P25Q21H-SSH-IT 产品概述

一、产品简介

P25Q21H-SSH-IT 是普冉(PUYA)推出的一款高性价比串行闪存(SPI NOR Flash),容量为 2Mbit(256KB),面向大批量消费类应用设计。器件采用标准 SPI 接口,支持高达 104MHz 的时钟频率,能够满足系统对快速启动与代码存储的需求。该器件具有灵活的擦写架构和页级写入特性,非常适合用于程序固件存储与数据记录,无需额外外部存储器即可实现嵌入式系统的启动与数据管理。

二、主要规格参数

  • 接口类型:SPI
  • 存储容量:2Mbit
  • 最大时钟频率(fc):104MHz
  • 工作电压:2.3V ~ 3.6V(兼容 3.3V 系统)
  • 待机电流:9µA
  • 擦写寿命(擦写循环):100,000 次
  • 单次写周期时间(Tw):8ms
  • 页写入时间(Tpp):2ms
  • 块擦除时间(tBE):8ms(64KB 块)
  • 数据保留(TDR):20 年
  • 工作温度:-40℃ ~ +85℃
  • 封装:SOP-8
  • 品牌:PUYA(普冉)

三、关键功能特性

  • 硬件写保护(Hardware WP)与绝对写保护(Absolute Protection),支持外部引脚强制保护关键区域。
  • 写使能锁存(Write Enable Latch)与软件写保护机制,提供灵活的软件/硬件混合保护策略。
  • 上电复位(Power-On Reset),确保上电后器件进入确定性状态。
  • 页级写入与可配置擦除架构,既适用于代码存储也能高效处理小粒度数据更新。
  • 低功耗待机与快速读写性能的平衡,适合对功耗与响应时间有双重要求的终端产品。

四、性能与可靠性

P25Q21H 在 104MHz 时序下可实现快速读取与启动,加速系统引导与代码加载。器件支持 100k 次擦写循环与 20 年的数据保持能力,满足长期可靠性需求。待机电流仅 9µA,有利于电池供电或功耗敏感设备的设计。工业级温度范围(-40℃~+85℃)保障在复杂环境中的稳定运行。

五、典型应用场景

  • 嵌入式系统固件存储(启动 ROM、Bootloader)
  • 消费类电子产品(机顶盒、智能家居、数码相机)
  • 工业控制与通信设备的非易失性配置存储
  • IoT 节点与边缘设备固件及参数保存
  • 需要小容量、高可靠性、可保护关键数据的场合

六、封装与系统集成建议

P25Q21H-SSH-IT 提供 SOP-8 封装,便于双列直插或贴片工艺实现。器件工作电压覆盖 2.3V-3.6V,推荐在 3.3V 供电系统中直接使用。设计时建议:

  • 在 VCC 引脚旁放置去耦电容以保证稳定供电。
  • 合理使用 WP/HOLD 引脚实现硬件保护与调试切换。
  • 考虑写/擦操作时间(Tw、Tpp、tBE)进行任务调度与超时处理。
  • 对频繁写入的数据区采用软件层面的磨损均衡策略以延长使用寿命。

七、总结

P25Q21H-SSH-IT 以其高速 SPI 接口、完整的写保护机制、工业级可靠性和低待机功耗,为各种消费类与工业嵌入式应用提供了稳定的非易失性存储解决方案。其灵活的擦写架构与较高的擦写寿命使其既能满足代码存储需求,也适合小粒度的数据存储场景,是兼顾成本与性能的常用选择。若需替代或扩展容量,请参照同系列产品规格进行兼容性评估。

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
