MPC8240 Part Number Specification for the XPC8240RXXnnnx Series
3
General Parameters
1.4.1.5 Power Characteristics
Table 5 provides power consumption data for the MPC8240. Power consumption on the PLL supply pins (AVDD and AVDD2) and the DLL supply pin (LAVDD) less than 15 mW. This parameter is guaranteed by design and is not
tested.
Die-junction temperature

0 to 105
°C
Notes:
1. These are the recommended and tested operating conditions. Proper device operation outside of these conditions
is not guaranteed.
2. These signals are designed to withstand LVDD + 0.5 V DC when LVDD is connected to a 3.3- or 5.0-V DC power
supply.
3. LVDD input tolerant signals: PCI interface, EPIC control, and OSC_IN signals.
Cautions:
5. Input voltage (Vin) must not be greater than the supply voltage (VDD/AVDD/AVDD2/LAVDD) by more than 2.5 V at all
times, including during power-on reset.
6. OVDD must not exceed VDD/AVDD/AVDD2/LAVDD by more than 1.8 V at any time, including during power-on reset.
This limit may be exceeded for a maximum of 20 ms during power-on reset and power-down sequences.
7. VDD/AVDD/AVDD2/LAVDD must not exceed OVDD by more than 0.6 V at any time, including during power-on reset.
This limit may be exceeded for a maximum of 20 ms during power-on reset and power-down sequences.
8. GVDD must not exceed VDD/AVDD/AVDD2/LAVDD by more than 1.8 V at any time, including during power-on reset.
This limit may be exceeded for a maximum of 20 ms during power-on reset and power-down sequences.
9. LVDD must not exceed VDD/AVDD/AVDD2/LAVDD by more than 5.4 V at any time, including during power-on reset.
This limit may be exceeded for a maximum of 20 ms during power-on reset and power-down sequences.
10.LVDD must not exceed OVDD by more than 3.6 V at any time, including during power-on reset. This limit may be
exceeded for a maximum of 20 ms during power-on reset and power-down sequences.
