AT45DB041E-SHN-T 为 RENESAS 提供的一款串行 NOR Flash(DataFlash)存储器,容量 4Mbit,组织为 2048 页 × 264Byte,采用标准 SOIC-8-208mil 封装。器件通过 SPI 接口工作,最高时钟频率 fc 可达 85MHz,适用于需要小型、低功耗且可靠非易失性存储的嵌入式系统。
该器件具备高擦写寿命(10^5 次)与长期数据保持能力(20 年),适合长期运行且需频繁更新的配置或日志存储。工作温度范围覆盖工业级要求,满足多数工业与仪表应用的使用场景。
SOIC-8-208mil 标准封装便于 PCB 摆放与手工焊接。设计时建议在 VCC 近旁放置 0.1µF 去耦电容,并在电源引脚和地之间增加额外的滤波以抑制瞬态噪声。SPI 片选线(CS)建议由主控合理驱动,避免总线上争用。
该产品以其高速 SPI、工业级电压与温度范围、低功耗及高可靠性,适合对中等容量非易失性存储有严格性能与寿命要求的嵌入式系统。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
