Instructions for Use:

1. Power Supply:

   • Connect Vcc to pins 27 and 1.
   • Connect ground (GND) to pin 14.

2. Programming:

   • Apply 12.0V ± 0.5V to Vpp (pin 28).
   • Apply 5V to Vcc (pins 27 and 1).
   • Use a programmer that supports the M27C512-15F1 to write data to the device.
   • Ensure the programming current does not exceed 25 mA.

3. Erase:

   • Expose the device to ultraviolet light through the window on the top of the package for at least 20 minutes to erase the contents.

4. Reading:

   • Apply 5V to Vcc (pins 27 and 1).
   • Ground all address lines (A0-A18) to read the first byte.
   • Apply the appropriate address to the address lines to read other bytes.
   • The data will be available on the data output lines (D0-D7).

5. Handling:

   • Handle the device with care to avoid static damage.
   • Store the device in a dry, cool place when not in use.
   • Ensure the device is properly grounded to prevent electrostatic discharge.
