P25D32SH-SSH-IT 产品概述

一、产品简介

P25D32SH-SSH-IT 是普冉(PUYA)推出的高可靠串行闪存产品,容量 32Mbit,标准 SPI 接口,最高时钟频率可达 120MHz。器件封装为 SOP-8-150mil,专为容量要求较高的消费类与嵌入式应用设计,可作为程序与数据存储介质,程序常由闪存复制到片内或外部 RAM 执行。

二、主要规格与性能

  • 接口类型:SPI,最高时钟 fc = 120MHz。
  • 存储容量:32 Mbit(4 MByte)。
  • 工作电压:典型/推荐 2.3V ~ 3.6V;器件支持在更宽电压窗(1.65V ~ 3.6V)下进行读取、编程与擦除(无需额外编程电压)。
  • 工作温度:-40 ℃ ~ +85 ℃。
  • 待机电流:约 10 μA(典型)。
  • 擦写/编程性能:页写入时间 Tpp ≈ 1.6 ms;写周期时间 Tw ≈ 12 ms;块擦除时间 tBE ≈ 30 ms(基于 32 KB 块)。
  • 擦写寿命:擦写次数可达 100,000 次;数据保留(TDR)约 20 年。

三、功能特性与安全

  • 硬件写保护(WP)与绝对写保护支持,提供外部与内部多级写保护机制。
  • 写使能锁存(WEL)、软件写保护(SRP)与上电复位(POR)等控制功能,便于在系统层实现可靠的写操作管理。
  • 内建 3×1024 字节一次性可编程(OTP)安全寄存器,支持设备唯一序列号、系统 ESN、密钥与不可变配置的存储与锁定。

四、适用场景

适用于机顶盒、路由器、消费类电子、嵌入式控制器、工业控制与其他需大量代码或数据存储并要求高可靠性的应用。灵活的擦除粒度和优化的块尺寸有助于提高存储利用率、减少空间浪费,适合既存放程序又作为数据日志存储的混合场景。

五、设计与使用建议

  • 高速 SPI 运行时注意时序与布局:合理布线、去耦和终端匹配,保证 120MHz 时钟下信号完整性。
  • 合理安排页/块对齐与擦写策略以延长器件寿命,并利用写保护与 OTP 做关键数据防护。
  • 在系统上电/复位期间遵循器件上电复位要求,避免在不稳定电源下进行擦写/编程操作。
  • 对关键密钥或序列号建议写入 OTP 并锁定以防止后续更改。

P25D32SH-SSH-IT 以其高密度、快速 SPI 接口、完善的写保护与 OTP 安全特性,为各类需要可靠非易失存储的产品提供了稳定且灵活的解决方案。

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
