Write Enable (W)
The Write Enable, W, controls the Bus Write operation of the memory’s Command Interface.
Reset/Block Temporary Unprotect (RP)
The Reset/Block Temporary Unprotect pin can be used to apply a Hardware Reset to the
memory or to temporarily unprotect all Blocks that have been protected.
A Hardware Reset is achieved by holding Reset/Block Temporary Unprotect Low, V

Ready/Busy Output (RB)
The Ready/Busy pin is an open-drain output that can be used to identify when the memory
array can be read. Ready/Busy is high-impedance during 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
Characteristics (TA = 0 to 70 °C, –40 to 85 °C or –40 to 125 °C)
Temporary Unprotect ac
During Program or Erase operations Ready/Busy is Low, V
during Read/Reset commands or Hardware Resets until the memory is ready to enter Read
mode.
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
