<Addition>

• 1.5V reference level circuit is a circuit that prepared 1.5V power-supply voltage needed in this LSI to be easily

generable. The power supply of 1.5V is enabled by using recommendation FET shown in Figure 5-1.

* FET Recommended Device No.

* C1 is the capacitor to prevent oscillation.

In the range of operating temperature, make sure to maintain low

ESR and the capacitance recommended value is 10F because

oscillation may occur when the capacitance value changes due to

the change of temperature.

• As for power supply ON, the order of DVDD33 power supply voltage (3.3V) to FET source supply voltage (3.3V) is

recommended.
