PY25Q32HB-SSH-IT 产品概述
一、产品简介
PY25Q32HB-SSH-IT 是普冉（PUYA）推出的一款 32Mbit 串行闪存器件，采用标准 SPI 接口，最高时钟频率 fc=133MHz，支持将程序代码映射至嵌入式或外部 RAM 执行（XIP）。器件提供灵活的擦除架构和优化的擦除块大小，既适合代码存储也适用于高容量数据保存，无需另外增加数据存储器件即可满足多种消费级应用需求。
二、主要规格
- 存储容量：32Mbit（4MB）
- 接口类型：SPI（最高 133MHz）
- 工作电压：2.3V ~ 3.6V
- 待机电流：18 µA（典型）
- 擦写寿命：100,000 次（典型）
- 数据保留（TDR）：20 年
- 工作温度范围：-40℃ ~ +85℃
- 封装形式：SOP-8-150mil
- 型号：PY25Q32HB-SSH-IT（PUYA）
三、关键功能特性
- 硬件写保护：提供物理引脚级写保护，方便在系统层面防止误写入。
- 写使能锁存（WEL）：写操作前需设置写使能锁存以保障意外写入保护机制。
- 软件写保护：支持通过寄存器软件配置的保护机制，实现对部分区域的保护。
- 上电复位（POR）：器件上电自动复位，确保上电初始化后处于可预期状态。
四、性能与时序
- 页写入时间（Tpp）：400 µs（典型）
- 块擦除时间（tBE）：120 ms（典型）
- 这些时序指标对系统设计的写入/擦除策略和电源管理具有参考价值，适用于周期性写入和大块更新场景。
五、应用场景
- 消费类电子：智能家居终端、机顶盒、智能音箱等需要外部代码或数据存储的设备。
- 工业嵌入式：在 -40℃ 至 +85℃ 环境下工作的 MCU/FPGA 配套存储器。
- 固件与参数保存：适用于固件存储、配置参数持久化及日志存储等场景。
六、设计建议与注意事项
- 电源规划：在 2.3V~3.6V 范围内保证稳定电源，避免过冲或下陷导致数据异常。
- 写保护策略：结合硬件写保护与软件保护提升系统可靠性；关键区建议启用硬件写保护。
- 擦写磨损管理：采用磨均衡和坏块管理、减少对同一区域的频繁擦写以延长使用寿命（100k 擦写循环为典型耐久）。
- 时序留裕：在高负载或冷启动情形下，预留足够的写入/擦除时间，避免中断写入操作。
PY25Q32HB-SSH-IT 以其高频 SPI 接口、优化的擦除粒度与全面的保护机制，为需要高容量、可靠性的消费级和工业级存储应用提供了灵活且高效的解决方案。若需详细引脚定义、命令集或典型应用电路，请参考产品规格书或联系供应商获取完整技术资料。

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.
