24LC04BT-E/OT 产品概述

一、主要规格

  • 接口类型:I2C(支持标准/快速模式,最大时钟频率 fc = 400 kHz)
  • 存储容量:4 Kbit(512 字节)
  • 工作电压:2.5 V ~ 5.5 V
  • 写周期时间(Tw):5 ms(典型写入完成所需时间)
  • 数据保持(TDR):200 年
  • 擦写/写周期寿命:1,000,000 次
  • 工作温度:-40 ℃ ~ +125 ℃
  • 品牌:MICROCHIP(美国微芯)
  • 封装:SOT-23-5

二、主要特性与优势

24LC04BT-E/OT 为工业级非易失性串行 EEPROM,具有宽工作电压范围(2.5 V–5.5 V)和宽温度范围(-40 ℃–+125 ℃),适合多种系统电源与恶劣环境。I2C 总线接口便于与微控制器、传感器及外围设备集成,支持最高 400 kHz 的通信速率。高耐久性(百万次写周期)和极长的数据保持期(200 年)使其在需要长期可靠存储的场合具有明显优势。SOT-23-5 小封装利于空间受限的 PCB 布局。

三、典型应用场景

  • 工业控制与数据记录:存储校准参数、设备配置和累计数据
  • 通信终端与消费电子:设备标识、固件配置参数保存
  • 物联网与传感节点:低功耗环境下的小容量参数存储
  • 汽车电子(符合高温要求的系统):非关键参数或配置数据保存

四、设计与使用建议

  • I2C 总线需要外部上拉电阻,建议根据总线容量和速率选择合适阻值以保证信号完整性。
  • 写操作时应考虑 Tw(5 ms),避免在写周期内启动冲突访问;对频繁写入的数据可采用缓存与批量写入以延长寿命。
  • 供电端建议加旁路电容以抑制瞬态噪声,确保在 2.5 V~5.5 V 范围内稳定工作。
  • 在选型与布局时注意 SOT-23-5 封装的热与焊盘要求,便于可靠焊接和散热。

五、封装与采购信息

此器件由 MICROCHIP(美国微芯)提供,常见封装为 SOT-23-5,适用于小型化和空间受限设计。选型时建议参考厂商数据手册获取引脚分配、时序图和完整电气特性,以便做出准确的系统集成与可靠性评估。

总结:24LC04BT-E/OT 是一款面向工业级应用的 4Kbit I2C EEPROM,具有宽电压、宽温度、高可靠性的特性,适合用于需要长期保存配置和校准数据的场景。

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
