Reset (RST#)
The Reset pin can be used to apply a Hardware Reset to the memory. A hardware reset is
achieved by holding Reset Low, V

Ready/Busy output (RY/BY#)
The Ready/Busy pin is an open-drain output that can be used to identify when the device is
performing a program or erase operation. During program or erase operations Ready/Busy
is Low, V
Read mode, Auto Select mode and Erase Suspend mode.
After a Hardware Reset, Bus Read and Bus Write operations cannot begin until Ready/Busy
becomes high-impedance. See
Figure
The use of an open-drain output allows the Ready/Busy pins from several memories to be
connected to a single pull-up resistor. A low value will then indicate that one, or more, of the
memories is busy. The 10K ohm or bigger resistor is recommended as pull-up resistor to
achieve 0.1V V
Byte/Word organization select (BYTE#)
The BYTE# pin is used to switch between the x8 and x16 Bus modes of the memory. When
Byte/Word organization select is Low, V
