W55FXX
SERIAL FLASH EEPROM SERIES
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 PowerSpeech^TM series.
The single voltage supply eliminates the need for an extra pump circuit during programming and
erasing.
