CMOS MELODY IC q Enables to program up to 16 songs q Provided with two built-in independent sound sources q A 8-pin package s OVERVIEW
SVM7561Series is the CMOS melody IC that generates melodies and chimes according to the music information programmed in the built-in mask ROM. The melody IC is provided with two built-in independent sound sources of main melody and acpaniment, 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. s Features q Number of songs :

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# q Musical interval :
16 sounds of main melodies and acpaniments in the selected pass. q Music selection :
Serial selection with a terminal q Sound generator :
Speaker drive (External amplifier) q Oscillator :
Built-in CR oscillation/External input (to be selected by mask option) q Play mode :
Level hold/One shot (to be selected by mask option) SOP3A-8pin q Shipping pattern :
SOP3A-8Pin package q 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. q Power supply voltage : 0.9 to 5.5V q Current consumption :
- Target 1.0µA (during standby)
- Target 200µA (during operation)
