SM1131

The SM1131 is a high sound-quality melody CMOS-IC capable of performing sixteen pieces or twelve pieces of music at the maximum.

Features of the SM1131 are:(1)a tempo may be specified on a piece by piece basis;(2)a CR oscillator or ceramic oscillator circuit is available on a mask-option basis;(3)a play may be forced to stop by means of a stop key;(4)a drum-cymbal percussion ferature is available;(5)a dynamic loudspeaker has a push-pull drive feature built in;(6)an extensible sound quality has the triple higher harmonics added;(7)a tremolo feature allows the triple higher harmonic to turn on and off.

The absolute maximum ratings of the SM1131 can be summarized as:(1)supply voltage:-0.3V to 7.0V;(2)input voltage:(VSS-0.2)V to (VDD+0.2)V;(3)operating temperature:-20 to +80;(4)storage temperature:-40 to +125;(5)soldering temperature:255;(6)soldering time:10s.
