Electrical Characteristics
Table 1–6 lists supply current specifications for V_{CC_CLKIN} and V_CCPGM. Use the
PowerPlay EPE to get supply current estimates for the remaining power supplies.

Notes to Table 1–7:
(1) This value is specified for normal device operation. The value may vary during power up. This applies for all V_CCIO
settings (3.0, 2.5, 1.8, 1.5, and 1.2 V).
(2) The 10 mA I/O leakage current limit is applicable when the internal clamping diode is off. A higher current is
observed when the diode is on.
OCT Specifications
If OCT calibration is enabled, calibration is automatically performed at power up for
I/Os connected to the calibration block. Table 1–8 lists the HardCopy IV OCT
calibration block accuracy specifications.
