DATA SHEET

4GB Registered DDR3 SDRAM DIMM

EBJ41HE4BDFA (512M words × 72 bits, 2 Ranks)

Specifications

Features

• Density: 4GB

• Organization

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

clock cycle

• The high-speed data transfer is realized by the 8 bits

512M words × 72 bits, 2 ranks

prefetch pipelined architecture

• Mounting 36 pieces of 1G bits DDR3 SDRAM sealed

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

is transmitted/received with data for capturing data at

the receiver

in FBGA

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

module (DIMM)

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

PCB height: 30.5mm (max.)

Lead pitch: 1.0mm

Lead-free (RoHS compliant) and Halogen-free

• Power supply: VDD = 1.5V ± 0.075V

• Data rate: 1333Mbps/1066Mbps (max.)

aligned with data for WRITEs

• Differential clock inputs (CK and /CK)

• 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

• Eight internal banks for concurrent operation

(components)

• Posted /CAS by programmable additive latency for

better command and data bus efficiency

• Interface: SSTL_15

• On-Die-Termination (ODT) for better signal quality

Synchronous ODT

• Burst lengths (BL): 8 and 4 with Burst Chop (BC)

• /CAS Latency (CL): 6, 7, 8, 9

Dynamic ODT

• /CAS write latency (CWL): 5, 6, 7

Asynchronous ODT

• Precharge: auto precharge option for each burst

access

• Multi Purpose Register (MPR) for temperature read

out

• Refresh: auto-refresh, self-refresh

• Refresh cycles

• ZQ calibration for DQ drive and ODT

• Programmable Partial Array Self-Refresh (PASR)

Average refresh period

7.8µs at 0°C ≤ TC ≤ +85°C

3.9µs at +85°C < TC ≤ +95°C

• /RESET pin for Power-up sequence and reset

function

• Operating case temperature range

TC = 0°C to +95°C

• SRT range:

Normal/extended

• Programmable Output driver impedance control

• 1 piece of registering clock driver and 1 piece of

serial EEPROM (256 bytes EEPROM) for Presence

Detect (PD)

• Class B temperature sensor functionality with

EEPROM

Note: Warranty void if removed DIMM heat

spreader.
