Electrical Characteristics
Figure 2 shows the undershoot and overshoot voltages at the interfaces of the MPC8572E.
Figure 2. 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.

VIL
Note:
For I2C and JTAG, tCLOCK references SYSCLK.
For DDR, tCLOCK references MCLK.
For eTSEC, tCLOCK references EC_GTX_CLK125.
For eLBC, tCLOCK references LCLK.
