COVER

PRELIMINARY DATA SHEET

4G bits DDR3 SDRAM

EDJ4204BFBG (1024M words × 4 bits)

EDJ4208BFBG (512M words × 8 bits)

EDJ4216BFBG (256M words × 16 bits)

Specifications

Features

• Density: 4G bits

• Organization

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

clock cycle

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

prefetch pipelined architecture

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

is transmitted/received with data for capturing data at

the receiver

— 128M words × 4 bits × 8 banks (EDJ4204BFBG)

— 64M words × 8 bits × 8 banks (EDJ4208BFBG)

— 32M words × 16 bits × 8 banks (EDJ4216BFBG)

• Package

— 78-ball FBGA (EDJ4204BFBG, EDJ4208BFBG)

— 96-ball FBGA (EDJ4216BFBG)

— Lead-free (RoHS compliant) and Halogen-free

• Power supply: VDD = 1.5V 0.075V

• Data rate

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

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

— 1866Mbps/1600Mbps/1333Mbps (max)

• 1KB page size

• Data mask (DM) for write data

— Row address: A0 to A15

— Column address: A0 to A9, A11 (EDJ4204BFBG)

A0 to A9 (EDJ4208BFBG)

• Posted /CAS by programmable additive latency for

better command and data bus efficiency

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

— Synchronous ODT

— Dynamic ODT

— Asynchronous ODT

• Multi Purpose Register (MPR) for pre-defined pattern

read out

• ZQ calibration for DQ drive and ODT

• Programmable Partial Array Self-Refresh (PASR)

• /RESET pin for Power-up sequence and reset function

• SRT range:

• 2KB page size (EDJ4216BFBG)

— Row address: A0 to A14

— Column address: A0 to A9

• Eight internal banks for concurrent operation

• Interface: SSTL_15

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

• Burst type (BT):

— Sequential (8, 4 with BC)

— Interleave (8, 4 with BC)

• /CAS Latency (CL): 5, 6, 7, 8, 9, 10, 11, 13

• /CAS Write Latency (CWL): 5, 6, 7, 8, 9

— Normal/extended

• Programmable Output driver impedance control

• Precharge: auto precharge option for each burst

access

• Driver strength: RZQ/7, RZQ/6 (RZQ = 240Ω)

• Refresh: auto-refresh, self-refresh

• Refresh cycles

— 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
