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. DQ

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: Resets the device internal automation. RP#-high enables normal operation. When driven
low, RP# inhibits write operations which provides data protection during power transitions. Exit
from reset mode sets the device to read array mode. RP# must be V
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.

READY/BUSY#: Indicates the status of the internal WSM. When low, the WSM is performing an
internal operation (block erase, full chip erase, word/byte write or lock-bit configuration).
RY/BY#-high Z indicates that the WSM is ready for new commands, block erase is suspended,
and word/byte write is inactive, word/byte write is suspended, or the device is in reset mode.
