ZD25WQ80CTIGT 产品概述
一、产品简介
ZD25WQ80CTIGT 是澜智（Zetta）推出的一款 SPI NOR FLASH 存储器，容量 8Mbit（1 MByte），器件版本 VerC。器件采用标准 SOP8-150mil 封装，面向工业与消费类嵌入式系统的代码存储、参数保存与固件升级等场景设计，兼顾低功耗与高速访问。
二、主要规格与性能
- 接口类型：SPI（标准串行外设接口）
- 存储容量：8Mbit（1 MByte）
- 最大时钟频率（fc）：104 MHz
- 工作电压：1.65 V ~ 3.6 V
- 待机电流：典型 1.3 μA（低功耗待机）
- 页写入时间（Tpp）：典型 1.5 ms（单页编程）
- 擦写寿命：100,000 次（典型）
- 数据保留（TDR）：20 年
三、关键特性
- 硬件写保护（WP 引脚支持）
- 绝对写保护（可实现对全部或部分区块的永久保护）
- 写使能锁存（WEL）机制，避免误写入
- 软件写保护（可通过软件命令配置保护区）
- 上电复位（POR）保证上电有序初始化，避免总线误动作
四、典型应用场景
- MCU/MPU 的固件与引导存储（Boot ROM）
- 工业控制器的配置及日志保存
- 消费类电子产品的固件升级存储
- 通信设备与智能模组的参数与校准数据保存
五、封装与系统集成建议
- 封装：SOP8 150 mil，适配常见 DIP/SOP PCB 布局，便于手工焊接与量产贴片。
- 电源与去耦：在 VCC 引脚附近放置 0.1 μF 陶瓷去耦电容，减小电源纹波对时序的影响。
- 时序与擦写管理：编程前需先发送写使能命令并等待 Tpp 完成；对频繁写入的数据建议做磨损均衡与擦写次数管理以延长寿命。
- 写保护策略：建议在生产与固件更新流程中结合硬件 WP 与软件写保护，实现对关键区块的多层防护。
六、注意事项
- 确认工作电压与系统电源匹配，避免超出器件额定范围。
- 在高频 SPI 工作下注意 PCB 布线长度与阻抗匹配，必要时加上系列终端电阻。
- 在设计固件升级与擦写方案时考虑数据保留（20 年）与擦写寿命（100k 次），合理分配存储区。
ZD25WQ80CTIGT 以其低功耗、可靠的写保护机制和稳定的存储性能，适合对数据完整性与长期可靠性有较高要求的嵌入式系统。若需引脚定义、指令集和典型电路图，请参阅器件详细数据手册。

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.
