The W3EG6433S is a 2x16Mx64 Double Data Rate SDRAM memory module based on 256Mb DDR SDRAM component. The module consists of sixteen 16Mx8 DDR SDRAMs in 66 pin TSOP packages mounted on a 184 pin FR4 substrate. 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.
The W3EG6433S-D3 is a 256 MB, 2 × 16 Mx64 DDR SDRAM memory module built on a JEDEC 184‑pin DIMM package. It supports DDR266 and DDR333 speeds, bi‑directional data strobes, and differential clock inputs. The module operates from a 2.5 V + 0.2 V supply and is available in both RoHS‑compliant and industrial‑temperature versions.
The document provides detailed electrical characteristics, AC operating conditions, capacitance values, absolute maximum ratings, and ordering information, including part numbers for various speed and latency options. It also includes revision history and mechanical dimensions of the module.
