White Electronic Designs

PRELIMINARY*

256MB – 2x16Mx72 DDR SDRAM REGISTERED ECC, w/PLL

FEATURES

DESCRIPTION

The WED3DG7235S is a 2x16Mx72 Double Data Rate

SDRAM memory module based on 128Mb DDR SDRAM

component. The module consists of eighteen 16Mx8 DDR

SDRAMs in 66 pin TSOP packages mounted on a 184 pin

FR4 substrate.

ꢀ

Double-data-rate architecture

Speeds of 100MHz and 133MHz

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)

Synchronous design allows precise cycle control with the

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

both edges and Burst Lengths allow the same device to be

useful for a variety of high bandwidth, high performance

memory system applications.

Edge aligned data output, center aligned data

input

ꢀ

Auto and self refresh

Serial presence detect

Dual Rank
