Informatio n

Low VCC Write Inhibit

When VCC is less than VLKO, the device does not accept any write cycles. This pro-

tects data during VCC power-up and power-down. The command register and all

internal program/erase circuits are disabled, and the device resets to the read

mode. Subsequent writes are ignored until VCC is greater than VLKO. The system

must provide the proper signals to the control pins to prevent unintentional writes

when VCC is greater than VLKO.

Write Pulse “Glitch” Protection

Noise pulses of less than 3 ns (typical) on OE#, CE# or WE# do not initiate a write

cycle.

Logical Inhibit

Write cycles are inhibited by holding any one of OE# = VIL, CE# = VIH or WE# =

VIH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a

logical one.

Power-Up Write Inhibit

If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept

commands on the rising edge of WE#. The internal state machine is automatically

reset to the read mode on power-up.
