Instructions for Use

1. Power Supply:

   • Connect Vcc (pin 28) to the power supply (4.5V to 5.5V).
   • Connect Vss (pin 14) to ground.

2. Programming Voltage:

   • Apply 12V to Vpp (pin 24) during programming operations.

3. Addressing:

   • Connect address lines A0-A16 to the desired memory location.
   • Address lines A0-A16 are active low.

4. Data Input/Output:

   • Data is input/output through the D0-D7 pins.
   • Data lines D0-D7 are bidirectional.

5. Control Signals:

   • /CE (Chip Enable): Low to enable the device.
   • /OE (Output Enable): Low to enable data output.
   • /WE (Write Enable): Low to initiate write operations.

6. Programming:

   • Set /CE and /OE low.
   • Apply the desired address to A0-A16.
   • Apply the data to be written to D0-D7.
   • Set /WE low for the duration of the write cycle (3ms).

7. Erasing:

   • Apply 12V to Vpp (pin 24).
   • Set /CE low.
   • Perform a chip erase by setting all address lines to high and holding /WE low for 1 second.

8. Reading:

   • Set /CE and /OE low.
   • Apply the desired address to A0-A16.
   • Data will be available on D0-D7 after the access time (70ns).

9. Standby Mode:

   • Set /CE high to put the device in standby mode, reducing current consumption.

10. Handling Precautions:

    • Handle the device with care to avoid static discharge.
    • Ensure proper heat dissipation during programming and erasing operations.
