PY25Q128HA-WXH-IR 产品概述

PY25Q128HA-WXH-IR 是普冉(PUYA)推出的一款高性能串行闪存,采用标准 SPI 接口,容量 128Mbit(16MB),面向嵌入式存储、程序存储和数据记录等应用。器件在工业级温度范围内稳定工作,结合低功耗与高可靠性特性,适合消费类、物联网及工业控制等多种场景。

一、主要参数

  • 接口类型:SPI
  • 存储容量:128Mbit(16M Byte)
  • 最大时钟频率(fc):133 MHz(支持高速读出)
  • 工作电压:2.7 V ~ 3.6 V
  • 待机电流:15 μA(典型)
  • 页写入时间(Tpp):2.4 ms(典型)
  • 擦写寿命:100,000 次(典型)
  • 数据保留(TDR):20 年
  • 工作温度:-40 ℃ ~ +85 ℃
  • 品牌:PUYA(普冉)
  • 封装:WSON-8

二、关键特性与优势

  • 高速读写:支持最高 133 MHz 的 SPI 时钟,能提供较高的串行读出吞吐,满足快速启动与镜像加载需求。
  • 容量与可靠性平衡:128Mbit 容量可容纳完整固件与大量数据,数据保留 20 年、擦写寿命达 100k 次,适合长期部署设备。
  • 宽电压与低功耗:2.7–3.6V 电源范围兼容常见 MCU 系统,待机电流仅 15 μA,有利于低功耗设计。
  • 商用/工业温度支持:-40 至 +85 ℃ 工作温度,适用于多数工业与户外应用。
  • 小型封装:WSON-8 封装体积小,带底部散热/接地焊盘,便于高密度板级布局。

三、封装与典型引脚功能(WSON-8)

WSON-8 常用引脚包括 CS(片选)、CLK(串行时钟)、SI/MOSI(主出从入)、SO/MISO(主入从出)、WP(写保护)、HOLD(暂停)、VCC、GND,以及底部焊盘用于散热与接地。实际引脚分配请以官方数据手册为准。

四、设计建议与注意事项

  • 电源去耦:VCC 旁放置 0.1 μF 陶瓷电容及 1 μF 至 10 μF 的滤波电容以抑制瞬态噪声。
  • PCB 布局:尽量缩短时钟与数据信号走线,保持差分串扰低,底部焊盘焊接良好以利散热与接地。
  • 片选管理:未使用时将 CS 拉高,避免总线冲突;WP 与 HOLD 可按需拉高以解除写保护/暂停。
  • ESD 与安全:在高静电环境下应采取相应保护,设计时考虑防护电阻或 TVS 二极管。
  • 温漂与老化:长期高温环境会加速寿命衰减,务必在规格范围内使用并做好系统级备份。

五、典型应用场景

  • 嵌入式系统固件/引导程序存储
  • 消费电子设备(机顶盒、智能家电)固件与资源存储
  • 物联网终端与传感器网关的数据记录与配置存储
  • 工业控制器与测量设备的非易失性存储

六、可靠性与寿命说明

器件擦写寿命达 100,000 次,单页编程典型时间 2.4 ms,数据在典型条件下可保留 20 年。对于关键数据建议采用磨损均衡、周期性备份与校验机制以延长系统可用性与数据完整性。

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
