Datasheet Summary
VAMAHA"L~I
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 p'1tilile wilh Yl121-1~ (SSG).
