Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the range of 1.65V to 1.95V.
    • Connect the VCC pin to a stable power source.
  2. Standby Mode:

    • To enter standby mode, set the Chip Select (CS) pin to a high state.
    • The standby current (ICCSTBY) should be less than or equal to 0.5 μA.
  3. Active Mode:

    • To activate the device, set the CS pin to a low state.
    • The active current (ICCACT) during continuous read operations should be less than or equal to 10 mA.
  4. Timing Parameters:

    • The access time (tAA) and cycle time (tCYC) are both 70 ns when VCC is 1.8V and the load capacitance (CL) is 50 pF.
  5. Output Levels:

    • The output high voltage (VOH) should be between 1.6V and 1.8V when the output current (IO) is -0.4 mA.
    • The output low voltage (VOL) should be between 0V and 0.2V when the output current (IO) is 0.4 mA.
  6. Input Levels:

    • The input low voltage (VIL) should be between 0V and 0.8V.
    • The input high voltage (VIH) should be between 1.0V and 1.8V.
  7. Handling:

    • Handle the device with care to avoid static damage.
    • Store the device in a dry, cool place to prevent moisture damage.
  8. Mounting:

    • Follow the recommended soldering profile to ensure proper bonding and avoid thermal stress.
    • Ensure that all pins are correctly aligned before soldering.
