Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the specified range of 2.7V to 3.6V.
   • Connect the ground (GND) pin to a stable ground reference.

2. Chip Enable (CE):

   • The CE pin must be low to enable the device.
   • Ensure the setup and hold times for CE are met as specified in the table.

3. Output Enable (OE):

   • The OE pin must be low to enable data output.
   • Ensure the setup and hold times for OE are met as specified in the table.

4. Address Lines:

   • Apply the desired address to the address lines (A0-A18).
   • Ensure the address setup and hold times are met as specified in the table.

5. Data Lines:

   • Data will be available on the data lines (DQ0-DQ7) after the access time (t_ACC).

6. Write Operations:

   • To perform a write operation, ensure the write enable (WE) pin is low.
   • Follow the write cycle time (t_WC) for successful data programming.

7. Block Erase:

   • To perform a block erase, use the appropriate command sequence.
   • Follow the block erase time (t_BE) for successful erasure.

8. Standby Mode:

   • To enter standby mode, set CE high.
   • Monitor the standby current (I_CC(STBY)) to ensure it is within the specified range.

9. Timing Considerations:

   • All timing parameters must be adhered to for reliable operation.
   • Use a stable clock source and ensure all setup and hold times are met.

10. Handling:

    • Handle the device with care to avoid static discharge.
    • Store the device in a dry environment to prevent moisture damage.
