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 PowerSpeechTM series.
The single voltage supply eliminates the need for an extra pump circuit during programming and
erasing.
FEATURES
• Provides CLK, ADDR, and DATA pins to operate with Winbond PowerSpeechTM series
• 512K/1M/2M memory sizes available
• Directly cascadable for longer duration
• Fast frame-write operation
− Frame (32 bits) program cycle time: 400 µS (typ.)
• Fast whole-chip-erase duration: 50 mS (max.)
• Read data access time: 500 nS (max.)
• Program/erase cycles: 10,000 (typ.)
• Data retention: 10 years (typ.)
• Low power consumption:
− Operating: 5 mA (typ.)
− Standby: 2 µA (typ.)
