Power Characteristics

and VDDC) before the I/O voltage (GVDD, LVDD, and OVDD) and assert PORESET before the power

supplies fully ramp up. In the case where the core voltage is applied first, the core voltage supply must rise

to 90% of its nominal value before the I/O supplies reach 0.7 V; see Figure 3. Once both the power supplies

(I/O voltage and core voltage) are stable, wait for a minimum of 32 clock cycles before negating

PORESET.

Note that there is no specific power down sequence requirement for the MPC8313E. I/O voltage supplies

(GVDD, LVDD, and OVDD) do not have any ordering requirements with respect to one another.

Power Characteristics

The estimated typical power dissipation, not including I/O supply power, for this family of MPC8313E

devices is shown in Table 4. Table 5 shows the estimated typical I/O power dissipation.

1 The values do not include I/O supply power or AV

DD, 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).
