ADDRESS INPUTS: Inputs for addresses. 32M: A
DATA INPUTS/OUTPUTS: Inputs data and commands during CUI (Command User
Interface) write cycles, outputs data during memory array, status register, query code and
identifier code reads. Data pins float to high-impedance (High Z) when the chip or
outputs are deselected. Data is internally latched during an erase or program cycle.
CHIP ENABLE: Activates the device’s control logic, input buffers, decoders and sense
amplifiers. CE#-high (V

power-up or reset mode, the device is automatically set to read array mode. RST# must
be low during power-up/down.
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 CE# or WE# (whichever goes high first).
DEVICE POWER SUPPLY (2.7V-3.6V): With V

GROUND: Do not float any ground pins.
NO CONNECT: Lead is not internally connected; it may be driven or floated.
