INPUT
ADDRESS INPUTS:
Memory addresses are internally latched during a
program or erase cycle.
8-Mbit: A[0-18], 16-Mbit: A[0-19]
DATA INPUTS/OUTPUTS:
Inputs array data on the second CE# and
WE# cycle during a Program command. Inputs commands to the
Command User Interface when CE# and WE# are active. Data is
internally latched. Outputs array, configuration and status register data.
The data pins float to tri-state when the chip is de-selected or the outputs
are disabled.

INPUT/OUTPUT
DATA INPUTS/OUTPUTS:
Inputs array data on the second CE# and
WE# cycle during a Program command. Data is internally latched.
Outputs array and configuration data. The data pins float to tri-state when
the chip is de-selected.
CE#
INPUT
CHIP ENABLE:
Activates the internal control logic, input buffers,
decoders and sense amplifiers. CE# is active low. CE# high de-selects
the memory device and reduces power consumption to standby levels.
OE#
INPUT
OUTPUT ENABLE:
Enables the device’s outputs through the data
buffers during a read operation. OE# is active low.
WE#
INPUT
WRITE ENABLE:
Controls writes to the command register and memory
array. WE# is active low. Addresses and data are latched on the rising
edge of the second WE# pulse.
RP#
INPUT
RESET/DEEP POWER-DOWN:
Uses two voltage levels (V
IL
, V
IH
) to
control reset/deep power-down mode.
When RP# is at logic low, the device is in reset/deep power-down
mode
, which drives the outputs to High-Z, resets the Write State
Machine, and minimizes current levels (I
CCD
).
When RP# is at logic high, the device is in standard operation
.
When RP# transitions from logic-low to logic-high, the device resets all
blocks to locked and defaults to the read array mode.
WP#
INPUT
WRITE PROTECT:
Controls the lock-down function of the flexible
Locking feature
When WP# is a logic low, the lock-down mechanism is enabled
and
blocks marked lock-down cannot be unlocked through software.
When WP# is logic high, the lock-down mechanism is disabled
and
blocks previously locked-down are now locked and can be unlocked and
locked through software. After WP# goes low, any blocks previously
marked lock-down revert to that state.
See Section 3.3 for details on block locking.

SUPPLY
DEVICE POWER SUPPLY:
[2.4 V–3.0 V] Supplies power for device
operations.
