VCC1=VCC2=3V

Timing Requirements

(VCC1 = VCC2 = 3V, VSS = 0V, at Topr =

−20 to 85°C / −40 to 85°C unless otherwise specified)

NOTES:

1. The condition is VCC1=VCC2=2.7 to 3.0V.

2. Calculated according to the VCC1 voltage as follows:

[ns]

3. Calculated according to the VCC1 voltage as follows:

[ns]

4. Calculated according to the VCC1 voltage as follows:

[ns]

NOTES:

1. Calculated according to the BCLK frequency as follows:

2. Calculated according to the BCLK frequency as follows:

n is ”2” for 1-wait setting, “3” for 2-wait setting and “4” for 3-wait setting.

3. Calculated according to the BCLK frequency as follows:

n is “2” for 2-wait setting, “3” for 3-wait setting.
