Instructions for Use

1. Power Supply Connection:

   • Connect Vcc to the power supply (2.7 V to 3.6 V).
   • Connect GND to the ground.
   • For programming, connect Vpp to 12.0 V ± 0.5 V.

2. Address and Data Lines:

   • Connect A0 to A19 to the address lines of your system.
   • Connect DQ0 to DQ7 to the data lines of your system.

3. Control Signals:

   • CE# (Chip Enable): Active low. When low, the device is selected.
   • OE# (Output Enable): Active low. When low, the data output is enabled.
   • WE# (Write Enable): Active low. Used for write operations.

4. Write Protection:

   • The device has hardware write protection. Ensure that the write protection pin is configured correctly to prevent accidental writes.

5. Programming and Erasing:

   • Use the appropriate commands to program and erase the memory. Refer to the datasheet for specific command sequences and timing requirements.

6. Data Retention:

   • Ensure that the device is stored and operated within the specified temperature range to maintain data retention for at least 10 years.

7. Handling Precautions:

   • Handle the device with care to avoid static damage.
   • Follow proper soldering techniques to ensure reliable connections.

For detailed information, refer to the official datasheet provided by STMicroelectronics.
