This is a multifunction LSI for amusement devices with graphics, sound, LED/motor control functions. By integrating these functions into one chip, we were able to improve reliability and reduce system costs.     The Graphics LSI AG series can function as a display system of amusement equipment and digital equipment at high cost performance.     The Sound LSI AS series is a highly compressed sampling sound generator LSI. it provides a compact,high-quality sound system thanks to its sound generator ROM.       The LED driver LSI AL series is an LSI that efficiently controls the LEDs of amusement devices. It performs serial connections between controllers and drivers, thereby realizing simplified interconnection.
