DDR and DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR SDRAM interface of the
MPC8347EA. 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
MPC8347E PowerQUICC II Pro Integrated Host Processor Hardware
Document,” for silicon revision level determination.

DDR and DDR2 SDRAM DC Electrical Characteristics
Table 12 provides the recommended operating conditions for the DDR2 SDRAM component(s) of the
MPC8347EA when GVDD(typ) = 1.8 V.

Notes:
1. DLL lock times are a function of the ratio between the output clock and the coherency system bus clock (csb_clk). A 2:1 ratio
results in the minimum and an 8:1 ratio results in the maximum.
2. The csb_clk is determined by the CLKIN and system PLL ratio. See Section 19, “Clocking.
