HG24C02CM/TR 产品概述

一、产品简介

HG24C02CM/TR 是华冠(HGSEMI)推出的一款低功耗、非易失性 I²C EEPROM,容量为 2Kbit。器件采用 SOP-8 封装,提供卷带(TR)包装,适配自动贴片生产线。器件面向工业级和消费类应用,兼顾耐久性与长期数据保持能力,适用于存储校准参数、设备配置、序列号和小型历史记录等场景。

二、主要规格

  • 接口类型:I²C(兼容标准 I²C/SMBus,最高时钟频率 fc = 1 MHz,支持 Fast-mode Plus)
  • 存储容量:2 Kbit(组织形式常见为 256 × 8,用户可按字节寻址)
  • 工作电压:1.7 V ~ 5.5 V,宽电压范围便于与多种 MCU/系统直接接口
  • 写周期时间(Tw):典型 3 ms(每次写操作完成前需等待写完成)
  • 数据保留(TDR):200 年(典型值)
  • 写周期寿命:2,000,000 次
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 封装:SOP-8;TR = Tape & Reel,便于 SMT 贴装加工

三、功能与特性

  • 标准 I²C 总线通信,单线地址与数据传输,接口简单易用
  • 支持常见 EEPROM 操作模式:随机读、顺序读及写入(请在系统设计中遵循器件时序和写周期要求)
  • 低电压工作能力,适合 1.8V/3.3V/5V 系统间的互联
  • 高耐久与超长数据保持,适合需长期保存配置参数或校准数据的应用
  • 封装与包装形式满足量产需求

四、可靠性与寿命说明

HG24C02CM/TR 在规格上提供 200 万次写入寿命和 200 年数据保持期,这是面向长寿命产品和重要参数长期保存的有力保障。典型写入周期为 3 ms,设计时应在写操作后等待写完成(或通过器件的应答判断写入是否完成),以避免数据损坏。器件工作温度范围 -40 ℃ 到 +105 ℃,可用于多数工业环境与恶劣工作条件下。

五、典型应用

  • 工业控制器与仪表的参数/配置保存
  • 消费类电子的出厂校准数据、序列号与设置存储
  • 嵌入式系统的固件外设参数与用户偏好
  • 智能家电、测量设备以及物联网设备的小容量非易失性存储

六、设计与使用建议

  • I²C 总线需要在 SCL/SDA 上配备合适阻值的上拉电阻;上拉值取决于总线容量与时钟频率,1 MHz 工作时需注意上拉和走线阻抗以保证信号完整性
  • 写操作后应遵循 Tw=3 ms 的写周期,或通过读取 ACK 判断写完成,避免在未完成写周期时对同一地址重复写入
  • 在电源管理与系统上电/掉电设计时,保证 VCC 在合法范围内升降,避免在未稳定供电时进行写操作
  • 量产采购时请注意 TR 表示带卷装,便于 SMT 自动化装配;SOP-8 封装在空间受限但需引脚方便焊接的场合具有优势

总结:HG24C02CM/TR 以其宽电压、工业温度、长寿命与高数据保持特性,适合对可靠性与长期保存有较高要求的系统。根据具体应用场景,结合 I²C 总线设计与写周期管理,可获得稳定可靠的长期存储解决方案。若需针对此器件的封装引脚图、时序图或参考电路,可提供进一步资料。

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
