PY25Q32HB-SSH-IR 产品概述
一、简介
PY25Q32HB-SSH-IR 是普冉（PUYA）推出的一款高性价比串行闪存器件，容量 32Mbit，采用标准 SPI 接口并提供 SOP-8 封装。器件针对大量消费类与嵌入式应用进行了优化，允许程序代码映射到嵌入式或外部 RAM 中执行（XIP 或类似方案），同时具备灵活的擦除架构，满足代码与数据存储双重需求，无需额外存储器件。
二、主要参数
- 接口类型：SPI
- 存储容量：32 Mbit
- 最大时钟频率 (fc)：133 MHz
- 工作电压：2.3 V ～ 3.6 V
- 待机电流：典型 40 μA
- 擦写寿命：100,000 次（典型）
- 单次写周期时间 (Tw)：12 ms
- 页写入时间 (Tpp)：约 400 μs
- 块擦除时间 (tBE)：约 120 ms（以 32 KB 块为准）
- 数据保留 (TDR)：20 年
- 工作温度：-40 ℃ ～ +85 ℃
- 封装：SOP-8
三、功能特点
- 硬件写保护（WP/BP 引脚实现）
- 写使能锁存（WEL）与写入使能控制命令
- 软件写保护（多级保护位）
- 上电复位（POR）保证启动稳定性
- 可按扇区/块擦除的灵活架构，擦除块尺寸针对当今代码与数据分配进行了优化，以减少空间浪费并提高存储利用率
四、典型应用场景
- 引导/程序代码存储（MCU/处理器外部闪存）
- 固件与系统升级存储（OTA/本地升级）
- 参数与日志数据保存（消费电子、物联网终端）
- 智能家电、智能音箱、机顶盒、可穿戴设备、工业控制等对成本、稳定性有要求的终端设备
五、设计建议
- 电源引脚应做良好去耦，遵循器件供电与上电复位时序以确保可靠启动。
- 在频繁写入场景建议采用磨损均衡策略与冗余分区，以延长可用寿命（100k 擦写次数为典型值）。
- 写入与擦除操作需考虑 Tw、Tpp、tBE 等时序参数，避免在未完成操作时强行断电或继续访问。
- 合理使用硬件/软件写保护功能，配合固件校验机制，提升存储数据的安全性与完整性。
六、可靠性与长期保存
器件支持工业级工作温度（-40 ℃～+85 ℃），典型数据保留 20 年，并在擦写寿命与电气特性上满足大多数消费与工业类应用的可靠性需求。SOP-8 小型封装便于 PCB 布局与自动化生产。
PY25Q32HB-SSH-IR 以其灵活的擦除架构、稳定的电气特性与完善的写保护功能，是需要外部 SPI 闪存进行代码执行映射与数据保存的终端设备的理想选择。若需更多电气特性曲线、命令集或封装图纸，请参考官方数据手册。

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.
