Technical content

SVM7561Series is the CMOS melody IC that generates melodies and chimes according to the music informa- tion programmed in the built-in mask ROM. The melody IC is provided with two built-in independent sound sources of main melody and accompaniment, and the 512-step capacity ROM for each sound source can be allocated to 16 songs, the maximum. When an 8 pins package is adopted, a CR oscillator will be able to be contained in the IC. So, the melody IC is ideal for miniaturized portable telephones and can generate high quality various receive melodies. I FEATURES G Number of songs : Up to 16 songs G Melody ROM : 512 steps (containing main melodies and accompaniments) G Sound source : Two sounds (Square waves) G Compass : One pattern can be selected by the mask option out of the four patterns of C4 to G6/C3 to G5/C4 to C7#/C3# to C6# G Musical interval : 16 sounds of main melodies and accompaniments in the selected compass. G Music selection : Serial selection with a terminal G Sound generator : Speaker drive (External amplifier) G Oscillator : Built-in CR oscillation/External input (to be selected by mask option) G Play mode : Level hold/One shot (to be selected by mask option) SOP3A-8pin G Shipping pattern : SOP3A-8Pin package G Low voltage operation : • Low power oscillator depending on the built-in voltage stabilizer

  • Standby mode in which the internal IC circuits stop when no music is played. G Power supply voltage : 0.9 to 5.5V G Current consumption : • Target 1.0µA (during standby)
  • Target 200µA (during operation) I TERMINAL EXPLANATION No. Terminal name Function

Terminal Terminal Terminal Built-in No. Name Attribute, Pull-down Terminal Function Input/Output Resistor 1 XRST Input Without For inputting reset signals.

  • The whole internal logic will be initialized when the “L” level voltage is applied.
  • A song to be played is selected following the initialization.
  • When the “H ” level voltage is applied, the internal logic initialization will end and a melody will be able to be selected/played.
  • Since the pull-down resistor is not provided to this terminal, do not leave this terminal open.

2 OSC (NC) Without 1) When selecting “Built-in CR Oscillation” as the reference signal source

optionally, this terminal no connect. (Input) 2) When selecting “External Clock Input” as the reference signal source optionally, input the square wave of 32.768kHz as the reference signal source. 3V SS Power supply – GND (0V) 4 TEST Input With For inputting test signals.

  • Use this terminal when evaluating functions of this IC.
  • Never apply the “H ” level voltage to this terminal.
  • Though this terminal is provided with the pull-down resistor, we recom- mend you to connect this terminal to VSS (and apply the “L” level volt- age) all the time in order to prevent malfunction. 5 MT Input With For inputting play start signal.
  • When the “H ” level voltage is applied, the operation mode will be se- lected and play start/stop is controlled according to the optionally se- lected play mode.
  • The built-in noise eliminator enables to examine input pulse widths.
  • When an input is judged as insufficient pulse width like noise, the standby mode will selected.
  • The pull-down resistor is provided to this terminal. 6 SEL Input With For inputting music selection signals.
  • As input signals start up, 16 songs can be selected cyclically.
  • Since this terminal is not provided with noise eliminator, apply input sig- nals not affected by noise/chattering.
  • Though this terminal is provided with the pull-down resistor, the pull- down resistor is turned off and “high impedance input” prevails the termi- nal in the standby mode. So, be sure to apply “L” level or “H ” level voltage to the terminal.
  • When the operation mode is selected, the pull-down resistor will turn on.
  • Input signals become invalid during play, but when the play mode returns to the standby mode and the “H ” level voltage is applied to this terminal, the music will proceed to another selected one. 7V DD Power supply – Power supply terminal (0.9 to 5.5V)

8 OUT Output – For outputting sound signals

  • Acoustic signals of main melody and accompaniment are mixed the out- put.
  • Acoustic signals are output as square waves.
  • When “Envelopment Attachment” is selected optionally, acoustic signals will be attenuated by the preset time constant.
  • Connect this terminal to the input terminal of the preamplifier through a volume control resistor or coupling capacitor. Notes: 1.NC = Non connection (Open or release) 2.Terminal numbers are for plastic PKGs. (S0P 8pin)

But other circuits will operate normally within the specification range. 2.When a main melody and the accompaniment are attached at the same time and the play signal is output from each sound source. 3.When the reference signal source is the external clock input, the voltage stabilizer will always stop the operation.
