ZD25WQ80CSIGT 产品概述

一、产品简介

ZD25WQ80CSIGT 是澜智(Zetta)推出的一款高性能 SPI NOR Flash 存储器,容量 8Mbit(1M 字节),工作电压范围宽(1.65V~3.6V),最高时钟频率可达 104MHz,封装为 SOP8-208mil。该器件面向对代码存储、配置数据和日志等需求的嵌入式与工业级应用,兼顾低功耗与高可靠性。

二、主要参数

  • 接口类型:SPI(支持标准/高速 SPI 模式)
  • 存储容量:8 Mbit
  • 最高时钟频率(fc):104 MHz
  • 工作电压:1.65V ~ 3.6V
  • 待机电流:1.3 μA(典型值)
  • 擦写寿命:100,000 次(典型)
  • 页写入时间(Tpp):1.5 ms
  • 块擦除时间(tBE):15 ms
  • 数据保留(TDR):20 年
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SOP8 208mil
  • 品牌:Zetta(澜智)

三、功能特性

  • 硬件写保护(WP 引脚)与绝对写保护功能,支持物理防误写
  • 写使能锁存(Write Enable Latch)机制,防止意外写入
  • 软件写保护(通过状态寄存器配置分区保护)
  • 上电复位(POR)保证上电期间可靠启动与稳定性 这些保护与控制机制适用于要求高数据完整性的系统设计。

四、性能与可靠性

ZD25WQ80CSIGT 在 104MHz 时钟下提供快速的读写响应,页编程时间 1.5ms、块擦除 15ms,满足大多数固件更新与数据记录场景。器件耐久性高,擦写寿命达 100k 次,数据保留保证 20 年,且在工业级温度范围内稳定工作,适合长周期部署的嵌入式系统。

五、封装与布局建议

标准 SOP8-208mil 封装便于 DIP 到 SMT 的板级适配,建议在布局时:

  • 在 VCC 旁放置 0.1μF 陶瓷去耦电容,靠近封装引脚
  • 为 WP、HOLD(如有)与 CS 等控制引脚预留可调跳线,以便应用中灵活配置保护策略
  • 注意 SPI 信号线长度与阻抗匹配以保证 104MHz 传输质量

六、典型应用场景

  • MCU 启动代码与引导加载:可靠存储引导固件
  • 工业控制与仪表:在严苛温度下保存配置信息
  • 物联网与便携终端:低功耗待机与快速读取
  • 消费电子与机顶盒:固件升级与用户设置保存

七、设计要点与注意事项

  • 电源管理:保证 VCC 在 1.65V~3.6V 范围内,避免欠压写入;上电需遵循 POR 时序
  • 写保护策略:系统设计时应结合硬件(WP)与软件(状态寄存器)保护,防止误写或越权擦写
  • 时序与时钟:在高频模式下确认 SPI 主机满足器件时序要求,并考虑信号完整性
  • 温度与寿命:在高循环写场景下评估擦写均衡(wear leveling)或外部存储映射策略以延长寿命

ZD25WQ80CSIGT 以其宽电压、低功耗与完整的写保护特性,适用于多种嵌入式和工业应用。选型时请参考澜智官方完整数据手册与器件时序表,结合系统需求进行 PCB 布局与电源设计,以确保长期稳定运行。

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
