FT24C128A-ESR-T EEPROM产品概述

FT24C128A-ESR-T是辉芒微(FMD)推出的一款串行电可擦除可编程只读存储器(EEPROM),采用标准I2C接口设计,以高可靠性、宽适配性、长寿命为核心特点,广泛适用于工业控制、消费电子、物联网等多领域的非易失性数据存储需求。

一、产品基本信息

该型号属于FT24C系列EEPROM,存储容量为128Kbit(换算为16KB字节),可满足中小规模数据(如设备配置、校准参数、用户设置等)的长期保存需求。作为串行存储器件,其I2C接口无需复杂地址总线,仅需两根信号线即可实现数据交互,大幅简化电路设计与布线成本。

二、核心性能参数

FT24C128A-ESR-T的性能参数针对实际应用场景优化,关键指标清晰明确:

  • 存储容量:128Kbit(16KB),支持按字节/页写入,页大小符合I2C EEPROM标准,单次页写可覆盖多字节数据;
  • 接口与速率:标准I2C串行接口,最高时钟频率达1MHz,兼容100kHz/400kHz低速I2C设备,数据传输效率高;
  • 电压范围:1.8V~5.5V宽电压覆盖,适配低功耗电池供电系统(如IoT节点)及常规5V电源设备,无需额外电平转换;
  • 写操作特性:单次写周期时间(Tw)仅5ms,写周期寿命达100万次,远高于行业常规EEPROM的10万次标准,适合频繁更新配置的场景;
  • 数据可靠性:数据保留时间(TDR)达100年,即使长期不通电也能稳定保存关键数据;
  • 温度范围:-40℃~+85℃工业级工作温度,可适应户外、车间等恶劣环境。

三、封装与集成特性

FT24C128A-ESR-T采用SOP-8(小外形8引脚)封装,尺寸紧凑(典型尺寸:5.2mm×6.0mm),适合小型化电路设计(如贴片PCB、嵌入式模块)。引脚配置符合I2C EEPROM标准:

  • 核心引脚:SDA(串行数据线)、SCL(串行时钟线);
  • 地址引脚:A0/A1/A2(最多支持8片级联,扩展存储容量);
  • 保护引脚:WP(写保护,防止误写);
  • 电源引脚:VCC(电源)、GND(地)。

电路集成无需额外设计,直接对接微控制器I2C总线即可,上手成本低。

四、典型应用场景

基于宽电压、工业级温度及高写寿命等特性,该产品适用于以下场景:

  1. 工业控制领域:PLC模块、传感器节点的校准参数、设备配置信息存储,适应-40℃~+85℃的车间/户外环境;
  2. 物联网(IoT)节点:电池供电的智能传感器、无线模块的状态数据、低功耗配置存储(1.8V适配3.7V锂电池降压需求);
  3. 消费电子:智能家居设备(如智能插座、温控器)、小型家电的用户设置、固件参数备份;
  4. 通信设备:小型路由器、交换机的MAC地址、网络配置信息存储,高写寿命支持频繁配置更新;
  5. 汽车电子(辅助):车载低功耗模块(如胎压监测接收器)的校准数据存储,适配车载12V电源系统(经降压后可稳定工作)。

五、选型对比优势

与同容量常规EEPROM相比,FT24C128A-ESR-T具有明显竞争力:

  • 写寿命提升10倍:100万次写周期,解决了常规EEPROM频繁写易失效的问题;
  • 宽电压无转换:1.8V~5.5V覆盖,兼容更多电源系统,降低BOM成本;
  • 工业级可靠性:-40℃~+85℃温度范围+100年数据保留,满足 harsh环境需求;
  • 快速写周期:5ms/次,缩短数据存储等待时间,提升系统响应速度。

综上,FT24C128A-ESR-T以高可靠性、宽适配性、低成本集成等特点,成为中小容量非易失性存储的优选器件,可满足多领域的实际应用需求。

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
