Instructions for Use:

1. Power Supply:

   • Connect Vcc to the power supply within the range of 2.7 V to 5.5 V.
   • Connect Vss to ground.

2. Programming:

   • Apply the programming voltage (Vpp) to the appropriate pin (usually Pin 28).
   • Use a programmer that supports the AT27C4096-12JC to write data to the device.
   • Ensure the programming time per byte is approximately 2 ms.

3. Erasing:

   • To erase the entire chip, apply the programming voltage (Vpp) to the appropriate pin.
   • The typical erase time is 5 seconds.

4. Reading:

   • Apply the appropriate address to the address lines (A0-A18).
   • The data will be available on the data lines (D0-D7) after the access time (120 ns).

5. Temperature Considerations:

   • Ensure the operating temperature is within the range of -40°C to +85°C.
   • Store the device in a temperature range of -65°C to +150°C.

6. Handling:

   • Handle the device with care to avoid damage from static electricity.
   • Follow standard ESD (Electrostatic Discharge) precautions.

7. Mounting:

   • Ensure proper soldering and mounting techniques to prevent mechanical stress on the package.
   • Verify the correct orientation of the device during installation.

8. Testing:

   • After programming and installation, test the device to ensure it functions correctly.
   • Use a memory tester or a custom test program to verify data integrity.
