GENERAL DESCRIPTION

The W55FXX is a serial input/output flash EEPROM series that is typically used as the memory cell of a W51300 (voice recorder controller) or the ROM code emulator for the PowerSpeechTM series. The single voltage supply eliminates the need for an extra pump circuit during programming and erasing.
