DDR1 and DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR1 and DDR2 SDRAM interface
of the MPC8323E. Note that DDR1 SDRAM is Dn_GVDD(typ) = 2.5 V and DDR2 SDRAM is
Dn_GVDD(typ) = 1.8 V. The AC electrical specifications are the same for DDR1 and DDR2 SDRAM.
6.1
DDR1 and DDR2 SDRAM DC Electrical Characteristics
Table 12 provides the recommended operating conditions for the DDR2 SDRAM component(s) of the
MPC8323E when Dn_GVDD(typ) = 1.8 V.
Table 13 provides the DDR2 capacitance when Dn_GVDD(typ) = 1.8 V.

Notes:
1. D

_GV
DD is expected to be within 50 mV of the DRAM Dn_GVDD at all times.
2. MVREF
nREF 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 MVREF
nREF 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 MVREF
nREF. This rail should track variations in the DC level of MVREFnREF.
4. Output leakage is measured with all outputs disabled, 0 V
≤ VOUT ≤ Dn_GVDD.
