Instructions

1. Power Supply:

   • Connect Vcc to a stable 5V supply.
   • Ground all GND pins.

2. Addressing:

   • Apply the desired address to the A0-A7 address lines.
   • Ensure that the address lines are stable before initiating a read or write operation.

3. Data I/O:

   • Data is read from or written to the D0-D7 data lines.
   • For reading, ensure the output enable (OE) pin is low.
   • For writing, ensure the chip enable (CE) and write enable (WE) pins are low.

4. Programming:

   • Apply 12.5V 卤 0.5V to the Vpp pin during programming.
   • Ensure the CE and WE pins are low.
   • Apply the desired data to the D0-D7 lines and the address to the A0-A7 lines.
   • Hold the programming voltage for the required duration.

5. Erasing:

   • Expose the device to UV light (253.7nm wavelength) for at least 15 minutes to erase the memory.
   • Cover the window with an opaque label after erasure to prevent accidental exposure.

6. Handling:

   • Handle the device with care to avoid static discharge.
   • Store the device in a dry environment to prevent moisture damage.

7. Testing:

   • After programming, verify the data by reading it back from the memory.
   • Ensure all connections are secure and correct before testing.

8. Storage:

   • Store the device in a cool, dry place when not in use.
   • Keep the device away from strong magnetic fields and direct sunlight.
