Power Supply Voltage Specification

Table 3 provides the recommended operating conditions for the device. Note that the values in Table 3 are

the recommended and tested operating conditions. Proper device operation outside of these conditions is

not guaranteed.

Storage temperature range

TSTG

–55 to 150

°C—

Notes:

1 Functional and tested operating conditions are given in Table 3. Absolute maximum ratings are stress ratings only, and

functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause

permanent damage to the device.

2 Caution: MV

IN must not exceed GVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during

power-on reset and power-down sequences.

3 Caution: OV

IN must not exceed OVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during

power-on reset and power-down sequences.

4 (M,O)V

IN and MVREF may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2.

5 OV

IN on the PCI interface may overshoot/undershoot according to the PCI Electrical Specification for 3.3-V operation, as

shown in Figure 2.

6 L[1,2]_nV

DD includes SDAVDD_0, XCOREVDD, and XPADVDD power inputs.
