TYPE
ADDRESS INPUTS : Inputs for addresses during read and write operations. Addresses
are internally latched during a write cycle.
DATA INPUT/OUTPUTS : Inputs data and commands during CUI write cycles; outputs
data during memory array, status register, 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.
CHIP ENABLE : Activates the device's control logic, input buffers, decoders, and sense
amplifiers. CE#-high deselects the device and reduces power consumption to standby
levels.
RESET/DEEP POWER-DOWN : Puts the device in deep power-down mode and resets
internal automation. RP#-high enables normal operation. When driven low, RP# inhibits
write operations which provide data protection during power transitions. Exit from deep
power-down sets the device to read array mode. RP# at V
lock-bit. Block erase, word write, or lock-bit configuration with V
spurious results and should not be attempted.
OUTPUT ENABLE : Controls 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.
READY/BUSY : Indicates the status of the internal WSM. When low, the WSM is
performing an internal operation (block erase, word write, or lock-bit configuration).
RY/BY#-high indicates that the WSM is ready for new commands, block erase is
suspended, and word write is inactive, word write is suspended, or the device is in deep
power-down mode. RY/BY# is always active and does not float when the chip is
deselected or data outputs are disabled.
BLOCK ERASE, WORD WRITE, LOCK-BIT CONFIGURATION POWER SUPPLY :
For erasing array blocks, writing word, or configuring lock-bits. With V
memory contents cannot be altered. Block erase, word write, and lock-bit configuration
with an invalid V
results and should not be attempted.
DEVICE POWER SUPPLY : Internal detection configures the device for 2.7 V, 3.3 V or
5 V operation. To switch from one voltage to another, ramp V
ramp V
attempts to the flash memory are inhibited. Device operations at invalid V
(see Section 6.2.3 "DC CHARACTERISTICS") produce spurious results and should
not be attempted.
GROUND : Do not float any ground pins.
NO CONNECT : Lead is not internal connected; recommend to be floated.
