Instructions for Use

1. Power Supply:

   • Ensure that the supply voltage (Vcc) is set to 3.3V.
   • Connect the ground (GND) pin to the system ground.

2. Address Lines:

   • Connect the address lines (A0-A16) to the corresponding address lines of the system bus.

3. Data Lines:

   • Connect the data lines (DQ0-DQ7) to the corresponding data lines of the system bus.

4. Control Signals:

   • Chip Select (CS#): Active low. When low, the device is selected.
   • Output Enable (OE#): Active low. When low, the data outputs are enabled.
   • Write Enable (WE#): Active low. When low, a write operation is performed.

5. Timing Considerations:

   • Ensure that the access time (taa) and cycle time (tcyc) are respected to avoid data corruption.
   • The output enable delay (OE to Data Valid) should be considered when reading data.

6. Power-Up and Power-Down:

   • During power-up, ensure that the supply voltage rises to 3.3V before applying any control signals.
   • During power-down, allow the supply voltage to fall to 0V before removing control signals.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the sensitive components.
   • Store the device in an anti-static bag when not in use.

8. Environmental Conditions:

   • Operate the device within the specified temperature range (-40掳C to +85掳C) to ensure reliable performance.

9. Mounting:

   • Mount the device on a PCB with appropriate thermal management to ensure it operates within the specified temperature range.

10. Testing:

    • Test the device using standard SRAM test patterns to verify proper functionality.
