Electrical Characteristics
Table 1–4 lists supply current specifications for V_{CC_CLKIN} and V_CCPGM. Use the EPE to get
supply current estimates for the remaining power supplies.

Notes To Table 1–5:
(1) This value is specified for normal device operation. The value may vary during power up. This applies for all VCCIO
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.
On-Chip Termination (OCT) Specifications
If OCT calibration is enabled, calibration is automatically performed at power up for
I/Os connected to the calibration block. Table 1–6 lists the HardCopy III OCT
calibration block accuracy specifications.
