P25Q21H-SSH-IR 产品概述
一、产品简介
P25Q21H-SSH-IR 是普冉（PUYA）出品的一款高可靠性 SPI 闪存，容量 2Mbit（256KB），最高时钟频率 104MHz，工作电压范围宽（2.3V ~ 3.6V），适用于要求容量适中、访问速度快且可靠性高的嵌入式存储场景。器件支持上电复位与多重写保护机制，便于系统级安全与数据完整性保障。
二、主要性能参数
- 接口类型：SPI，最高时钟 fc = 104MHz。
- 存储容量：2Mbit（256KB）。
- 工作电压：2.3V ~ 3.6V，适配 2.7V/3.3V 常见系统电源。
- 待机电流：9 μA（低功耗，适合电池供电设备）。
- 擦写寿命：100,000 次；数据保留（TDR）：20 年。
- 常见时序：写周期 Tw = 8 ms，页写入时间 Tpp = 2 ms，块擦除时间 tBE = 8 ms。
三、功能特性
- 硬件写保护（WP）与绝对写保护，支持外部管脚物理保护。
- 写使能锁存（Write Enable Latch）与软件写保护机制，支持灵活的写入控制策略。
- 上电复位（POR），确保器件在上电瞬间回到确定状态，避免误操作。
四、封装与可靠性
- 封装：SOP-8-150mil，便于标准插板与自动贴装生产。
- 工作温度：-40°C ~ +85°C，满足工业级应用对温度范围的要求。
- 高耐久性与长期数据保存，适合需要长期固化代码或参数的场景。
五、典型应用
适用于嵌入式系统引导存储、固件与配置参数保存、工业控制器、物联网终端、消费电子产品、网络设备等对小容量可靠非易失性存储有要求的产品。
六、设计与使用建议
- 设计时请保证 VCC 在 2.3V~3.6V 范围内，避免在电源不稳定时写操作；建议在电源引脚并联合适的去耦电容。
- 在执行写/擦操作时遵循 Tw、Tpp、tBE 等时序，并通过状态寄存器或命令轮询确认器件空闲后再发起后续操作（详见芯片手册）。
- 合理利用硬件/软件写保护功能提升数据安全，特殊情况下结合外部复位或电源管理电路保证数据一致性。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
