Data Input/output 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.
WP# Write Protect To protect the top/bottom boot block from Erase/Program operation when
grounded.
RST# Reset To reset and return the device to Read mode.
CE# Chip Enable To activate the device when CE# is low.
OE# Output Enable To gate the data output buffers.
WE# Write Enable To control the Write operations.

Power Supply To provide power supply voltage: 2.7-3.6V

NC No Connection Unconnected pins.
RY/BY# Ready/Busy# To output the status of a Program or Erase operation
RY/BY# is a open drain output, so a 10K - 100K pull-up resistor is required
to allow RY/BY# to transition high indicating the device is ready to read.
