Hardware Data Protection
The command sequence requirement of unlock cycles for programming or erasing
provides data protection against inadvertent writes (refer to Tables
10
–
11
for
command definitions). In addition, the following hardware data protection mea-
sures prevent accidental erasure or programming, which might otherwise be
caused by spurious system level signals during V
CC
power-up and power-down
transitions, or from system noise.
Low V
CC
Write Inhibit
When V
CC
is less than V
LKO
, the device does not accept any write cycles. This pro-
tects data during V
CC
power-up and power-down. The command register and all
internal program/erase circuits are disabled, and the device resets. Subsequent
writes are ignored until V
CC
is greater than V
LKO
. The system must provide the
proper signals to the control pins to prevent unintentional writes when V
CC
is
greater than V
LKO
.
Write Pulse “Glitch” Protection
Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write
cycle.
