ADDRESS INPUTS: Inputs for addresses. 64M: A
DATA INPUTS/OUTPUTS: Inputs data and commands during CUI (Command User
Interface) write cycles, outputs data during memory array, status register, query code,
identifier code and partition configuration register 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

RESET: When low (V

power-up or reset mode, the device is automatically set to read array mode. RST# must
be low during power-up/down.
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).
WRITE PROTECT: When WP# is V
