Overshoot/Undershoot Voltage for TVDD/BVDD/GVDD/LVDD/OVDD The core voltage must always be provided at nominal 1.1 V. (See Table 2 for actual recommended core voltage). Voltage to the processor interface I/Os are provided through separate sets of supply pins and must be provided at the voltages shown in Table 2. The input voltage threshold scales with respect to the associated I/O supply voltage. TVDD, BVDD, OVDD and LVDD based receivers are simple CMOS I/O circuits and satisfy appropriate LVCMOS type specifications. The DDR2 and DDR3 SDRAM interface uses differential receivers referenced by the externally supplied MVREFn signal (nominally set to GVDD/2) as is appropriate for the SSTL_1.8 electrical signaling standard for DDR2 or 1.5-V electrical signaling for DDR3. The DDR DQS receivers cannot be operated in single-ended fashion. The complement signal must be properly driven and cannot be grounded.

The drive strength of the local bus interface is determined by the configuration of the appropriate bits in PORIMPSCR. 2. The drive strength of the DDR2 or DDR3 interface in half-strength mode is at Tj = 105°C and at GVDD (min). 2.2 Power Sequencing The MPC8572E requires its power rails to be applied in a specific sequence to ensure proper device operation. These requirements are as follows for power up: 1. VDD, AVDD_n, BVDD, LVDD, OVDD, SVDD_SRDS1 and SVDD_SRDS2, TVDD, XVDD_SRDS1 and XVDD_SRDS2 2. GVDD All supplies must be at their stable values within 50 ms. Items on the same line have no ordering requirement with respect to one another. Items on separate lines must be ordered sequentially such that voltage rails on a previous step must reach 90% of their value before the voltage rails on the current step reach 10% of theirs. To guarantee MCKE low during power-on reset, 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-on reset, then the sequencing for GVDD is not required. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 14 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-on reset, and extra current may be drawn by the device. 3 Power Characteristics Table 4.

Notes: This reflects the MPC8572E power dissipation excluding the power dissipation from B/G/L/O/T/XVDD rails. Typical-65 is based on VDD = 1.1 V, Tj = 65 ° C, running Dhrystone. 3 Typical-105 is based on V DD = 1.1 V, T j = 105 ° C, running Dhrystone. 4 Maximum is based on VDD = 1.1 V, Tj = 105 °C, running a smoke test. 2 1 4 4.1 Input Clocks System Clock Timing Table 5.

Caution: The CCB clock to SYSCLK ratio and e500 core to CCB clock ratio settings must be chosen such that the resulting SYSCLK frequency, e500 (core) frequency, and CCB clock frequency do not exceed their respective maximum or minimum operating frequencies.Refer to Section 19.2, “CCB/SYSCLK PLL Ratio,” and Section 19.3, “e500 Core PLL Ratio,” for ratio settings. 2. Rise and fall times for SYSCLK are measured at 0.6 V and 2.7 V. 3. Timing is guaranteed by design and characterization. 4. This represents the total input jitter—short term and long term—and is guaranteed by design. 5. The SYSCLK driver’s closed loop jitter bandwidth should be
