PY25Q128HA-SSH-IR 产品概述

一、产品简介

PY25Q128HA-SSH-IR 是普冉(PUYA)推出的一款 128Mbit 串行闪存存储器,采用 SPI 接口,设计面向大批量消费类应用。器件可在 2.7V~3.6V 宽电源电压范围内完成读取、编程与擦除,无需额外编程电压,程序代码可在启动时从闪存复制到嵌入式或外部 RAM 中执行。器件的擦除架构灵活,既支持页面级操作也具备优化的块擦除粒度,既适合程序代码存放也适合数据存储,能有效减少内存碎片与空间浪费。

二、主要参数

  • 存储容量:128 Mbit
  • 接口类型:SPI(串行外设接口)
  • 最大时钟频率 (fc):133 MHz
  • 工作电压:2.7 V ~ 3.6 V
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 待机电流:15 µA(典型)
  • 擦写寿命:100,000 次(典型)
  • 写周期时间 (Tw):8 ms
  • 页写入时间 (Tpp):500 µs
  • 块擦除时间 (tBE):160 ms
  • 数据保留 (TDR):20 年
  • 封装形式:SOP-8
  • 品牌:PUYA(普冉)

三、功能特性

  • 硬件写保护:支持外部引脚或器件级硬件保护,防止意外写入或擦除。
  • 写使能锁存:写操作需先执行写使能命令,提高写操作安全性。
  • 软件写保护:提供软件层级的保护机制,支持对特定区域进行保护设置。
  • 上电复位(POR):上电自检及复位功能,确保器件在稳定电压下开始工作。
  • 安全寄存器:内部包含 3 × 1024 字节安全寄存器,带有一次性可编程(OTP)锁定功能,适用于设备序列号、系统级电子序列号或密钥等的永久性存储与锁定。
  • 无需额外编程电压:在工作电压范围内即可完成所有编程与擦除操作,简化电源设计。

四、优势与适用场景

  • 存储与执行兼顾:优化的擦除粒度和块大小适合代码与数据混合存放,便于引导程序、固件升级与文件系统实现。
  • 高速传输:高达 133 MHz 的 SPI 时钟支持快速读取,满足启动加速与频繁读取需求。
  • 可靠长寿命:100k 擦写寿命与 20 年的数据保持期,适用于消费电子、智能家居、工业终端等需要长期可靠性的场景。
  • 安全存储:OTP 安全寄存器为序列化和密钥存储提供硬件级保障,便于实现设备身份认证与防篡改策略。

五、设计注意事项

  • 电源管理:建议在 2.7V~3.6V 范围内稳定供电,避免上电/掉电过程中出现电压抖动以确保 POR 正常工作。
  • 写保护策略:结合硬件写保护引脚与软件保护机制可提高数据安全性,推荐关键区采用 OTP 锁定。
  • 擦写规划:由于擦写时间与寿命限制,应用中应合理分配擦写负载,采用 wear-leveling 或文件系统以延长寿命。
  • 封装选型:SOP-8 封装便于中小批量生产与手工焊接,若需更小封装或 BGA,请与供应商确认替代型号。

PY25Q128HA-SSH-IR 以其稳定的性能、丰富的保护机制和适配多种消费级应用的灵活擦除架构,为固件存储、系统序列化及数据保护提供了可靠、经济的方案。若需更详细的电气特性、命令集与时序图,请参考器件数据手册或联系供应商技术支持。

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
