DDR and DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR SDRAM interface of the
MPC8640. Note that DDR SDRAM is Dn_GVDD(typ) = 2.5 V and DDR2 SDRAM is
Dn_GVDD(typ) = 1.8 V.
6.1
DDR SDRAM DC Electrical Characteristics
Table 13 provides the recommended operating conditions for the DDR2 SDRAM component(s) of the
MPC8640 when Dn_GVDD(typ) = 1.8 V.
Table 14 provides the DDR2 capacitance when Dn_GVDD(typ) =1.8 V.

Notes:
1. D
n_GVDD is expected to be within 50 mV of the DRAM Dn_GVDD at all times.
2. D
n_MVREF is expected to be equal to 0.5 × Dn_GVDD, and to track Dn_GVDD DC variations as measured at the receiver.
Peak-to-peak noise on D
n_MVREF may not 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 be
equal to D
n_MVREF. This rail should track variations in the DC level of Dn_MVREF.
4. Output leakage is measured with all outputs disabled, 0 V
≤ VOUT ≤ Dn_GVDD.
