Instructions for Use:

1. Power Supply:

   • Ensure that the supply voltage (Vcc) is within the specified range of 2.5V to 5.5V.
   • Connect the ground (GND) pin to the system ground.

2. Addressing:

   • The device has 15 address lines (A0 to A14) for accessing the 32K memory locations.
   • Address lines should be connected to the appropriate system address lines.

3. Data Input/Output:

   • The data input/output (I/O) lines (D0 to D7) are bidirectional and should be connected to the system data bus.
   • Use the chip select (CS) line to enable or disable the device. When CS is low, the device is active; when high, it is inactive.

4. Control Signals:

   • Write Enable (WE): Low to initiate a write operation.
   • Output Enable (OE): Low to enable data output.
   • Write Protect (WP): High to prevent accidental writes. Set low to allow writes.

5. Write Operation:

   • To write data, set CS and WE low, and provide the address and data on the I/O lines.
   • Wait for the write cycle time (5ms) before performing another operation.

6. Read Operation:

   • To read data, set CS and OE low, and provide the address on the address lines.
   • Data will be available on the I/O lines after the access time (55ns).

7. Standby Mode:

   • To reduce power consumption, set CS high to put the device in standby mode.

8. Handling Precautions:

   • Handle the device with care to avoid static damage.
   • Ensure proper grounding and use anti-static wrist straps if necessary.

9. Storage:

   • Store the device in a dry, cool place to ensure long-term reliability.

10. Environmental Considerations:

    • Operate the device within the specified temperature range to avoid damage and ensure reliable performance.
