ZD25WQ16CTIGT 产品概述

ZD25WQ16CTIGT 是 Zetta(澜智)推出的一款高性能 SPI NOR Flash 存储器,容量 16Mbit(2MByte),工作电压范围宽(1.65V ~ 3.6V),支持高达 104MHz 的 SPI 时钟,采用 SOP-8 150mil 封装并以 Tape & Reel 形式供货。该器件在低功耗、可靠性和数据保护方面有良好设计,适用于各种嵌入式、消费类及工业级应用。

一、主要特性概述

  • 存储容量:16Mbit(2MByte)
  • 接口类型:SPI(Serial Peripheral Interface)
  • 最高时钟频率(fc):104MHz,支持高速数据传输
  • 工作电压:1.65V ~ 3.6V,兼容低压与 3.3V 系统
  • 待机电流:典型 12µA(低待机功耗)
  • 擦写寿命:100,000 次(典型块擦写耐久)
  • 数据保留(TDR):20 年
  • 页写入时间(Tpp):1.8ms(典型)
  • 块擦除时间(tBE):12ms @ 32KB(典型)
  • 功能保护:硬件写保护、绝对写保护、写使能锁存(WEL)、软件写保护
  • 封装:SOP-8 150mil,Tape & Reel 贴片包装

二、功能与数据保护机制

ZD25WQ16CTIGT 提供多层次的写保护和数据安全功能,适合对闪存数据完整性和防误写要求较高的系统:

  • 硬件写保护(WP#):外部引脚控制,能在硬件层面禁止写入操作,适用于需要物理防护的设计场景;
  • 绝对写保护:在特定器件状态或引脚配置下实施更严格的不可改写保护,防止固件或关键数据被意外擦写;
  • 写使能锁存(WEL):遵循典型 SPI Flash 写入流程,需要先发送写使能命令,再进行编程或擦除操作;
  • 软件写保护:通过状态寄存器位设置,实现灵活的区块或全片写保护策略。

以上保护功能共同为关键代码与数据提供多层安全防护,便于在系统设计中实现可靠的固件管理。

三、性能与功耗

  • 104MHz 的 SPI 时钟支持快速读取与编程操作,能够满足系统对启动时间或数据流速的要求;
  • 低待机电流(约 12µA)有利于电池供电和低功耗设备,减少系统休眠时的能耗;
  • 快速写入与擦除性能(页面写入 1.8ms,32KB 擦除 12ms)在固件更新与数据日志管理场景下能提供较好的响应时间。

注意:具体时序和功耗数据请参考器件详细数据手册,不同操作模式与环境温度会影响实际性能。

四、可靠性与寿命

ZD25WQ16CTIGT 的擦写耐久度达到 100k 次,数据保存能力为 20 年(TDR),适用于需要长期存储固件、校准数据和配置信息的产品设计。该器件适合在工业环境中使用,但在极端温度或高写次数应用中应在系统架构级别进行可靠性评估与磨损均衡(wear leveling)策略设计。

五、封装与 PCB 设计注意事项

  • 封装:SOP-8 150mil,适合常规贴片生产工艺,便于插座替换与手板测试;
  • 供货:Tape & Reel,支持自动贴片与批量生产;
  • PCB 布局建议:布局时靠近 VCC 引脚放置去耦电容(如 0.1µF),确保 SPI 信号线短且阻抗匹配;WP# 与 HOLD#(如器件提供)应考虑上拉/下拉电阻与 EMI 影响;在高速模式下应注意信号完整性与 CMOS 输入保护。

六、典型应用场景

ZD25WQ16CTIGT 适用于多种需要中等容量非易失存储的应用,包括但不限于:

  • 嵌入式控制器与 MCU 固件存储(系统启动代码、Bootloader)
  • 物联网设备与传感器节点(固件更新、配置数据)
  • 消费类电子(家电、机顶盒、智能配件)
  • 工业控制与数据记录(参数存储、校准数据)
  • 网络通信设备(配置与日志存储)

总结 ZD25WQ16CTIGT 以其 16Mbit 容量、104MHz SPI 性能、宽电压范围与多重写保护功能,为要求可靠数据保存与高效固件管理的系统提供了一个兼具性能与稳定性的 NOR Flash 解决方案。详细引脚定义、命令集、时序和热性能等参数请参见 Zetta(澜智)官方数据手册,以获得完整的设计与实现指导。若需样片、技术资料或应用建议,请联系供应商或厂商技术支持。

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
