Instructions for Use

1. Power Supply:

   • Ensure that the supply voltage (Vcc) is within the specified range of 2.7V to 3.6V.
   • The programming voltage (Vpp) must be 12.5V ± 0.5V for write operations.

2. Temperature:

   • Operate the device within the industrial temperature range of -40°C to +85°C.

3. Pin Configuration:

   • Refer to the pin configuration diagram provided in the datasheet to ensure correct connections.
   • Connect Vcc to the appropriate power supply and Vss to ground.
   • Apply Vpp to the designated pin during write operations.

4. Read Operation:

   • To read data, apply the address to the address lines and enable the output by setting the chip select (CS) and output enable (OE) pins low.
   • Data will be available on the data lines after the access time.

5. Write Operation:

   • To write data, set the chip select (CS), output enable (OE), and write enable (WE) pins low.
   • Apply the address and data to the respective lines and provide the programming voltage (Vpp).
   • Wait for the write cycle time to complete before performing another operation.

6. Standby Mode:

   • To minimize power consumption, set the chip select (CS) and output enable (OE) pins high when the device is not in use.

7. Handling:

   • Handle the device with care to avoid static damage.
   • Follow proper handling and storage guidelines to ensure long-term reliability.

For detailed specifications and additional information, refer to the official datasheet provided by Atmel (now part of Microchip Technology).
