  • 工作电压:1.7V ~ 5.5V(宽电压范围,兼容 1.8V、3.3V、5V 系统)
  • 工作温度:-40°C ~ +105°C(工业级)
  • 数据保持时间(TDR):200 年
  • 写周期寿命:2,000,000 次(写耐久)
  • 单次写入周期时间(Tw):3 ms(典型写入完成时间)
  • 封装:SOP-8
  • 品牌:HGSEMI(华冠)

三、关键特性

  1. 宽电压工作:1.7V 到 5.5V 的输入电压范围,便于与不同电源电平系统直接接口。
  2. 高可靠性存储:数据保留达 200 年,写入耐久高达 200 万次,适合对数据完整性要求高的场景。
  3. 高速 I2C 通信:支持最高 1MHz 时钟频率,满足对通信带宽有要求的系统。
  4. 低功耗与小封装:SOP-8 封装占用空间小,适合板级设计与空间受限场合。
  5. 快速写周期:单次写入完成时间约 3 ms,有利于提高系统响应与数据更新效率。

四、可靠性与质量

AT24C64CM/TR 在设计上侧重长期稳定性与工业级可靠性。200 年的数据保持以及 200 万次写循环说明其在非易失性数据保存方面具备优异性能,适用于计量、配置存储、日志记录等需长时间保留数据的应用。器件工作温度覆盖 -40°C 至 +105°C,满足户外、工业等极端环境使用需求。

五、典型应用场景

  • 工业控制器与仪表的配置参数存储
  • 消费电子(智能家电、遥控器、机顶盒)中的设置与序列号保存
  • 物联网终端的固件配置与校准数据保存
  • 汽车电子(非安全关键)中的历史日志与标识信息
  • 医疗设备、计量设备中的长期数据记录与备份

六、设计与使用建议

  1. 总线设计:在多器件共用 I2C 总线时,注意地址配置与上拉电阻选择,保证在 1MHz 通信下的信号完整性。
  2. 电源与上电时序:建议在上电与掉电过程中遵循器件数据手册的电源和 I/O 电平约束,避免在非稳定电压时进行写操作以防写入错误。
  3. 写入策略:鉴于写周期时间为 3 ms,批量写入时应考虑分页或分段写入,并在写完成后检查必要的确认机制以确保数据已写入。
  4. 数据保护:对关键配置信息建议采用校验或冗余机制,进一步提高数据可靠性。

七、封装与订购信息

  • 标准封装:SOP-8,适合常见 PCB 插装工艺
  • 品牌:HGSEMI(华冠)
  • 产品分类:未分类(根据具体采购渠道与型号后缀请向供应商确认具体版本与出厂标识)

八、结论

AT24C64CM/TR 是一款面向工业与商业应用的高可靠 I2C EEPROM,具备宽电压、工业级温度、超长数据保持和高写入寿命等优点。对于需要长期保存配置、日志或校准数据的产品,提供了稳定且易于集成的存储解决方案。购买与设计前建议参考华冠官方数据手册以获取完整时序、引脚及电气特性表格。

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
