A melody of 128-notes can be automatically played when power is switched on. such as Chords, Broken Chords, "CHA" sound accompaniments, etc. The mask option can be made to accommodate various melodies, tempos, envelopes and "CHA" sound duration. 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 generators, "CHA" sound accompaniment circuit, envelope generator, time base generator and an output driver. With such powerful functions various special musical effects can be created, 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-miniature and require almost no external components for normal applications. They are offered in chip form or in a TO-92 package. Refer to the selection table for standard melodies.
