24AA02E48T-I/SN 产品概述

一、产品简介

24AA02E48T-I/SN 是 MICROCHIP(美国微芯)推出的一款低功耗、串行 I²C EEPROM,容量为 2Kbit(组织为 256 × 8)。器件支持标准 I²C 通讯,最高时钟频率达 400 kHz,工作电压宽(1.7 V ~ 5.5 V),适用于多种低电压与单电源系统。该系列以体积小、可靠性高、易集成为特点,常用于存储校准数据、配置参数、序列号及小容量非易失性数据。

二、主要规格

  • 存储容量:2Kbit(256 × 8)
  • 接口类型:I²C(最高 fc = 400 kHz)
  • 工作电压:1.7 V ~ 5.5 V
  • 写周期时间(Tw):典型 5 ms(写入后需等待内部写入完成)
  • 读出响应:参考型号备注中有 900 ns 级别的快速读出特性(以数据手册为准)
  • 数据保留(TDR):200 年(典型)
  • 写周期寿命:1,000,000 次(典型)
  • 工作温度:-40 ℃ ~ +85 ℃(工业级)
  • 封装:8-SOIC(便于 PCB 布局与替换)

三、功能与特性

  • I²C 串行总线兼容,支持主/从通信模式,易与 MCU、DSP、FPGA 等主控器件连接。
  • 宽电压范围支持 1.7 V 低电压供电,向下兼容多种电源架构。
  • 高可靠性:极长的数据保留期与高写入寿命,适合长期保存配置信息和标识数据。
  • 小体积封装(8-SOIC)便于在空间受限的应用中使用,并且与同类 8 引脚器件兼容性好,便于替换与布局标准化。
  • 型号后缀 E48 通常表明可用于存放 EUI‑48/唯一设备地址的方案,便于需要唯一标识的网络或资产管理应用(具体预置信息请以数据手册与出厂说明为准)。

四、典型应用场景

  • 工业控制与仪表:保存校准常数、运行参数与设备配置。
  • 网络与通信设备:存储MAC/EUI 地址、设备 ID 与配置参数。
  • 物联网与嵌入式终端:设备注册信息、标识码、固件配置表等小容量数据存储。
  • 消费电子与安全设备:保存用户参数、序列号与安全相关的小规模非易失性数据。

五、封装与硬件集成建议

  • 封装为 8‑引脚 SOIC,焊盘设计请参照 MICROCHIP 官方封装图纸以保证可靠焊接与散热。
  • I²C 总线需外接上拉电阻(按总线容量与速率选值),并在电源引脚附近放置去耦电容以抑制干扰。
  • 写入操作后需尊重写周期时间(Tw),在写入期间避免断电或频繁重写,以防数据损坏。
  • 在设计中预留设备地址与电气隔离方案(如需要在多器件系统中共享同一总线时),并参考数据手册确认页写大小与地址映射。

六、注意事项与选型提示

  • 虽然该器件具备长数据保留与高写寿命,仍应根据实际写入频率与工作环境评估寿命需求;频繁写入应用可考虑外部 wear‑leveling 或更大容量器件。
  • 型号中带有 E48 后缀的产品在出厂时可能含有预置唯一地址或序列信息,选型时确认出厂编程内容与可用存储地址范围。
  • 最终设计与关键参数(页写大小、设备地址细节、典型功耗与时序)请以 MICROCHIP 官方数据手册为准,完成电路验证后再进入量产。

综上,24AA02E48T-I/SN 提供了小容量、低电压、工业级温度范围与高可靠性的 EEPROM 解决方案,适合对容量要求不高但对可靠性与唯一设备标识有需求的各类嵌入式与联网产品。

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
