IZ8057
MULTI MELODY GENERATOR WITH ACCOMPANEMENT
DESCRIPTION
The IZ8057 series is a CMOS LSI chip designed for use in advance clock products. It is
designed to play the melodies
according to previously programmed information. The IZ8057 is capable of generating songs
with or without the bell sound effect.
By pushing the sequence trigger key, all songs can be sequentially selected and played with
autostop function This device also
includes a buffer for directly drive piezoelectric buzzer and a pre-amplifier that provides a
simple interface to the drives circuit.
The IZ8057 has LED terminal for direct drive light emitting diode with rhythm of melody.
Upon customer’s request, new melodies may be programmed.

FUNCTIONAL DESCRIPTION
Oscillator Circuit
The oscillation frequency is used as a time base for tone and tempo generators, the accuracy
of which affects the quality of which
affects the quality of the melody generator.
Tempo Generator
There are 14 tempos available in this embodiment: 82, 88, 95, 103, 112, 123, 137, 154, 176,
205, 246, 308, 410 and 615 notes per minute.
Tone Generator
The tone generator is a programmed divider. The tone frequencies are created by dividing
the oscillator frequencies with M,
where M is an integer from 32 to 127. There are 27 tones selectable in this embodiment,
including end code.
Rhythm Generator
The rhythm generator is also a programmed divider and is used to generate the beat for each
tone. In this embodiment, 15 beats
are available as follows: 1/4, 1/2, 3/4, 1, 5/4, 3/2, 7/4, 2, 9/4, 5/2, 11/4, 13/4, 7/2 and 15/4.
ROM
The mask ROM stores the tempo, tone and rhythm data. The ROM sends these data to
respective generators so as to control
the tempo of each song, the tone codes and the rhythm codes.
LED Blinking
The blinking of the light emitting diode (LED) is matched with rhythm of the melody.
Envelope Circuit
The envelope circuit made the melody and accompanement output MTO decreases
exponentially.
Pre-Amplifier
The Pre-Amplifier together with external P-N-P and N-P-N transistors works as audioamplifier. In application modulated tone
signal MTO should be connect to the input MI1 of the pre-amplifier through capacitor.
Feedback resistor must be connected to
obtain the proper bias for the pre-amplifier stage. In the standby state the pre-amplifier is
disabled, and OP1 is pulled up to V SS ;
OP2 is pulled down to V CC.
The Output Buffer
The Output Buffer amplifies signal from input MI2 and establishes two output signals BD, BDN
for directly drive piezo buzzer.
