DATA SHEET

128M bits DDR SDRAM

EDD1232ABBH (4M words × 32 bits)

Specifications

Features

• Density: 128M bits

• ×32 organization

• Organization

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

clock cycle

⎯ 1M words × 32 bits × 4 banks

• Package: 144-ball FBGA

⎯ Lead-free (RoHS compliant)

• Power supply: VDD, VDDQ = 2.5V 0.125V

• Data rate: 400Mbps (max.)

• Four internal banks for concurrent operation

• Interface: SSTL_2

• The high-speed data transfer is realized by the 2 bits

prefetch pipelined architecture

• Bi-directional data strobe (DQS) is transmitted

/received with data for capturing data at the receiver

• Data inputs, outputs, and DM are synchronized with

DQS

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

aligned with data for WRITEs

• Burst lengths (BL): 2, 4, 8

• Burst type (BT):

• Differential clock inputs (CK and /CK)

• DLL aligns DQ and DQS transitions with CK

⎯ Sequential (2, 4, 8)

⎯ Interleave (2, 4, 8)

• /CAS Latency (CL): 3

• Precharge: auto precharge operation for each burst

access

transitions

• Commands entered on each positive CK edge; data

and data mask referenced to both edges of DQS

• Data mask (DM) for write data

• Driver strength: weak/matched

• Refresh: auto-refresh, self-refresh

• Refresh cycles: 4096 cycles/32ms

⎯ Average refresh period: 7.8μs

• Operating ambient temperature range

⎯ TA = 0°C to +70°C
