DESCRIPTION
UTC 15600 Series is a CMOS IC circuits which contain a
programmed mask ROM to generate chord music. The capacity of
the ROM being used for storage of such music information is of
128 words and up to two numbers of music melodies under two
different sound sources can be optioned for storage into it. Also,
the total integration (for mask option) of the RC oscillation circuit is
builted in. Moreover, a small-sized package can be suitable for
space –saving applications.
„

DESCRIPTION
When the external clock mode is selected by mask option:
Enter square waves of 32.768kHz or 47.520kHz to the
OSC1 pin as the reference signal source.
2. When the integrated RC oscillation is selected by mask
option:
When using an external ”R”, insert a resistor between the
OSC1 and OSC2 to adjust the oscillation frequency by the
resistance of the resistor.
When using integrated RC, keep the OSC1 and OSC2
open.
Negative supply pin or grounding pin
Integrated pull down.
when TEST is “high” and MT pin is “high, the device goes into
test mode .when IC goes into working, test should be tied to
VSS.
Integrated pull down .
When “high” level is input, the device goes into working mode to
control starting and stopping of the performance in accordance
with the performance method being designated by the mask
option, and that the device has the debnounce circuitry inside, it
is of no effect that the pulse is short of 32ms or 47ms.
Integrated pull down.
Melody 1 and melody 2 can be selected in the binary code by
entering “0”or “1” into this pin.
“Changing the melody midway during performance –not
possible or possible” is selected by mask option.
Power supply
With the audio signals, the key melody and accompaniment,
respectively, are attenuated under a certain time constant and
respective output s of the key melody and accompaniment are
mixed by the mixing resistor before being output.
This pin should therefore be connected to input pin of a pre-amp
via a variable resistor for volume control , coupling-capacitor,
etc

Note: 1. Under the RC oscillation mode. When the supply voltage drops below the voltage being generated the
internal constant voltage circuit, the RC oscillation frequency goes down below the prescribed level to
reduce the tempo and to bring down the pitch corresponding to the downward deviation of the oscillation
frequency. Other circuits function normally under the prescribed specifications.
2. This value is a reference value. Because current consumption varies depending on the programmed pitch,
tempo, used notes and address location with each ROM.
