Instructions for Use:

1. Power Supply:

   • Ensure that the supply voltage (Vcc) is within the range of 3.0V to 3.6V.
   • Connect Vcc to all Vcc pins and GND to all GND pins.

2. Signal Timing:

   • Ensure that the address, data, and control signals meet the specified setup and hold times.
   • The access time (tAA) should be at least 10 ns to ensure reliable operation.

3. Data and Address Lines:

   • Connect the address lines (A0-A19) to the appropriate address inputs.
   • Connect the data lines (DQ0-DQ7) to the appropriate data inputs/outputs.

4. Control Signals:

   • Chip Enable (CE#): Active low. When high, the device is in standby mode.
   • Output Enable (OE#): Active low. When low, the data outputs are enabled.
   • Write Enable (WE#): Active low. When low, the device is in write mode.

5. Write Operation:

   • Set CE# and WE# low.
   • Apply the desired address to the address lines.
   • Apply the data to be written to the data lines.
   • Maintain the required setup and hold times for address and data signals.

6. Read Operation:

   • Set CE# and OE# low.
   • Apply the desired address to the address lines.
   • Maintain the required setup and hold times for the address signals.
   • Data will be available on the data lines after the access time (tAA).

7. Standby Mode:

   • Set CE# high to place the device in standby mode, which reduces power consumption.

8. Handling:

   • Handle the device with care to avoid static damage.
   • Follow proper ESD precautions when handling the device.

9. Storage:

   • Store the device in a dry environment to prevent moisture damage.

10. Mounting:

    • Follow the recommended PCB layout and mounting guidelines to ensure reliable performance.
