Ready/Busy Output (RB)
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
Erase Suspend mode.
After a Hardware Reset, Bus Read and Bus Write operations cannot begin until Ready/Busy
becomes high-impedance. See
AC
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 will then indicate that one, or more, of the
memories is busy.
Byte/Word Organization Select (BYTE)
The Byte/Word Organization Select pin is used to switch between the 8-bit and 16-bit Bus
modes of the memory. When Byte/Word Organization Select is Low, V
bit mode, when it is High, V

The command interface is disabled when the V

programming or erasing during this time then the operation aborts and the memory contents
being altered will be invalid.
A 0.1 μF capacitor should be connected between the V
ground pin to decouple the current surges from the power supply. The PCB track widths
must be sufficient to carry the currents required during program and erase operations, I
