VCC1=VCC2=5V
Switching Characteristics
(VCC1 = VCC2 = 5V, VSS = 0V, at Topr =
20 to 85°C / 40 to 85°C unless otherwise specified)
NOTES:
1.
Calculated according to the BCLK frequency as follows:
2.
Calculated according to the BCLK frequency as follows:
n is “2” for 2-wait setting, “3” for 3-wait setting.
3.
Calculated according to the BCLK frequency as follows:
4.
Calculated according to the BCLK frequency as follows:
