OPERATING FEATURES
Power-up
When the power supply is turned on, V
from V
During this time, the Chip Select (S) must be al-
lowed to follow the V
lowed to float, but should be connected to V
a suitable pull-up resistor.
As a built-in safety feature, Chip Select (S) is edge
sensitive as well as level sensitive. After Power-
up, the device does not become selected until a
falling edge has first been detected on Chip Select
(S). This ensures that Chip Select (S) must have
been High, prior to going Low to start the first op-
eration.
Device Internal Reset
In order to prevent inadvertent Write operations
during Power-up, a Power On Reset (POR) circuit
is included. At Power-up (continuous rise up of

The SRWD, BP1 and BP0 bits of the Status Reg-
ister are unchanged from the previous power-
down (they are non-volatile bits).
Prior to selecting and issuing instructions to the
memory, a valid and stable V

until the end of the transmission of the instruction

Power-down
At Power-down, the device must be deselected
and in Standby Power mode (i.e. no internal Write
cycle in progress). Chip Select (S) should be al-
lowed to follow the voltage applied on V
Active Power and Standby Power Modes
When Chip Select (S) is Low, the device is select-
ed, and in the Active Power mode. The device
consumes I

When Chip Select (S) is High, the device is dese-
lected. If an Erase/Write cycle is not currently in
progress, the device then goes into the Standby
Power mode, and the device consumption drops
to I
Hold Condition
The Hold (HOLD) signal is used to pause any se-
rial communications with the device without reset-
ting the clocking sequence.
During the Hold condition, the Serial Data Output
(Q) is high impedance, and Serial Data Input (D)
and Serial Clock (C) are Don’t Care.
To enter the Hold condition, the device must be
selected, with Chip Select (S) Low.
Normally, the device is kept selected, for the whole
duration of the Hold condition. Deselecting the de-
vice while it is in the Hold condition, has the effect
of resetting the state of the device, and this mech-
anism can be used if it is required to reset any pro-
cesses that had been in progress.
The Hold condition starts when the Hold (HOLD)
signal is driven Low at the same time as Serial
Clock (C) already being Low.
The Hold condition ends when the Hold (HOLD)
signal is driven High at the same time as Serial
Clock (C) already being Low.
