To output data during Read cycles and receive input data during Write cycles
Data is internally latched during a Write cycle. The outputs are in tri-state when
OE# or CE# is high.
DQ
15
is used as data I/O pin when in x16 mode (BYTE# = “1”)
A
-1
is used as the LSB address pin when in x8 mode (BYTE# = “0”)
To activate the device when CE# is low.
To gate the data output buffers
To control the Write operations
To reset and return the device to Read mode
To output the status of a Program or Erase operation
RY/BY# is a open drain output, so a 10KΩ - 100KΩ pull-up resistor is required
to allow RY/BY# to transition high indicating the device is ready to read.
To protect and unprotect top or bottom 8 KWord (4 outermost sectors) from Erase or
Program operation.
To provide 2.7-3.6V power supply voltage
