4 Megabit (512 K x 8-Bit) CMOS 5.0 Volt-only/ Uniform Sector Flash Memory

Spansion Inc. 

DATA SHEET

outputs are placed in the high impedance state, inde-

pendent of the OE# input.

The device enters the CMOS standby mode when the

CE# pin is held at VCC ± 0.5 V. (Note that this is a more

restricted voltage range than VIH.) The device enters

the TTL standby mode when CE# is held at VIH. The

device requires the standard access time (tCE) before it

is ready to read data.

If the device is deselected during erasure or program-

ming, the device draws active current until the

operation is completed.

ICC3 in the DC Characteristics tables represents the

standby current specification.

Output Disable Mode

When the OE# input is at VIH, output from the device is

disabled. The output pins are placed in the high imped-

ance state.
