ZD25WD20CFIGR 产品概述
一、产品简介
ZD25WD20CFIGR 是澜智（Zetta）推出的一款性能优异的 SPI NOR Flash 存储器，容量 2Mbit（256KByte），支持最高 104 MHz 时钟频率。器件工作电压范围宽（1.65V 至 3.6V），适配多种电源方案，并以超小型 DFN6（USON-6）封装（1.2 × 0.7 × 0.45 mm）提供，适合空间受限的便携与嵌入式应用，出厂采用 Tape & Reel 卷带包装，便于贴片组装。
二、主要电气与性能参数
- 接口类型：标准 SPI（高速读取支持 104 MHz）
- 存储容量：2 Mbit（256 KByte）
- 工作电压：1.65 V ~ 3.6 V（支持单节锂电池及 3.3V 系统）
- 待机电流：典型 0.5 μA（低功耗待机）
- 擦写寿命：100,000 次（典型）
- 数据保持：TDR 20 年
- 页写入时间（Tpp）：典型 2 ms
- 块擦除时间（tBE）：典型 13 ms
三、功能特性
- 写使能锁存（Write Enable Latch），确保写操作受控执行
- 软件写保护（Software Write Protect），灵活保护重要数据区
- 上电复位（Power-On Reset），确保上电后设备进入确定状态
这些功能配合标准 SPI 指令集，便于固件控制与系统集成。
四、封装与可靠性
器件采用 DFN6（USON-6）超薄小封装（尺寸 1.2×0.7×0.45 mm），适合手机模块、穿戴设备、无线传感器等对体积要求严格的场合。高擦写寿命与长期数据保持能力，使其在工业与消费类产品中均能提供可靠的存储保障。
五、典型应用场景
- 引导固件（Bootloader）与系统配置存储
- 配置数据与参数保存（Calibration、MAC、序列号）
- 可编程逻辑的固件更新与补丁存储
- 物联网终端、蓝牙/Wi‑Fi 模块、可穿戴设备、便携式电子产品
六、设计与使用建议
- 布局时靠近 MCU 的 SPI 引脚放置，缩短走线，降低干扰与延迟
- 在 VCC 引脚附近添加 0.1 μF 陶瓷去耦电容以稳定电源
- 写入/擦除操作期间尽量避免频繁的电源波动，使用上电复位功能确保稳定启动
- 合理配置软件写保护区域，重要参数建议多重备份
ZD25WD20CFIGR 以其低功耗、宽电压范围、高可靠性和超小封装，为空间受限且对数据可靠性有较高要求的产品提供了理想的非易失性存储解决方案。如需详细指令集、时序图或参考设计，请联系澜智（Zetta）或查阅产品技术手册。

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.
