VAMAHA"L~I YM3439 Software-Controlled Sound Generator (SSGC) • OUTLINE Yl13-139 (SSGC) is a sound source LSI thaL controlled by micro-processor. This LSI incorporaLes three squure·wave generators, one noise generaLor and a envelope genernlor, which enables melody and effect sound generation. The LSI is made by CMOS process , and is comp'1tilile wilh Yl121-1~ (SSG). II FEATUHES • Low power consumption of CMOS process. • Register compatible with YM2149 (SSG) . • Sound source wiLh three square-wave generators and one noise gc ner;itor. • 8-octave wide sound ran ge. • SmooLh feeling sound decay is possible wiLh 5-liiL envelope generator. • BuilL-in 3-channel 5-bit DAC. • CPU parallel interface using 8-bit duta bus. • BuilL·in 2 channel 8-bit I/0 ports enables i11Lerface wiLh external sysLems.
