UNISONIC TECHNOLOGIES CO., LTD 15600 CMOS IC MELODY IC 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.

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 1.

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.
