VCC1=VCC2=3V
Timing Requirements
(V
CC1 = 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 V
CC1 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.
