. The M3481 series is intended for applications such as toys, door bells, music box, melody clock/timers and telephones.
