General Description
The Spansion S29WS256/128 are Mirrorbit
TM
Flash products fabricated on 110-nm process technology.
These burst mode Flash devices are capable of performing simultaneous read and write operations with
zero latency on two separate banks using separate data and address pins. These products can operate up
to 80 MHz and use a single V
CC
of 1.7 V to 1.95 V that makes them ideal for today’s demanding wireless
applications requiring higher density, better performance and lowered power consumption.

w ords each for factory and customer
20-year data retention ( typical)
Cycling Endurance: 100,000 cycles per sector
( typical)
RDY output indicates data available to system
Performance Characteristics
Command set compatible w ith J EDEC ( 42.4)
standard
Hardw are ( W P# ) protection of top and bottom
sectors
Dual boot sector configuration ( top and bottom)
Low V

Sector Protection
W rite operation status bits indicate program and
erase operation completion
Suspend and Resume commands for Program and
Erase operations
Unlock Bypass program command to reduce
programming time
Synchronous or Asynchronous program operation,
independent of burst control register settings
ACC input pin to reduce factory programming time
Support for Common Flash I nterface ( CFI )
