AT45DB041E-SSHN-T是瑞萨电子(RENESAS)推出的DataFlash系列串行NOR闪存芯片,专为低功耗、高可靠性的嵌入式存储场景设计,核心定位为中容量、高速SPI接口的存储解决方案,兼顾性能与成本优势。
该芯片总存储容量为4Mbit(512KB),采用“页+扇区”的分层存储结构:
AT45DB041E-SSHN-T采用标准SPI串行接口,支持最高85MHz时钟频率,单SPI模式下数据传输速率可达10.625MB/s,满足中高速场景的固件加载、配置参数读写需求。同时兼容SPI的多线模式(若支持),可进一步提升传输速率,适配高性能MCU系统。
芯片的低功耗特性是核心优势之一:
采用NSOIC-8(窄体SOIC-8) 封装,尺寸紧凑(约4.9mm×3.9mm),节省PCB空间,适合小型化产品设计(如智能穿戴、小型IoT终端)。
该芯片完全兼容标准SPI接口,可直接与瑞萨RA系列、STM32系列等主流MCU对接,无需特殊驱动开发;支持SPI状态寄存器读取,可实时监控擦写完成状态、设备状态,提升系统可靠性。
综上,AT45DB041E-SSHN-T凭借高容量、高速SPI、低功耗与高可靠性,成为嵌入式系统中固件存储、配置参数保存的理想选择,尤其适合小型化、电池供电的终端产品。

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.
