Name and Function
ADDRESS INPUTS: Inputs for addresses during read and write operations. Addresses are
internally latched during a write cycle.
A 0 : Byte Select Address. Not used in x16 mode(can be floated).
A 1 -A 4 : Column Address. Selects 1 of 16 bit lines.
A 5 -A 15 : Row Address. Selects 1 of 2048 word lines.
A 16 -A 20 : Block Address.
DATA INPUT/OUTPUTS:
DQ 0 -DQ 7 :Inputs data and commands during CUI write cycles; outputs data during memory
array, status register, query, and identifier code read cycles. Data pins float to high-
impedance when the chip is deselected or outputs are disabled. Data is internally latched
during a write cycle.
DQ 8 -DQ 15 :Inputs data during CUI write cycles in x16 mode; outputs data during memory
array read cycles in x16 mode; not used for status register, query and identifier code read
mode. Data pins float to high-impedance when the chip is deselected, outputs are
disabled, or in x8 mode(Byte#=V IL ). Data is internally latched during a write cycle.
BANK ENABLE: Activates the device’s control logic, input buffers, decoders, and sense
amplifiers. When BE 0 # and BE 1L # "low", bank0 is in active. When BE 0 # and BE 1H # are
"low", bank1 is in active. BE 0 # and BE 1L #, BE 1H # must not be low at the same time.
RESET/DEEP POWER-DOWN: Puts the device in deep power-down mode and resets
internal automation. RP# V IH enables normal operation. When driven V IL , RP# inhibits
write operations which provides data protection during power transitions. Exit from deep
power-down sets the device to read array mode.
OUTPUT ENABLE: Gates the device’s outputs during a read cycle.
WRITE ENABLE: Controls writes to the CUI and array blocks. Addresses and data are
latched on the rising edge of the WE# pulse.
STS (RY/BY#): Indicates the status of the internal WSM. When configured in level mode
(default mode), it acts as a RY/BY# pin. When low, the WSM is performing an internal
operation (block erase, bank erase, (multi) word/byte write or block lock-bit configuration).
STS High Z indicates that the WSM is ready for new commands, block erase is
suspended, and (multi) word/byte write is inactive, (multi) word/byte write is suspended or
the device is in deep power-down mode. For alternate configurations of the STATUS pin,
see the Configuration command.
WRITE PROTECT: Master control for block locking. When V IL, Locked blocks can not be
erased and programmed, and block lock-bits can not be set and reset.
BYTE ENABLE: BYTE# V IL places device in x8 mode. All data is then input or output on
DQ 0-7 , and DQ 8-15 float. BYTE# V IH places the device in x16 mode , and turns off the A 0
input buffer.
BLOCK ERASE, BANK ERASE, (MULTI) WORD/BYTE WRITE, BLOCK LOCK-BIT
CONFIGURATION POWER SUPPLY: For erasing array blocks, writing bytes or
configuring block lock-bits. With V PP ≤ V PPLK , memory contents cannot be altered. Block
erase, bank erase, (multi) word/byte write and block lock-bit configuration with an invalid
V PP (see DC Characteristics) produce spurious results and should not be attempted.
DEVICE POWER SUPPLY: Internal detection configures the device for 2.7V, 3.3V or 5V
operation. To switch from one voltage to another, ramp V CC down to GND and then ramp
V CC to the new voltage. Do not float any power pins. With V CC ≤ V LKO , all write attempts to
the flash memory are inhibited. Device operations at invalid V CC voltage (see DC
Characteristics) produce spurious results and should not be attempted.
GROUND: Do not float any ground pins.
NO CONNECT: Lead is not internal connected; it may be driven or floated.
