Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 1.7V to 3.6V.
   • Connect the VCC pin to the power supply and GND pin to ground.

2. Data Communication:

   • The FM25V02A-GTR supports SPI communication.
   • Connect the SCK (Serial Clock), MOSI (Master Out Slave In), MISO (Master In Slave Out), and CS (Chip Select) pins to the corresponding SPI lines on your microcontroller or system.

3. Initialization:

   • Before performing any read or write operations, ensure the device is properly initialized by setting the CS pin low to select the device.
   • After initialization, set the CS pin high to deselect the device.

4. Read Operation:

   • To read data from the FRAM, send the Read command (0x03) followed by the starting address.
   • The device will then output the data at the specified address.

5. Write Operation:

   • To write data to the FRAM, send the Write command (0x02) followed by the starting address and the data to be written.
   • The device will store the data at the specified address.

6. Data Retention:

   • The device retains data for a minimum of 10 years under normal operating conditions.

7. Endurance:

   • The device can withstand up to 10^14 write cycles without failure.

8. Current Consumption:

   • Monitor the standby current (1.0 μA max) and active current (3.0 mA max) to ensure efficient power management.

9. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to +85°C to avoid damage and ensure reliable performance.

10. Handling Precautions:

    • Handle the device with care to avoid static discharge, which can damage the internal circuitry.
    • Follow standard ESD (Electrostatic Discharge) precautions when handling and storing the device.
