Power Characteristics
The I/O power supply ramp-up slew rate should be slower than 4V/100 s, this requirement is for ESD
circuit. Note that there is no specific power down sequence requirement for the device. I/O voltage
supplies (GVDD, LVDD, and NVDD) 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 the device is shown in this
table. Table 5 shows the estimated typical I/O power dissipation.
Table 4. MPC8308 Power Dissipation1
1 The values do not include I/O supply power but do include core (V
DD) and PLL (AVDD1,
AVDD2, XCOREVDD, XPADVDD, and SDAVDD)
Core Frequency (MHz)
CSB Frequency (MHz)
Typical2
2 Typical power is based on best process, a voltage of V
DD = 1.0 V and ambient temperature
of TA = 25 C and an artificial smoker test.
Maximum 3
3 Maximum power is estimated based on best process, a voltage of V
DD = 1.05 V, a junction
temperature of TJ = 105 C
