PY25Q128HA-SUH-IR 产品概述
一、产品简介
PY25Q128HA-SUH-IR 是 PUYA（普冉）推出的一款高密度串行闪存器件，容量为128Mbit（16MB），采用标准 SPI 接口，最高工作时钟频率可达133MHz。该器件专为大批量消费类电子设计，常用于存储启动代码、固件与数据，支持将程序从闪存复制到嵌入式或外部 RAM 后执行，灵活性高，无需额外存储设备即可满足多数数据存储需求。
二、主要规格与性能
- 接口类型：SPI（串行外设接口），兼容主流 MCU/SoC 的 SPI 时序与命令集。
- 存储容量：128Mbit（16MByte）。
- 时钟频率：最高 133MHz（fc）。
- 工作电压：2.7V ~ 3.6V，支持典型 3.3V 系统。
- 待机电流：约 15μA，适合低功耗应用。
- 页写入时间 (Tpp)：2.4ms（典型）。
- 写周期时间 (Tw)：8ms（典型）。
- 擦写架构：灵活的分区与页擦除粒度，适合程序与数据混合存储。
三、可靠性与耐久性
- 擦写寿命：可达 100,000 次，满足长期反复写入需求。
- 数据保留（TDR）：典型可达 20 年，适合长期存储固件与重要配置信息。
这些指标确保器件在消费类产品和工业级应用中的长期稳定性。
四、保护与控制特性
- 硬件写保护：支持外部引脚进行物理写保护，防止意外擦写。
- 写使能锁存（Write Enable Latch）：写入需先使能，降低误写风险。
- 软件写保护：通过命令设置保护区域或块级保护。
- 上电复位（POR）：上电时自动复位，保障系统上电稳定性。
五、典型应用场景
适用于路由器、机顶盒、智能家电、物联网终端、数码相机、便携式播放器、工业控制器与其他需大容量非易失存储的场景，尤其在固件存储与启动代码保管方面表现优异。
六、封装与机械信息
封装形式为 SOP-8-208mil，便于传统贴装与手工焊接，适配常见 PCB 布局与封装工艺。具体引脚定义与封装尺寸请参考器件数据手册以确保设计兼容性。
七、设计注意事项
- 电源去耦：建议在 VCC 附近放置 0.1μF 陶瓷电容以抑制瞬态噪声。
- 电平兼容：确保主控器件 SPI 电平与本器件工作电压匹配，必要时使用电平移位电路。
- 写保护使用：在需要防止固件被篡改或误写的场合，建议同时启用硬件与软件写保护。
- 时序与擦写策略：合理规划擦写与写入操作，避免频繁整块擦写以延长寿命。
PY25Q128HA-SUH-IR 以其高密度、低功耗和完善的保护机制，为需要可靠非易失存储的系统提供了经济且稳定的解决方案。欲了解更详细的电气特性、命令集与封装尺寸，请查阅 PUYA 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.
