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.
CMOS IC
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
