Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 1.8V to 5.5V.
   • The device operates at a standby current of 1μA and an active current of up to 3mA.

2. Communication:

   • The 24LC65-I/P uses the I₂C interface for communication.
   • The I₂C bus requires pull-up resistors on both SDA and SCL lines.
   • The typical operating frequency is 100 kHz, but it can support up to 400 kHz.

3. Write Operations:

   • A write cycle takes approximately 5ms.
   • For page writes (up to 64 bytes), the time is also around 5ms.
   • Ensure no other operations are initiated during the write cycle to avoid data corruption.

4. Read Operations:

   • Read operations are much faster and do not have the same timing constraints as write operations.

5. Data Retention:

   • The device retains data for at least 100 years under standard conditions (25°C, 5V).

6. Temperature Considerations:

   • The operating temperature range is from -40°C to 85°C.
   • The storage temperature range is from -65°C to 150°C.

7. Memory Organization:

   • The memory is organized into 256 pages, each containing 64 bytes.
   • The total memory capacity is 65 Kbits (8K x 8 bits).

8. Handling:

   • Handle the device with care to avoid static damage.
   • Follow proper ESD (Electrostatic Discharge) precautions when handling the device.

9. Package:

   • The 24LC65-I/P is available in an 8-pin PDIP package.

10. Application Notes:

    • Refer to the datasheet for detailed application notes and specific timing diagrams.
    • Ensure that the device is properly decoupled with a 0.1μF capacitor placed close to the V_CC and GND pins.

By following these guidelines, you can ensure reliable operation of the 24LC65-I/P EEPROM.
