DATA SHEET

512MB Registered DDR2 SDRAM DIMM

EBE51AD8AJFA (64M words × 72 bits, 1 Rank)

Specifications

Features

• Density: 512MB

• Double-data-rate architecture; two data transfers per

clock cycle

• Organization

• The high-speed data transfer is realized by the 4 bits

prefetch pipelined architecture

64M words × 72 bits, 1 rank

• Mounting 9 pieces of 512M bits DDR2 SDRAM

sealed in FBGA

• Bi-directional differential data strobe (DQS and /DQS)

is transmitted/received with data for capturing data at

the receiver

• Package: 240-pin socket type dual in line memory

module (DIMM)

• DQS is edge-aligned with data for READs; center-

aligned with data for WRITEs

PCB height: 30.0mm

Lead pitch: 1.0mm

• Differential clock inputs (CK and /CK)

Lead-free (RoHS compliant)

• Power supply: VDD = 1.8V ± 0.1V

• Data rate: 667Mbps (max.)

• DLL aligns DQ and DQS transitions with CK

transitions

• Commands entered on each positive CK edge; data

and data mask referenced to both edges of DQS

• Four internal banks for concurrent operation

(components)

• Data mask (DM) for write data

• Interface: SSTL_18

• Posted /CAS by programmable additive latency for

better command and data bus efficiency

• Burst lengths (BL): 4, 8

• /CAS Latency (CL): 3, 4, 5

• Off-Chip-Driver Impedance Adjustment and On-Die-

Termination for better signal quality

• Precharge: auto precharge option for each burst

• /DQS can be disabled for single-ended Data Strobe

access

operation

• Refresh: auto-refresh, self-refresh

• Refresh cycles: 8192 cycles/64ms

• 1 piece of PLL clock driver, 1 piece of register driver

and 1 piece of serial EEPROM (2K bits EEPROM) for

Presence Detect (PD)

Average refresh period

7.8µs at 0°C ≤ TC ≤ +85°C

3.9µs at +85°C < TC ≤ +95°C

• Operating case temperature range

TC = 0°C to +95°C
