XT25F128FWOIGT 产品概述

一、产品简介

XT25F128FWOIGT 是 XTX(芯天下)推出的一款 128Mbit 串行闪存,采用标准 SPI 接口,工业级温度等级,封装为 WSON8 6×5mm。器件工作电压范围为 2.7V~3.6V,适用于对容量、可靠性和封装尺寸有较高要求的嵌入式系统与工业控制场景。

二、核心参数

  • 存储容量:128 Mbit(16 MByte)
  • 接口类型:SPI(标准串行接口)
  • 最大时钟频率 (fc):104 MHz
  • 工作电压:2.7 V ~ 3.6 V
  • 待机电流:1 μA(典型,具体请参见详尽数据手册)
  • 擦写寿命:100,000 次(典型)
  • 页写入时间 Tpp:400 μs(典型)
  • 块擦除时间 tBE:150 ms @ 32 KB(典型)
  • 数据保留 TDR:20 年
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:WSON8 6×5 mm,工业级

三、主要特性

  • 高密度:128 Mbit 满足代码存储、固件更新与数据日志需求。
  • 低功耗:1 μA 待机电流,有利于电池供电或低功耗系统。
  • 快速响应:支持最高 104 MHz 时钟,顺序读取性能良好,满足启动与执行读取需求。
  • 高可靠性:100k 擦写寿命与 20 年数据保留,适合长期运行的工业设备。
  • 紧凑封装:WSON8 6×5mm,节省 PCB 面积,便于高度集成设计。

四、典型应用

  • MCU/MPU 的外部闪存存储与引导(Boot)代码存储
  • 固件在线升级(FOTA)镜像存储
  • 工业控制器、PLC、传感器网关的参数与日志保存
  • 物联网设备、消费电子中固件与资源文件存储

五、封装与可靠性说明

WSON8 6×5mm 小外形封装,适合面向空间受限设计。封装通常带底部散热/接地焊盘,推荐将该焊盘焊接到 PCB 的大地铜箔以提高散热与电气接地性能。器件通过工业级温度测试,-40℃~+85℃ 运行可靠性良好。

六、设计建议

  • 电源:在 VCC 引脚附近放置 0.1 μF 贴片去耦电容,必要时并联 1 μF 以抑制瞬态。严格按照 2.7V~3.6V 供电规范设计。
  • PCB 布线:SPI 信号线尽量短、直,优先走地平面下的信号层,减少串扰与阻抗不连续。
  • 片选与保护:对 CS、WP、HOLD 等控制信号采用上拉/下拉以保证复位及掉电时的确定状态;焊盘加固以满足振动环境。
  • 热管理与焊盘:WSON 底部金属焊盘请按厂家推荐焊盘图布局,多通孔焊接至内层地以改善散热与焊接可靠性。
  • 软件:采用主流 SPI NOR Flash 驱动即可集成,考虑擦写与写入延时(Tpp、tBE)实现写入完成检测与错误重试机制。

七、结论

XT25F128FWOIGT 是一款面向工业与嵌入式市场的高可靠 128Mbit SPI 闪存,兼具低功耗、高擦写寿命与紧凑封装,适合用于固件存储、启动代码与长期数据保存。为确保最佳表现,请参考官方数据手册的引脚定义与 PCB 焊盘建议,并在系统设计中考虑去耦、电源完整性与写入/擦除流程管理。若需原理图建议或封装库(PCB footprint),可进一步提供具体需求以便详细支持。

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
