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.)
