AT25SF161B-SSHB-T是瑞萨电子推出的一款16Mbit(2MB)容量SPI NOR FLASH存储器,针对中容量存储需求设计,兼顾高速传输、低功耗与工业级可靠性,广泛适配工业控制、消费电子及物联网终端等场景,是嵌入式系统固件存储、配置数据存储的理想选择。
该产品属于瑞萨NOR FLASH产品线中的中容量型号,以SPI四I/O高速接口为核心,解决了传统存储器件在“速度-功耗-可靠性”平衡上的痛点:既满足嵌入式系统对固件加载、OTA升级的高速需求,又适配电池供电设备的低功耗要求,同时支持工业级 harsh环境下的长期稳定运行。
采用SOIC-8封装,尺寸紧凑(典型封装约5.3mm×6.0mm),适合高密度PCB布局,满足小型化产品设计需求。
高速传输,提升系统效率
108MHz Quad SPI接口支持双向高速传输,可快速完成嵌入式系统启动时的固件加载、OTA固件升级等操作,避免系统卡顿,提升用户体验。
低功耗设计,适配电池设备
15uA的待机电流在同类产品中处于领先水平,尤其适合物联网终端(如智能门锁、环境传感器)、便携医疗设备等电池供电场景,减少待机能耗,降低电源设计难度。
工业级可靠性,稳定耐用
-40℃~+85℃的工作温度覆盖多数工业与户外应用;10万次擦写寿命满足频繁固件更新需求(如智能设备每月OTA更新,可支持近8年持续更新);20年数据保留确保配置参数、校准数据等关键信息长期有效。
灵活擦写,适配多样需求
4KB块擦除与1.8ms页写入的组合,既可以快速擦除小容量数据(如配置参数修改),又能高效写入批量数据(如固件段),避免大单元擦除带来的额外开销。
工业控制领域
如PLC(可编程逻辑控制器)、工业传感器节点、电机驱动控制器等,工业级温度与高可靠性确保设备在工厂环境中稳定运行,Quad SPI高速接口支持实时数据缓存与固件更新。
消费电子与智能家居
如智能音箱、智能门锁、便携音频播放器等,低功耗适配电池供电,小封装满足产品小型化设计,高速接口支持OTA固件升级与快速数据读取。
物联网终端
如环境监测节点、智能电表、无线网关等,待机低功耗延长电池续航,16Mbit容量可存储传感器校准数据、历史日志与固件,Quad SPI接口支持与MCU的高速通信。
车载辅助存储
虽未明确标注AEC-Q认证,但工业级温度范围可适配部分车载信息娱乐系统的辅助存储(如仪表盘固件、导航配置数据),满足车载环境的基本可靠性需求。
AT25SF161B-SSHB-T以“高速、低功耗、工业级可靠性”为核心,是一款适配多场景的中容量SPI NOR FLASH存储器。其紧凑的SOIC-8封装、宽电压范围与灵活的擦写特性,使其成为嵌入式系统存储的理想选择,尤其适合对功耗与可靠性有严格要求的工业与物联网应用。

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.
