Features Description

240-pin JEDEC-compliant DIMM, 133.35 mm wide by

30 mm high

Operating Voltage: 1.8 V ±0.1

I/O Type: SSTL_18

Data Transfer Rate: 6.4 Gigabytes/sec

Bursts Length: 4 and 8

Programmable I/O driver strength (OCD)

Programmable On-Die Termination (ODT)

Programmable CAS Latency: 4 or 5

Differential/Redundant Data Strobe signals

DTM63368 is an Unbuffered ECC 256Mx72

memory module, which conforms to JEDEC's

DDR2, PC2-6400 standard. The assembly is

consisting two Ranks. Each Rank is comprised of

nine 128Mx8 DDR2 SDRAMs. One 2K-bit

EEPROM is used for Serial Presence Detect.

Both output driver strength and input termination

impedance are programmable to maintain signal

integrity on the I/O signals.

Fully ROHS Compliant
