Instructions for Use:

1. Power Supply: Ensure the operating voltage is within the specified range of 4.5V to 5.5V.
2. Address and Data Lines: Connect address lines (A0-A16) and data lines (D0-D7) as per your system requirements.
3. Control Signals: Properly connect control signals such as Chip Select (CS), Output Enable (OE), and Write Enable (WE).
4. Timing Requirements: Adhere to the specified access times and clock cycle times to ensure reliable operation.
5. Environmental Conditions: Operate within the recommended temperature range to avoid damage or data corruption.
6. Handling Precautions: Handle with care to prevent electrostatic discharge (ESD) damage; use proper ESD protection measures.
7. Mounting Orientation: Ensure correct orientation during PCB assembly to avoid short circuits or incorrect connections.
