Write Enable (W)
The Write Enable input, W, controls writing to the command interface, input address and
data latches. Both addresses and data are latched on the rising edge of Write Enable.
During power-up and power-down a recovery time of 10 µs (min) is required before the
command interface is ready to accept a command. It is recommended to keep Write Enable
High during the recovery time.
Write Protect (WP)
The Write Protect pin is an input that gives a hardware protection against unwanted program
or erase operations. When Write Protect is Low, V

It is recommended to keep the Write Protect pin Low, V
Ready/Busy (RB)
The Ready/Busy output, RB, is an open-drain output that can be used to identify if the P/E/R
controller is currently active. When Ready/Busy is Low, V
operation is in progress. When the operation completes Ready/Busy goes High, V
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.
Refer to the
calculate the value of the pull-up resistor.
During power-up and power-down a minimum recovery time of 10 µs is required before the
command interface is ready to accept a command. During this period the RB signal is Low,
