DRAM pad specifications

This section specifies the electrical characteristics of the DRAM pads. Please refer to the tables in Section 2.2, Pin descriptions,

for a cross reference between package pins and pad types.

DRAM pads feature list:

•

Driver

— Configurable to support LPDDR half strength, LPDDR full strength, DDR1, DDR2 half strength, DDR2 full

strength, and SDR modes.

— VDD_HV_DRAM range of

– 1.8 V nominal

– 2.5 V nominal

– 3.3 V nominal

•

Receiver

— Differential or pseudo-differential input buffer in all DRAM pads

— All inputs are tolerant up to their VDD_HV_DRAM absolute maximum rating

— Data and strobe pads can be configured to support four signal termination options

– Infinite/no termination

–50

–75

– 150

The electrical data provided in Section 3.19, DRAM pad specifications, applies to the pads listed in Table 43.

All three pad types can be configured to support SDR, DDR, DDR2 half and full strength, and LPDDR half and full strength

modes, according to Table 44.

Normal Operation

1 Normal operation except no drive current and input buffer output is unknown. The pad

pre-drive circuitry will function normally but since VDD_HV_PDI is unpowered the outputs

will not drive high even though the output PMOS can be enabled.
