AT24C02M/TR(HGSEMI 华冠)产品概述(停产)

一、产品简介

AT24C02M/TR 为 HGSEMI(华冠)出品的一款 2Kbit 串行 EEPROM,采用标准 I2C 接口并提供 SOP-8 封装。此型号已被宣布停产,用于提示现有设计和库存管理需要尽快评估替代方案或采购补货。该器件面向低速数据存储、配置保存与参数记录等嵌入式应用场景。

二、主要参数

  • 接口类型:I2C(兼容常见主控总线)
  • 存储容量:2Kbit(256 字节)
  • 时钟频率(fc):最高 1MHz(快速模式/增强速率)
  • 写周期时间(Tw):典型 5ms(页写完成时间)
  • 数据保留(TDR):100 年
  • 写周期寿命:100 万次(耐久)
  • 工作电压:1.7V ~ 5.5V(宽电压范围,适配单/双电源系统)
  • 工作温度:-40℃ ~ +85℃(工业级)
  • 封装:SOP-8

三、功能特性

  • 噪声抑制功能:内置 EMI/噪声抑制设计,提高 I2C 总线在工业环境下的可靠性。
  • 硬件写保护(WP):提供物理 WP 引脚,可在硬件层面防止误写入或篡改。
  • 页写保护功能:支持页写保护策略,便于控制改写粒度与保护关键数据。
  • 宽电压与工业温度:适用于电池供电与多种工业应用。

四、封装与系统集成要点

SOP-8 封装便于传统通孔与贴片混合生产线采用,WP 引脚通常可直接接至板上拨码或 MCU 控制口以实现动态写保护。设计迁移时需注意页面大小、地址引脚配置(A0-A2)与时序匹配,以保证软件层兼容性。

五、典型应用

  • 系统参数与校准值保存
  • 产品序列号、配置寄存器存储
  • 物联网终端与传感器节点配置保持
  • 工业控制器与消费类电子的非易失性存储

六、停产影响与建议

AT24C02M/TR 停产后,建议采取以下措施:

  1. 评估现有库存并进行必要的末单采购(LTD)。
  2. 在设计上预留兼容替代件的封装与电气接口(尤其是 WP 与地址引脚),选用行业通用的 24C02 系列替代品。
  3. 替代件选择时,优先匹配工作电压范围(1.7~5.5V)、写周期时间、耐久性(1M 次)与数据保留规范,确认页大小与 I2C 时序兼容性。
  4. 与供应商或华冠代表沟通获取停产替代方案或生命周期支持信息。

若需,我可以基于您当前的原理图和软件驱动,推荐若干可直接替换的替代型号及必要的软硬件兼容调整建议。

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.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
