Product Summary
The YMZ280B-F is a PCM/ADPCM decoder for game machines taht simultaneously plays back eight voices. Each voice data of the YMZ280B-F read from the external memory at the specified pitch is individually processed on the total level and panpot, and output in a 16-bit stereo data format. The voice data format of the YMZ280B-F can be selected from 4-bit ADPC, 8-bit PCM and 16-bit PCM, according to the applications. Maximum external memory address space of 16M bytes allows a large amount of voice data usage.
