Features
Description
240-pin JEDEC-compliant DIMM, 133.35 mm wide by
30 mm high
Operating Voltage: 1.8 V ±0.1
DTM63372 is an Unbuffered non-ECC 128Mx64
memory module, which conforms to JEDEC's
DDR2, PC2-5300 standard. The assembly is
comprised of one Rank of eight 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.
I/O Type: SSTL_18
Data Transfer Rate: 5.3 Gigabytes/sec
Data Bursts: 4 or 8 bits, Sequential or Interleaved ordering
Programmable I/O driver strength (OCD)
Programmable On-Die Termination (ODT)
Programmable CAS Latency: 4 or 5
Differential/Redundant Data Strobe signals
SDRAM Addressing (Row/Col/Bank): 14/10/3
Fully ROHS Compliant

These values are guaranteed by design and are tested on a sample basis only
DQx and ODT are disabled, and 0 V ≤ VOUT ≤ VDD.
VDD = 1.7 V, VOUT = 1420 mV. (VOUT - VDD)/IOH must be less than 21 Ohms for values of VOUT between VDD and (VDD - 280
mV).
VDD = 1.7 V, VOUT = 280 mV. VOUT/IOL must be less than 21 Ohms for values of VOUT between 0 V and 280 mV.
