P25D40SH-SSH-IT 产品概述

一、概述

P25D40sH(P25D40SH-SSH-IT)是普冉(PUYA)推出的一款4Mbit串行闪存器件,采用标准SPI接口,面向大批量消费类与工业控制类应用。该器件以低功耗、高可靠性和灵活的擦除/编程架构为设计重点,常用于程序代码在上电后复制到内/外部RAM并执行的系统,也适合按页级别存储与管理用户数据,无需额外存储器。

二、主要参数亮点

  • 存储容量:4 Mbit(512 KB)
  • 接口类型:SPI 串行接口,支持高速时钟,最大工作频率 fc = 104 MHz
  • 工作电压:2.3 V ~ 3.6 V,兼容常见 2.5V/3.3V 系统
  • 工作温度:-40 ℃ ~ +85 ℃(工业级)
  • 待机电流:典型 10 μA(低功耗待机)
  • 擦写寿命:100,000 次(典型)
  • 数据保留(TDR):10 年
  • 写周期时间(Tw):8 ms(整页或块写入周期)
  • 页写入时间(Tpp):2 ms(页级写入响应快)
  • 封装:SOP-8-150mil,便于通用PCB布局与回流焊接

三、功能与可靠性

  • 写保护机制:提供硬件写保护与绝对写保护(WP/hold 类引脚),并支持写使能锁存与软件写保护命令,便于多层次保护关键代码与数据。
  • 上电复位(POR):内置上电复位电路,保证电源不稳定时器件处于安全状态,避免误写或数据损坏。
  • 擦写架构:灵活的擦除粒度与页编程特性适合代码与数据并存的应用场景,减小擦写放大,延长器件寿命。
  • 可靠性指标:高耐久(10万次擦写)与十年数据保持,适合长期部署的消费与工业设备。

四、典型应用与设计建议

  • 典型应用:数字机顶盒、电视与家电控制板、路由器与网关、监控设备、便携式多媒体、固件存储与配置数据备份等。
  • 设计建议:
    • 电源侧加 0.1 μF 及 1 μF 旁路电容,靠近VCC引脚以抑制瞬态噪声;
    • 在WP/CS/HOLD引脚上根据系统需要配置上拉/下拉,确保上电时处于预期保护状态;
    • 遵循SPI时序规范及上电/掉电顺序,利用器件的POR功能确保安全初始化;
    • 对频繁写入的数据区做磨损均衡与写入节流策略,延长器件寿命。

五、封装与型号信息

  • 型号:P25D40sH-SSH-IT
  • 品牌:PUYA(普冉)
  • 封装形式:SOP-8-150mil,适用于自动贴片与常规插装工艺。

总结:P25D40sH 以其工业级温度范围、低功耗特性、完善的写保护机制及高擦写耐久度,是需要可靠固件存储与页级数据管理的消费类与工业嵌入式产品的合适选择。若需针对此型号的引脚定义、命令集或典型时序图,我可以提供更详细的设计资料与参考电路。

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
