Power Characteristics
The estimated typical power dissipation, not including I/O supply power, for this family of MPC8313E
devices is shown in this table. Table 5 shows the estimated typical I/O power dissipation.
This table describes a typical scenario where blocks with the stated percentage of utilization and
impedances consume the amount of power described.

Note:
1. The values do not include I/O supply power or AVDD, but do include core, USB PLL, and a portion of SerDes digital power
(not including XCOREVDD, XPADVDD, or SDAVDD, which all have dedicated power supplies for the SerDes PHY).
2. Typical power is based on a voltage of VDD = 1.05 V and an artificial smoker test running at room temperature.
3. Maximum power is based on a voltage of VDD = 1.05 V, a junction temperature of TJ = 105C, and an artificial smoker test.
