OPERATING FEATURES
Power-Up
When the power supply is turned on, VCC rises
from VSS to VCC.
During this time, the Chip Select (S) must be al-
lowed to follow the VCC voltage. It must not be al-
lowed to float, but should be connected to VCC via
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.
Power On Reset: VCC Lock-Out Write Protect
In order to prevent inadvertent Write operations
during Power-up, each device include a Power On
Reset (POR) circuit. At Power-up, the device will
not respond to any instruction until VCC has
reached the Power On Reset threshold voltage.
This threshold is lower than the VCC min operating
Similarly, as soon as VCC drops from the normal
operating voltage, below the Power On Reset
threshold voltage, the device stops responding to
any instruction sent to it.
Prior to selecting and issuing instructions to the
memory, a valid stable VCC voltage must be ap-
plied. This voltage must remain stable and valid
until the end of the transmission of the instruction
and, for a Write instruction, until the completion o
the internal write cycle (tW).
Power-down
At Power-down, the device must be deselected.
Chip Select (S) should be allowed to follow the
voltage applied on VCC.
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
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 in to the Standby
Power mode, and the device consumption drops
to ICC1.
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 (as shown in Figure
6.).
The Hold condition ends when the Hold (HOLD)
signal is driven High at the same time as Serial
Clock (C) already being Low.
Figure 6. also shows what happens if the rising
and falling edges are not timed to coincide with
Serial Clock (C) being Low.
