Name and Function
Asserted
State
Type
CS
Chip Select:
Asserting the CS pin selects the device.
W
hen the CS pin is deasserted, the device
will be deselected and normally be placed in the standby mode (not Deep Power-Down mode),
and the output pin (SO) will be in a high-impedance state.
W
hen the device is deselected, data
will not be accepted on the input pin (SI).
A high-to-low transition on the CS pin is required to start an operation, and a low-to-high
transition is required to end an operation.
W
hen ending an internally self-timed operation such as
a program or erase cycle, the device will not enter the standby mode until the completion of the
operation.
Low
Input
SCK
Serial Clock:
This pin is used to provide a clock to the device and is used to control the flow of
data to and from the device. Command, address, and input data present on the SI pin is always
latched on the rising edge of SCK, while output data on the SO pin is always clocked out on the
falling edge of SCK.
–
Input
SI
Serial Input:
The SI pin is used to shift data into the device. The SI pin is used for all data input
including command and address sequences. Data on the SI pin is always latched on the rising
edge of SCK. If the SER/BYTE pin is always driven low, the SI pin should be a “no connect”.
–
Input
SO
Serial Output:
The SO pin is used to shift data out from the device. Data on the SO pin is always
clocked out on the falling edge of SCK. If the SER/BYTE pin is always driven low, the SO pin
should be a “no connect”.

Output
W
P
Write Protect:
W
hen the
W
P pin is asserted, all sectors specified for protection by the Sector
Protection Register will be protected against program and erase operations regardless of whether
the Enable Sector Protection command has been issued or not. The
W
P pin functions
independently of the software controlled protection method. After the
W
P pin goes low, the
content of the Sector Protection Register cannot be modified.
If a program or erase command is issued to the device while the
W
P pin is asserted, the device
will simply ignore the command and perform no operation. The device will return to the idle state
once the CS pin has been deasserted. The Enable Sector Protection command and Sector
Lockdown command, however, will be recognized by the device when the
W
P pin is asserted.
The
W
P pin is internally pulled-high and may be left floating if hardware controlled protection will
not be used. However, it is recommended that the
W
P pin also be externally connected to V
CC
whenever possible.
Low
Input
RESET
Reset:
A low state on the reset pin (RESET) will terminate the operation in progress and reset
the internal state machine to an idle state. The device will remain in the reset condition as long as
a low level is present on the RESET pin. Normal operation can resume once the RESET pin is
brought back to a high level.
The device incorporates an internal power-on reset circuit, so there are no restrictions on the
RESET pin during power-on sequences. If this pin and feature are not utilized it is recommended
that the RESET pin be driven high externally.
Low
Input
V
CC
Device Power Supply:
The V
CC
pin is used to supply the source voltage to the device.
Operations at invalid V
CC
voltages may produce spurious results and should not be attempted.
Ground:
The ground reference for the power supply. GND should be connected to the system
ground.
