P25Q80SH-SSH-IT 产品概述

一、产品简介

P25Q80SH-SSH-IT(品牌:PUYA/普冉)是一款高速串行闪存芯片,容量为8Mbit(1MByte),采用标准SPI接口,最高支持120MHz时钟频率。该器件专为大批量消费类产品设计,支持代码与数据在外部或嵌入式RAM中映射执行,具备灵活的擦写架构与页级写入特性,适合程序存储与数据存储的二合一解决方案。

二、主要规格

  • 存储容量:8Mbit(1MByte)
  • 接口类型:SPI
  • 最大时钟频率(fc):120MHz
  • 工作电压:2.3V ~ 3.6V
  • 工作温度范围:-40℃ ~ +85℃
  • 待机电流:10 μA
  • 擦写寿命:100,000 次
  • 数据保留(TDR):20 年
  • 页写入时间(Tpp):1.5 ms
  • 写周期时间(Tw):8 ms
  • 块擦除时间(tBE):16 ms
  • 封装:SOP-8
  • 功能特性:硬件写保护、写使能锁存、软件写保护、上电复位

三、关键功能特性

  • 硬件写保护:提供外部引脚控制的写保护功能,便于在系统需要时物理禁止写操作,提升安全性。
  • 写使能锁存(WEL):通过写使能指令控制写入状态,避免误操作造成数据破坏。
  • 软件写保护:支持基于命令或寄存器的区域保护,灵活配置受保护的存储区。
  • 上电复位(Power-on Reset):上电时保证芯片进入已知状态,提升系统可靠性。
  • 可映射执行:支持将程序代码映射到嵌入式或外部RAM执行,满足代码存储与运行分离的需求。

四、存储结构与性能

P25Q80SH具有灵活的擦写架构和页级写入能力,适合既需频繁写入小量数据又需整块擦除的场景。页写入延时为约1.5 ms,每次写周期最大约8 ms;块擦除时间约16 ms,配合高达120 MHz的读时钟,可在应用端实现快速引导与数据读取。建议在设计时依据数据访问模式选择合适的擦除与写入策略,以延长器件寿命并优化性能。

五、功耗与可靠性

  • 待机电流仅为10 μA,适合对低功耗有要求的便携或待机型设备。
  • 擦写寿命达100,000次,满足大多数消费与工业应用的长期使用需求。
  • 数据保留保证约20年,在长期归档与固件保存方面具有可靠性优势。
  • 工作温度范围宽,适用于常见工业与民用环境。

六、封装与接口

  • 封装类型:SOP-8,便于贴片组装与批量生产。
  • 接口:标准SPI信号(CS、SCLK、MOSI、MISO)兼容主流MCU与SPI控制器,120 MHz时钟支持高速读传输。具体引脚功能及时序请参考详细数据手册。

七、典型应用

  • 嵌入式系统的程序存储与引导代码(Boot ROM)
  • 家电、电视机顶盒、路由器等消费类电子的固件存储
  • 数据记录、配置参数与日志存储
  • 工业控制与通信设备的非易失性存储

八、设计注意事项

  • 电源:采用稳定电源并在VCC端路由去耦电容,防止写/擦操作时出现电压跌落。
  • 时序与命令:严格遵循厂商数据手册的命令序列和时序要求,特别是写使能、写保护与擦除流程。
  • 写保护策略:合理使用硬件与软件写保护以防止错误写入,关键区域可配置为永久只读。
  • 布局:SPI信号线尽量短且布线一致,避免长线引入的信号完整性问题,必要时在SCLK与CS上添加阻尼或终端匹配。
  • 可靠性验证:在目标温度与电源条件下进行擦写寿命与数据保留验证,评估实际应用寿命与容错方案。

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
