PY25Q128HA-SUH-IT 产品概述
一、产品简介
PY25Q128HA-SUH-IT 为 PUYA（普冉）推出的一款 128Mbit 串行闪存器件，采用标准 SPI 接口并提供工业级温度范围（-40℃ 至 +85℃）。器件支持高速时钟（fc 最高达 133MHz），适用于程序代码映射执行或大容量数据存储场景。封装为 SOP-8，便于常规贴片和替换设计。
二、主要参数
- 存储容量：128Mbit（16MByte）
- 接口类型：SPI
- 时钟频率（fc）：133MHz
- 工作电压：2.7V ~ 3.6V
- 待机电流：15 μA
- 擦写寿命：100,000 次
- 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
- 工作温度：-40℃ ~ +85℃
- 封装：SOP-8
三、功能特性
- 硬件写保护：通过 WP 管脚实现物理写保护，适合防篡改和固件保护需求。
- 写使能锁存：采用写使能命令防止误写操作，确保写入前的明确授权。
- 软件写保护：支持对扇区/区域进行软件级保护，灵活控制写入权限。
- 上电复位（POR）：上电自动复位，保证器件在稳定电源后进入确定状态。
- 灵活擦除架构：支持按块/按页编程与擦除，既适合代码映像也适合数据文件管理。
四、典型应用
- 嵌入式系统的程序存储（代码在外部或片内 RAM 中执行）
- 消费类电子产品固件存储与升级（电视、机顶盒、路由器等）
- 数据记录与日志保存（需长期保存且可靠性高的存储）
- 工业设备固件与配置参数存储（依赖工业温度范围与高擦写寿命）
五、设计与选型建议
- 电源旁路：在 VCC 处放置 0.1 μF 陶瓷电容与 1 μF 电解电容以抑制瞬态噪声。
- WP / HOLD 管脚：根据系统需求添加上拉/下拉，启用硬件写保护时注意电平约束。
- 写操作流程：写入前务必执行写使能（WREN），利用软件/硬件保护避免误写。
- 耐久与寿命：针对 100k 次擦写寿命，关键数据区域建议采用磨损均衡或循环计数策略，以延长总寿命。
- 数据完整性：建议在关键写入处使用 CRC/校验与冗余备份机制，配合 20 年数据保留特性提升可靠性。
六、包装与订货信息
- 品牌：PUYA（普冉）
- 型号：PY25Q128HA-SUH-IT
- 封装：SOP-8
- 适用级别：工业温度（IT）

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
