Freescale Semiconductor
Power Characteristics
NOTE
From a system standpoint, if any of the I/O power supplies ramp prior to the
VDD core supply, the I/Os associated with that I/O supply may drive a logic
one or zero during power-up, and extra current may be drawn by the device.

Power Characteristics
The estimated typical power dissipation for the core complex bus (CCB) versus the core frequency for this
family of PowerQUICC III devices is shown in Table 4.
