Notes:

1. IDC1 includes VCC, VPUMP, and VCCI, currents. Values do not include I/O static contribution, which is shown in

Table 3-9 on page 3-11 and Table 3-10 on page 3-13.

2. IDC2 represents the current from the VCC33A and VCCI supplies when the RTC (and the 32 kHz crystal

oscillator) is ON, the FPGA is OFF, and the voltage regulator is OFF.

3. IDC3 represents the current from the VCC33A and VCCI supplies when the RTC (and the crystal oscillator), the

FPGA, and the voltage regulator are OFF.

4. VCCI supply is ON, since the east and west I/O banks are not cold-sparable. Values do not include I/O static

contribution, which is shown in Table 3-9 on page 3-11 and Table 3-10 on page 3-13.
