P25D22H-TSH-IR SPI串行闪存产品概述

一、产品基本身份与定位

P25D22H-TSH-IR是普冉半导体(PUYA)推出的一款2Mbit容量SPI串行NOR闪存,采用TSSOP-8标准封装,定位于高性价比、低功耗、工业级可靠性的存储器件。其核心适配嵌入式系统的固件存储、参数配置、日志记录等需求,尤其适合对功耗、温度适应性要求较高的场景(如物联网终端、工业传感器)。

二、核心规格参数总览

该产品的关键参数围绕“高速传输、低功耗、宽适配”设计,具体如下:

  • 存储容量:2Mbit(换算为256KB字节),采用页/块组织架构(兼容行业通用页宽设计);
  • 接口类型:标准SPI串行接口,最高支持85MHz时钟频率,实现高速数据读写;
  • 电气特性:工作电压范围2.3V~3.6V,覆盖主流MCU电源;待机电流仅12μA,休眠功耗极低;
  • 操作时间:写周期(Tw)8ms,页写入时间(Tpp)2ms,块擦除时间(tBE)12ms,满足快速擦写需求;
  • 可靠性参数:擦写寿命100,000次,数据保留时间(TDR)10年;
  • 环境适应性:工作温度范围-25℃~+85℃,符合工业级温度标准。

三、关键特性亮点解析

  1. 高速传输能力:85MHz时钟频率支持SPI模式下的快速数据存取,相比低速SPI Flash可提升系统响应效率(如固件升级、实时数据缓存场景);
  2. 低功耗设计:待机电流仅12μA,在电池供电设备(可穿戴、物联网节点)中可显著延长待机时间,降低电源设计难度;
  3. 宽电压与温度适配:2.3V3.6V电压兼容3.3V、2.5V等常见电源,-25℃+85℃工业级温度适应户外、车载、工业现场等恶劣环境;
  4. 高可靠性与长寿命:10万次擦写寿命满足长期使用(按每天10次擦写计算,可用约27年),10年数据保留确保存储数据不丢失;
  5. 封装与兼容性:TSSOP-8封装体积小巧,便于PCB布局;SPI接口兼容STM32、AVR、NXP等主流MCU,无需额外适配电路,降低系统成本。

四、典型应用场景

该产品因特性适配性强,覆盖多领域场景:

  • 消费电子:智能家居节点(智能开关、温湿度传感器)、可穿戴设备(智能手环配置存储);
  • 工业控制:工业传感器、小型PLC、电机控制器的参数与固件存储;
  • 物联网终端:蓝牙/ZigBee模块、环境监测节点的日志与配置存储;
  • 汽车电子:车载小功率控制单元(车窗控制器、氛围灯)的辅助存储(适配-25℃~+85℃环境);
  • 通信设备:低功耗无线网关、小型路由器的固件与配置存储。

五、可靠性保障与选型建议

P25D22H-TSH-IR的可靠性经过普冉严格测试,满足工业级应用需求:

  • 擦写寿命与数据保留:10万次擦写循环+10年数据保留,可应对频繁擦写的参数动态更新场景;
  • 抗干扰性:SPI接口的差分传输特性结合宽电压设计,降低电磁干扰对数据的影响;
  • 选型建议:若系统需256KB容量、低功耗、工业级温度,且采用SPI接口MCU,该产品是高性价比选择;若需更高容量或QPI接口,可考虑普冉同系列其他型号。

该产品以平衡的性能与成本优势,成为嵌入式存储领域的实用之选,适配多种中低端系统的存储需求。

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
