Notes:
1
These are the recommended and tested operating conditions. Proper device
operation outside of these conditions is not guaranteed.
2
PCI pins are designed to withstand LVdd + 0.5 V dc when LVdd is connected
to a 5.0V dc power supply.
3
PCI pins are designed to withstand LVdd + 0.5 V dc when LVdd is connected
to a 3.3 V dc power supply.
4
CPU speed limited to 266 MHz and 300 MHz operation at this voltage. See
Cautions:
5
Input voltage (VIN) must not be greater than the supply voltage
(Vdd/AVdd/AVdd2) by more than 2.5 V at all times including during power-on
reset. Input voltage (VIN) must not be greater than GVdd/OVdd by more than
0.6 V at all times including during power-on reset.
6
OVdd must not exceed Vdd/AVdd/AVdd2 by more than 1.8 V at any time
including during power-on reset.
7
Vdd/AVdd/AVdd2 must not exceed OVdd by more than 0.6 V at any time
including during power-on reset.
8
GVdd must not exceed Vdd/AVdd/AVdd2 by more than 1.8 V at any time
including during power-on reset.
9
LVdd must not exceed Vdd/AVdd/AVdd2 by more than 5.4 V at any time
including during power-on reset.
10 LVdd must not exceed OVdd by more than 3.0 V at any time including during
power-on reset.
