Standby supply voltage
1) Total power consumption = IDD
2) A typical design will provide 3.3 V to the I/O supply (i.e., V
2) Pull-up current = 50 µA typical at V
Refer to the strength column in the pin assignment tables for all package types.
Assumes buffer has no pull-up or pull-down resistors.
The leakage value given assumes that the pin is configured as an input pin but is not currently being driven.
compatible with 3.3 V powered external logic (i.e., 3.3 V SDRAMs).
