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.

FEATURES

* Range of operating voltage: 0.9~5.5V

* Reference signal source frequency: 32.768KHZ,47.520KHZ(mask

option selection)

* Options :

1. changing the melody midway during performance: Possible or

not possible (mask option selection)

2. selection of the reference sound frequency: when selecting the

signal source frequency of 32.768kHz, A4=440Hz(standard) or

C4=256Hz when selecting the signal source frequency of

47.520kHz: A4=440Hz

3. Selection of performance sound range: when selecting the

signal source frequency of

32.768kHz, A4=440Hz: G6~C4 or G5~C3

32.768kHz, A4=256Hz: C7~C4 or C6~C3

47.520kHz, A4=440Hz: C7~C4 or C6~F3

4. Choices of the reference signal source: External clock input or

integrated RC oscillator (using both of the integrated C and R)

or integrated RC oscillation (using the integrated C only but the

R is for external installation)

5. performance method choice :

Level hold

one shot C

one shot A

* Attenuation of sound: integrated envelope

adding circuit

* Loudspeaker drive: not equipping an

amplifier(an extremely installed amplifier

should be used)

* Output Impedance :

Max: 222k

Min :68k
