HOLTEK J 4 HT3810 Series 128-Note Melody Generators Features Operating voltage: 2.4V~5.0V 7 tempo options: 469, 234, 156, 117, 94, 78, 67 2 Envelope sustain durations: 1 beat, 2 beat s 2 CHA sustain duration options: 1/8 beat or 1/4 beat One octave lower transposition output by bonding option Applications Telephones General Description The HT3810 series are single-chip 128-note melody generators implemented in CMOS tech- nology. A melody of 128-notes can be automat- ically played when power is switched on. A customer merely needs to supply a melody sample which can be programmed into the ROM by changing a mask layer during device fabrication. The IC contains two independent tone gener- ators, CHA sound accompaniment circuit, en- velope generator, time base generator and an output driver. With such powerful functions various special musical effects can be created, Pin Assignment Extremely few external components Drive an 8Q speaker through an NPN transistor Drive piezo directly Flashing follows one or both of the 2 tone generators Enclosed in a TO-92 package Toys such as Chords, Broken Chords, CHA sound accompaniments, etc. The mask option can be made to accommodate various melodies, tem- pos, envelopes and CHA sound duration. The LED driver may be set to flash following one or both of the two tone generators. The output driver can drive a piezo buzzer directly or an 8 ohm speaker through an external NPN transistor. The HT3810 series are ultra-mini- ature and require almost no external compo- nents for normal applications. They are offered in chip form or in a TO-92 package. Refer to the selection table for standard melodies. Block Diagram i Oscillator Tone D OUT HT3810 Circuit Generator Cireut [PY OUT Series i Circult PPO LED TEST!
