W25N04KVZEIR 是华邦(WINBOND)推出的一款 4G-bit 串行 NAND 闪存器件,面向嵌入式、消费电子和工业应用场景。器件采用 SPI 串行接口,工作电压约为 3V(2.7V~3.6V),并以小尺寸封装(WSON-8,6x8 mm)提供高密度存储解决方案。该器件在读写性能、可靠性和安全防护上进行了优化,适合对尺寸、功耗和系统资源有严格要求的设计。
W25N04KVZEIR 的 SPI 接口在 104 MHz 时钟下可提供较高的串行吞吐能力,适合固件存储、启动镜像及频繁读取的场景。页写入时间 250 μs 与块擦除时间 10 ms 表明在写入或擦除大块数据时需关注主机调度与延时管理。待机电流典型为 20 μA,有利于电池供电或低功耗嵌入式系统的待机能耗优化。
设计时建议:
器件提供 6 万次擦写寿命与 10 年的数据保留能力,适合长期部署的工业级应用。内置 ECC 可纠正常见的位翻转错误,结合 OTP 和硬件写保护、软件写保护机制,为重要数据提供多重防护。设计中还应考虑上层的磨损均衡(wear leveling)、坏块管理与冗余机制,以进一步提升系统级可靠性。
W25N04KVZEIR 提供 WSON-8(6x8 mm)小尺寸封装,适合空间受限的 PCB 设计。小封装结合 SPI 串行接口的低引脚数特性,便于在紧凑型设备(例如智能终端、嵌入式控制器、物联网节点)中实现高密度存储方案。具体封装引脚分配与热管理建议请参阅完整数据手册。
典型应用场景:
设计注意事项:
总结:W25N04KVZEIR 将 4G-bit 串行 NAND 的高密度存储、低引脚接口和多重数据保护机制融合于小尺寸封装,适合对体积、功耗与可靠性有要求的嵌入式与消费类产品。在产品设计初期,应结合数据手册进行时序、电源和软件层面的集成验证,以确保系统稳定可靠运行。

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.
