PIN DESCRIPTION
A0–A16
A
hold addresses during write cycles.
CE
Chip Enable active low input activates the chip’s con-
trol logic and input buffers. Chip Enable high will dese-
lect the device and operates the chip in stand-by mode.
DQ0–DQ7
Data Inputs during memory write cycles. Internal
latches hold data during write cycles. Data Outputs
during memory read cycles.
NC
No Connect-corresponding pin is not connected
internally to the die.
OE
Output Enable active low input gates the outputs of the
device through the data buffers during memory read
cycles. Output Enable is high during command
sequencing and program/erase operations.

WE
Write Enable active low input controls the write function
of the command register to the memory array. The tar-
get address is latched on the falling edge of the Write
Enable pulse and the appropriate data is latched on the
rising edge of the pulse. Write Enable high inhibits
writing to the device.
