AT24C02N 产品概述
一、产品简介
AT24C02N 是 HGSEMI（华冠）提供的一款低功耗、低电压的串行电可擦除可编程只读存储器（EEPROM）。标准容量为2Kbit（组织为256 × 8），同时系列还提供 4K、8K、16K（分别组织为512/1024/2048 × 8）等容量选项，采用紧凑的 8 引脚封装，通过两线 I2C 接口进行访问，适用于对非易失性配置、参数或小容量数据存储有严格功耗和体积要求的工业与商业产品。
二、主要规格
- 接口类型：I2C（双线串行接口）
- 存储容量：2Kbit（系列还包括 4K/8K/16K 可选）
- 组织形式：256 × 8（其它容量对应 512/1024/2048 × 8）
- 时钟频率（最大）：1 MHz
- 写周期时间（典型）：5 ms
- 数据保持（TDR）：100 年
- 写循环寿命：1,000,000 次
- 工作电压：1.7 V ~ 5.5 V（宽电压范围，兼容低压系统）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 封装形式：DIP-8（同时支持 SOP-8、MSOP-8、SOT-23-5 等）
三、功能亮点
- 硬件写保护：提供外部写保护引脚，可在需要时禁止写操作，增强数据安全性与系统可靠性。
- 噪声抑制：内置噪声抑制措施，提升总线抗干扰能力，适应工业环境下的电磁干扰条件。
- 低功耗与低电压支持：在 1.7 V 起即可工作，适合电池供电和便携式设备；低静态电流设计利于长时间待机。
- 长寿命与高可靠性：百万次写循环与百年数据保持，满足配置存储和长期数据日志保存的需求。
四、典型应用
- 工业控制设备、传感器模块的参数与校准数据保存
- 消费类电子产品的用户配置与系统设置存储
- 通信设备与网络设备的固件参数与 MAC/序列号存放
- 智能仪表、计量设备的数据日志与标定信息保存
- 物联网终端与低功耗嵌入式系统的配置信息存储
五、选型建议与注意事项
- 若系统需更大容量可选择 4K/8K/16K 型号，与主控地址映射和寻址方式保持一致。
- 在高噪声环境下建议配合合理的上拉电阻、滤波与 PCB 布局以充分发挥噪声抑制功能。
- 使用写保护功能时应明确控制策略，以避免因误操作造成数据丢失。
- 工作电压接近下限（1.7 V）时，请验证时序和通信稳定性，必要时进行系统级测试。
总结：AT24C02N（HGSEMI）以其宽电压、低功耗、高耐久性和硬件写保护等特性，成为工业和商业场景中常用的短程非易失性存储选择，尤其适合对可靠性和长期数据保存有严格要求的应用场合。

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.
