24LC1026-I/SN 产品概述

一、产品简介

24LC1026-I/SN 是美国微芯(Microchip)推出的一款串行 I2C EEPROM,容量为 1 Mbit(128 KByte),采用 SOIC-8 封装。器件兼容标准 I2C 总线,最高工作时钟频率可达 400 kHz,工作电压范围宽(2.5 V ~ 5.5 V),非常适合在多种电压域和嵌入式系统中作为非易失性数据存储器使用。

二、主要技术参数

  • 存储容量:1 Mbit(128 KByte)
  • 接口类型:I2C,总线速率最高 400 kHz(Fast-mode)
  • 工作电压:2.5 V ~ 5.5 V
  • 写周期时间(Tw):典型 5 ms(每次写入完成所需时间)
  • 写周期寿命:1,000,000 次
  • 数据保存(TDR):200 年(典型)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SOIC-8
  • 品牌:MICROCHIP(美国微芯)

三、关键特性与优势

  • 容量与兼容性兼顾:1 Mbit 大容量满足参数存储、固件偏好、日志等需求,同时兼容标准 I2C 协议,便于与 MCU、DSP、FPGA 等主控器互联。
  • 宽电压范围:2.5 V~5.5 V 使其可在 3.3 V 和 5 V 系统中直接使用,无需额外电平转换器。
  • 高可靠性:写入寿命高达 100 万次,数据保留时间长(典型 200 年),适合长期存储和多次写入场景。
  • 工业级温度范围:-40 ℃ 到 +85 ℃,适合工业、汽车电子及户外设备使用。

四、应用场景

  • 工业控制器:配置参数、校准数据、运行日志保存
  • 消费电子:用户设置、配置信息存储
  • 医疗设备与测试仪器:长时间保存校准和参数
  • 数据记录器与物联网终端:本地持久化储存传感器采样或事件记录

五、使用建议与设计要点

  • 写入管理:由于写周期约为 5 ms,建议采用页写(若采用页写方式可减少总线事务次数)和批量写入策略以提高效率,并在写操作后使用 ACK 轮询或等待写完成时间以确认写入完成。
  • ECC 与数据完整性:对于关键数据建议增加校验(CRC)或冗余存储,以应对异常断电或写入中断导致的数据不一致。
  • 电源与上电顺序:在系统设计时确保在写操作进行期间,供电稳定且不会发生复位或掉电,必要时可在关键写操作期间禁用外部复位或使用电源监测电路。
  • 总线设计:I2C 上拉电阻和布线长度会影响信号完整性,尤其在 400 kHz 速率下,推荐根据系统总线拓扑选择合适的上拉阻值并尽量缩短走线。

六、封装与采购信息

  • 封装形式:SOIC-8,便于标准化 PCB 布局与生产装配。
  • 型号示例:24LC1026-I/SN(请依据具体采购渠道确认完整的订货信息、包装方式与最低采购量)

七、可靠性与寿命说明

  • 写周期寿命:1,000,000 次(典型),适合频繁写入的应用场景
  • 数据保留:典型 200 年,适用于长期档案类存储
  • 温度稳定性:-40 ℃ 至 +85 ℃,满足工业级可靠性要求

总结:24LC1026-I/SN 以其 1 Mbit 大容量、宽电压范围、标准 I2C 接口和高可靠性,适合各类需要持久化存储的嵌入式与工业应用。在系统设计中应关注写入策略、电源完整性与总线布局,以发挥其最佳性能与可靠性。

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
