9*, 10* NC - Not used
11 WR Input Write enable: Controls access to command user interface, to data cue register and to address
cue latch. At Low, WR is active to input address and data at leading edge.
12 /RP Input Reset/power-down: By setting /RP at Low, control circuit is initialized when supplying power.
When supplying/breaking power, /RP pin is maintained at Low to protect data.
If /RP is at Low, device is in condition of deep power down.
To return from the deep power down, 480ns is required.
When pin /RP is at Low, all chip operation is interrupted and reset.
After return, device reads array.
13 VPP - Device power supply: 5.0 V
14 /WP - Write/Erase power supply: 5.0±0.5V is applied during the writing/erasing operation.
15 RY/BY Output Ready/Busy: Outputs the condition of the internal write state machine. "Low" shows the write
state machine is in operation. When the machine is waiting for the next instruction to operate,
interrupting erasing, or in deep power-down condition, RY/BY pin is in the float condition.
