24FC01T-I/OT 产品概述

一、主要特性

24FC01T-I/OT 是来自 MICROCHIP(美国微芯)的一款小容量串行 EEPROM,采用 I2C 两线接口,存储容量为 1Kbit(128 字节),支持最高 1MHz 时钟频率。工作电压范围宽(1.7V 至 5.5V),适配多种供电方案;工作温度范围为 -40℃ 至 +85℃,满足工业级环境要求。

二、规格参数

  • 接口类型:I2C(两线串行总线)
  • 存储容量:1Kbit(128 字节)
  • 时钟频率(fc):最高 1MHz(Fast Mode Plus)
  • 工作电压:1.7V ~ 5.5V
  • 写周期时间(Tw):典型 5ms(完成内部写入周期)
  • 数据保留(TDR):200 年(典型)
  • 写周期寿命:100万次(耐写次数)
  • 工作温度:-40℃ ~ +85℃
  • 品牌:MICROCHIP(美国微芯)
  • 封装:SOT-23-5(小型化封装)

三、产品优势

  1. 宽电压兼容:1.7V~5.5V 的工作电压范围,可与低功耗 MCU 和传统 5V 逻辑直接兼容,便于系统集成。
  2. 高可靠性:数据保留长达 200 年,写入寿命高达 100 万次,适合需要长期可靠保存与频繁更新的配置与校准数据。
  3. 小体积封装:SOT-23-5 小型封装节省 PCB 空间,适合尺寸受限的消费类、便携式设备及 IoT 终端。
  4. 快速接口:支持 1MHz 时钟,能够在高速总线环境下实现快速读取,提升系统响应能力。

四、典型应用场景

  • 设备序列号、校准常数与参数存储
  • 启动加载配置与固件版本记录
  • 小量表格、查表数据及用户设置存储
  • 物联网终端、传感器模块、消费电子及工控设备中需要少量非易失性存储的场合

五、设计与使用建议

  • I2C 总线:为保证可靠通信,建议在 SDA、SCL 上配置适当阻值的上拉电阻;在总线较长或多设备环境下,根据电容调整上拉阻值以匹配 1MHz 工作频率。
  • 写入管理:采用页面写或批量写入策略可以减少写周期次数与总线占用;写操作后等待 Tw(约 5ms)以确保内部写入完成,也可通过器件的 ACK polling 技术判断写完成状态。
  • 电源与复位:尽量避免在写周期中断电,以防写入不完整;在系统有写保护引脚(WP)时根据需要使用,以防误写。
  • 封装焊接:SOT-23-5 为常见小封装,注意焊接工艺以避免过热导致封装应力或引脚损伤。

六、结论

24FC01T-I/OT 凭借 MICROCHIP 的工艺保证,在小容量、低电压、宽温度和高可靠性之间取得良好平衡。其小尺寸、长寿命和高兼容性,使之成为存储设备配置信息、校准数据与少量非易失性信息的理想选择。对于需要稳定、耐用且占位小的 EEPROM 方案的设计,24FC01T-I/OT 提供了实用且经济的解决路径。

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
