FEATURES

DESCRIPTION

Double-data-rate architecture

The WED3DG6433S is a 32Mx64 Double Data Rate

SDRAM memory module based on 128Mb DDR SDRAM

component. The module consists of sixteen 16Mx8 DDR

SDRAMs in 66 pin TSOP package mounted on a 184 Pin

FR4 substrate.

Bi-directional data strobes (DQS)

Differential clock inputs (CK & CK#)

Programmable Read Latency 2,2.5 (clock)

Programmable Burst Length (2,4,8)

Programmable Burst type (sequential & interleave)

Edge aligned data output, center aligned data input

Auto and self refresh

Synchronous design allows precise cycle control with the

use of system clock. Data I/O transactions are possible on

both edges and Burst Lenths allow the same device to be

useful for a variety of high bandwidth, high performance

memory system applications.

Serial presence detect

JEDEC standard 184 pin DIMM package

Power Supply: 2.5V ± 0.25V
