Winbond Electronics Corporation W551C080
The W551Cxxx series is a serial voice memory IC designed to interface directly with Winbond PowerSpeech™ , BandDirector™ , and ViewTalk™ family ICs to meet the increasing market demand for longer playback duration. The W551Cxxx uses the same three-pin serial interface that Winbond serial flash memory W55Fxx uses, which makes it easier to simulate and verify the memory contents in advance. The following table shows the part numbers in the W551Cxxx series and their respective memory density.| Part No. | W551C080 |

GENERAL DESCRIPTION
In addition, the W551Cxxx also provides a "Self-test mode" to verify the voice memory contents easily and quickly, and some members of the W551Cxxx series allow W551Cxxx chips to be “cascaded” to further lengthen playback duration. W551Cxxx Serial Voice Memory is used to store pre-determined data.
