8 Megabit (1 M x 8-Bit/512 K x 16-Bit)CMOS 3.0 Volt-only Boot Sector Flash Memory

Spansion Inc. 

Data Sheet

The Erase Suspend feature enables the user to put erase on hold for any period

of time to read data from, or program data to, any sector that is not selected for

erasure. True background erase can thus be achieved.

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 the boot-up firmware from the Flash memory.

The device offers two power-saving features. When addresses are stable for a

specified amount of time, the device enters the automatic sleep mode. The

system can also place the device into the standby mode. Power consumption is

greatly reduced in both these modes.

Spansion’s Flash technology combines years of Flash memory manufacturing ex-

perience to produce the highest levels of quality, reliability and cost

effectiveness. The device electrically erases all bits within a sector simulta-

neously via Fowler-Nordheim tunneling. The data is programmed using hot

electron injection.
