Instructions for Use:

1. Power Supply:

   • Connect Vcc to a stable 5V supply.
   • Connect Vpp to 12V during programming and 5V during normal operation.

2. Addressing:

   • Apply the desired address to the A0-A16 pins to select the memory location.

3. Data Input/Output:

   • During read operations, data is output on the D0-D7 pins.
   • During write operations, data is input on the D0-D7 pins.

4. Control Signals:

   • Chip Select (CS): Low to enable the device.
   • Output Enable (OE): Low to enable data output.
   • Write Enable (WE): Low to initiate a write cycle.
   • Program Enable (PGM): Low to enter programming mode.

5. Programming:

   • Set CS, OE, and WE low.
   • Set PGM low and apply 12V to Vpp.
   • Apply the address and data to be programmed.
   • Hold WE low for the required write cycle time (4 ms typical, 10 ms maximum).

6. Erasing:

   • Set CS, OE, and WE high.
   • Set PGM low and apply 12V to Vpp.
   • Hold PGM low for the required erase cycle time (5 seconds typical, 10 seconds maximum).

7. Reading:

   • Set CS and OE low.
   • Apply the desired address.
   • Data will appear on the D0-D7 pins after the access time (70 ns maximum).

8. Power Down:

   • Ensure Vcc is removed before disconnecting Vpp to avoid damage.

9. Handling:

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