AT45DB081E-SHN-T是瑞萨电子(RENESAS)推出的串行NOR闪存产品,属于DataFlash系列,主打低功耗、高可靠性与紧凑封装,针对嵌入式系统中对配置数据、固件、传感器日志等小容量存储的需求优化设计,兼顾速度与功耗平衡,适用于多场景工业与消费电子应用。
产品总容量为8Mbit(即1MB),采用4096页×264Byte的存储架构——单页容量264Byte(含部分冗余字节,可用于ECC校验或数据备份),这种分块设计支持页级擦除与页级编程,避免跨页操作的性能损耗,适合频繁读写小数据块的场景(如设备配置参数、固件片段)。
采用标准SPI接口(支持SPI模式0/3),仅需4根核心引脚(CLK、MOSI、MISO、CS),结合SOIC-8封装的其他引脚(如WP写保护、HOLD保持),实现紧凑的硬件连接,大幅节省PCB空间,适配高密度设计的嵌入式模块。
封装规格为SOIC-8-208mil(小外形集成电路,8引脚,引脚间距208mil),表面贴装工艺兼容常规回流焊流程,体积小巧(尺寸约5.2mm×4.4mm),可轻松集成到小型化设备(如智能传感器、蓝牙模块)中,同时具备良好的散热性能与机械稳定性。
AT45DB081E-SHN-T的特性使其适配多类嵌入式应用:
AT45DB081E-SHN-T通过8Mbit容量+SPI高速接口+低功耗+高可靠性的组合,解决了嵌入式系统中“小容量存储、低功耗需求、紧凑设计”的核心痛点,瑞萨的品牌背书与成熟的DataFlash技术,确保产品在工业与消费电子领域的稳定应用,是替代传统并行NOR闪存、提升系统集成度的理想选择。

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.
