W634GU6RB-11 产品概述

一、产品简介

W634GU6RB-11 是华邦(WINBOND)出品的一款低电压 DDR3L 动态随机存取存储器(SDRAM),单颗容量 4Gbit,内部组织为 256M × x16,适用于需要高带宽、低功耗的嵌入式系统与消费电子设备。该器件工作电压以 1.35V 为目标值,允许电压范围 1.283V ~ 1.45V;内部时钟核心频率 fc = 933MHz(对应 DDR 数据传输率 1866MT/s)。

二、主要特点

  • 低电压工作:DDR3L 1.35V 典型工作点,有利于系统整体功耗下降。
  • 高速传输:fc = 933MHz(DDR 1866MT/s),在理论条件下单芯片峰值带宽可达约 3.73 GB/s(1866MT/s × 16bit / 8)。
  • 存储组织:4Gbit(256M × x16),适合需要中高容量并行数据通道的应用。
  • 宽温工作:规定工作温度 0°C ~ +95°C,适用于部分工业/车规附近的高温环境(具体使用场景请以厂商资料为准)。
  • 标准化接口:兼容 DDR3/DDR3L 控制器的时序与命令集(请在设计中确认初始化与电源序列要求)。

三、典型应用

  • 网络设备与通信终端(路由器、交换机缓存等);
  • 多媒体处理与视频缓冲(机顶盒、数字电视、流媒体设备);
  • 嵌入式系统与单板计算(工业控制、边缘计算模块);
  • 存储控制器与缓存子系统(需高带宽短延迟的场合)。

四、关键参数与说明

  • 存储架构(格式):SDRAM DDR3L(低电压 DDR3);
  • 时钟频率(fc):933MHz(对应 DDR 数据率 1866MT/s);
  • 容量:4Gbit(组织:256M × x16);
  • 工作电压:1.283V ~ 1.45V(典型 1.35V);
  • 工作温度:0°C ~ +95°C;
  • 数据总线位宽:x16(单芯片并行传输 16 位);
  • 包装/封装:资料中未指明,封装形式(BGA/SOP 等)请以华邦官方数据手册与销售资料为准。
  • ECC:该型号说明中未明确 ECC 支持,常见为非 ECC 器件;如需 ECC 功能请向厂方确认。

五、设计注意事项

  • 电源与 Vref 管理:DDR3L 对电源序列、VTT/VREF 的要求严格,设计时应按 JEDEC 推荐序列布局并做好稳压与去耦。
  • 布线与信号完整性:时钟及高速地址/命令/数据线需要差分/阻抗控制与匹配长度(特别是在 x16 并联或多器件布局时)。
  • 时序与初始化:确认控制器对 1866MT/s 工作点的支持,并参考器件时序表调整 CAS、tRCD、tRP 等参数。
  • 散热与环境:虽然支持较高工作温度,仍需结合系统散热设计以保证长期可靠性。
  • 封装与焊接:不同封装对应的 PCB pad 与回流曲线不同,采购前请索取并核对封装图与焊接规范。

六、采购与资料建议

  • 建议在确定使用前获取华邦官方数据手册(datasheet)与器件定级文件,确认具体时序、封装形式、可靠性与认证信息。
  • 若需样片、批量采购或更详细的时序/仿真模型(IBIS/SPICE),请联系华邦授权经销或业务支持,便于获得最新版本的规格说明与参考设计。

总结:W634GU6RB-11 为一款面向高带宽、低功耗应用的 4Gbit DDR3L x16 存储器,适用于多种嵌入式与网络多媒体场景。为保证设计与量产顺利,务必以华邦官方数据手册为准并在系统级进行信号、电源与热管理验证。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
