MPC8548E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 5

Freescale Semiconductor
Power Characteristics
NOTE
In order to guarantee MCKE low during power-up, the above sequencing for
GVDD is required. If there is no concern about any of the DDR signals being
in an indeterminate state during power-up, then the sequencing for GVDD is
not required.
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.

Notes:
1. CCB frequency is the SoC platform frequency, which corresponds to the DDR data rate.
2. SLEEP is based on VDD = 1.1 V, Tj = 65°C.
3. Typical-65 is based on VDD = 1.1 V, Tj = 65°C, running Dhrystone.
4. Typical-105 is based on VDD = 1.1 V, Tj = 105°C, running Dhrystone.
5. Maximum is based on VDD = 1.1 V, Tj = 105°C, running a smoke test.
Table 5. SYSCLK AC Timing Specifications
At recommended operating conditions (see Table 2) with OVDD = 3.3 V ± 165 mV.
