The hardware RESET# pin terminates any operation in progress and resets the internal state machine to
reading array data. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also
reset the device, enabling the system microprocessor to read boot-up firmware from the Flash memory
device.
The host system can detect whether a memory array program or erase operation is complete by using the
device status bit DQ7 (Data# Polling), DQ6/DQ2 (toggle bits), DQ5 (exceeded timing limit), DQ3 (sector erase
start timeout state indicator), and DQ1 (write to buffer abort). After a program or erase cycle has been
completed, the device automatically returns to reading array data.
The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the
data contents of other sectors. The device is fully erased when shipped from the factory.
Hardware data protection measures include a low VCC detector that automatically inhibits write operations
during power transitions. The device also offers another type of data protection at the sector level.
When the VPP pin = VIL, the entire flash memory array is protected.
Spansion Inc. Flash technology combines years of Flash memory manufacturing experience to produce the
highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a
sector. The data is programmed using hot electron injection.
