AT25SF041B-MAHD-T 产品概述

一、产品简介

AT25SF041B-MAHD-T 是瑞萨(RENESAS)推出的一款 4Mbit SPI NOR Flash 存储器,支持四线 I/O(Quad I/O)模式,最高工作时钟可达 108MHz,适用于需要快速执行代码与可靠数据存储的嵌入式系统。器件工作电压范围为 2.5V 至 3.6V,工作温度范围为 -40℃ 至 +85℃,适配多数工业级与消费级产品设计。

二、主要特性

  • 存储容量:4 Mbit(512 KByte)。
  • 接口类型:标准 SPI,支持 Single/Dual/Quad I/O 读取模式,提高数据吞吐。
  • 最高时钟频率:108 MHz,满足高性能代码执行与快速数据读出需求。
  • 低功耗待机电流:典型 25 μA,便于电池供电或低功耗系统设计。
  • 擦写寿命:100,000 次(典型),适合常规固件升级与数据更替场景。
  • 数据保持(TDR):20 年,保证长期非易失性存储可靠性。

三、电气与性能参数

  • 供电电压:2.5 V ~ 3.6 V,兼容 3.3 V 系统,部分 2.5 V 设计也可直接驱动。
  • 工作温度:-40℃ 至 +85℃,适用于多数工业与户外应用(非 AEC-Q100 汽车等级,需另行确认)。
  • I/O 特性:四 I/O 总线支持并行传输,提高读取效率;兼容传统 SPI 指令集与扩展快速读指令。
    在设计时建议在 VCC 引脚旁放置 0.1 μF 陶瓷旁路电容,并关注 PCB 上电平完整性与串扰控制。

四、存储组织与可靠性

器件采用 NOR 架构,适合执行原地(XIP)代码存储及随机地址读取。耐久性高、擦写循环额定 100k 次,配合 20 年数据保持特性,满足固件长期维护与可靠存储需求。为延长寿命,设计上可采用磨损均衡与差分更新策略,避免频繁针对同一扇区的写擦。

五、封装与机械特性

  • 封装形式:USON-8-EP(2x3),亦称 8-UDFN(2x3)。
  • 小型化的贴片封装,带裸露散热焊盘(EP),有利于热管理与可靠焊接。适合空间受限的便携与物联网终端。

六、典型应用与使用建议

  • 典型应用:MCU/MPU 的代码与引导存储、固件更新(FOTA)、配置参数与校准数据保存、工业控制器、消费电子、物联网终端等。
  • 设计建议:推荐在 CS、CLK 与 I/O 走线最短化并加入适当串联阻抗抑制反射;对 WP/HOLD 等保护引脚(若使用)应按需求加上上拉或下拉电阻以避免误触发;布局时保证裸露焊盘良好焊接以提升热与机械可靠性。

七、采购与支持

型号:AT25SF041B-MAHD-T,品牌:RENESAS(瑞萨)。器件适用于需要紧凑封装与高速 SPI 读取的设计。采购前请核对封装、温度等级与工作电压与项目需求一致,并参考瑞萨官方数据手册获取完整指令集、时序参数、电气特性和可靠性试验数据以进行最终设计验证。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
