Power-up and power-down
At Power-up and Power-down, the device must not be selected (that is Chip Select (S) must
follow the voltage applied on V
Usually a simple pull-up resistor on Chip Select (S) can be used to ensure safe and proper
Power-up and Power-down.
To avoid data corruption and inadvertent write operations during Power-up, a Power On
Reset (POR) circuit is included. The logic inside the device is held reset while V

Moreover, the device ignores all Write Enable (WREN), Page Program (PP), Sector Erase
(SE), Bulk Erase (BE) and Write Status Register (WRSR) instructions until a time delay of
