DDR and DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR SDRAM interface of the
MPC8349EA. Note that DDR SDRAM is GVDD(typ) = 2.5 V and DDR2 SDRAM is GVDD(typ) = 1.8 V.
The AC electrical specifications are the same for DDR and DRR2 SDRAM.
NOTE
The information in this document is accurate for revision 3.0 silicon and later. For
information on revision 1.1 silicon and earlier versions see the MPC8349E
PowerQUICC II Pro Integrated Host Processor Hardware Specifications. See
Section 23.1, “Part Numbers Fully Addressed by this Document,” for silicon revision level
determination.

DDR and DDR2 SDRAM DC Electrical Characteristics
Table 11 provides the recommended operating conditions for the DDR2 SDRAM component(s) of the
MPC8349EA when GVDD(typ) = 1.8 V.

Notes:
1. GVDD is expected to be within 50 mV of the DRAM GVDD at all times.
2. MVREF is expected to equal 0.5 × GVDD, and to track GVDD DC variations as measured at the receiver. Peak-to-peak noise
on MVREF cannot exceed ±2% of the DC value.
3. VTT is not applied directly to the device. It is the supply to which far end signal termination is made and is expected to equal
MVREF. This rail should track variations in the DC level of MVREF.
4. Output leakage is measured with all outputs disabled, 0 V

OUT ≤ GVDD.
