Instructions for Use:

1. Power Supply Connection:

   • Connect the supply voltage (VCC) within the operating voltage range of 2.7V to 3.6V.
   • Ensure GND is properly grounded.

2. Signal Timing:

   • Adhere to the specified timing parameters for address setup, hold times, and enable signals to ensure reliable data read/write operations.

3. Write Operations:

   • For writing data, set the Write Enable (WE#) signal low after setting the address and data lines.
   • Maintain the WE# signal low for at least the specified Write Enable Low Time.
   • Allow sufficient Write Cycle Time before initiating another write operation.

4. Read Operations:

   • Set the Chip Enable (CE#) and Output Enable (OE#) signals low to initiate a read.
   • Ensure the address lines are stable before CE# goes low.
   • Maintain OE# low for at least the Output Enable Low Time.

5. Power-down Mode:

   • Enter power-down mode by setting CE#, OE#, and WE# high simultaneously.
   • Exit power-down mode by bringing CE# low.

6. Handling:

   • Handle with care to avoid electrostatic discharge (ESD).
   • Follow proper storage and handling guidelines as per manufacturer recommendations.

Note: Always refer to the specific datasheet provided by the manufacturer for detailed specifications and application notes.
