The W551Cxxx series is designated to interface with Winbond PowerSpeech™ , BandDirector™ , and ViewTalk™ family ICs directly. Application with PowerSpeech™ , BandDirector™ , and ViewTalk™ the serial voice memory W551Cxxx can lengthen the playback duration to meet the increasing market demand on complicated scenarios. The W551Cxxx was already utilized the same serial interface as Winbond serial flash memory W55Fxx for designer to simulate & verify the memory contents in advance. Besides that, W551Cxxx also provides a "Self-test mode" to verify the voice memory contents easily and quickly.
