FT24C02A-KTR-T 串行EEPROM产品概述

FT24C02A-KTR-T是辉芒微(FMD)推出的一款I2C接口串行EEPROM,专为小容量非易失性存储需求设计,具备宽电压适配、高速通信及工业级可靠性等核心特点,广泛适用于消费电子、工业控制及物联网等场景。

一、产品基本信息

  • 品牌型号:辉芒微(FMD)FT24C02A-KTR-T
  • 器件类型:电可擦除可编程只读存储器(EEPROM)
  • 核心定位:低功耗、小容量、高可靠性的串行存储器件

二、核心性能参数

该器件的关键参数覆盖存储、通信、可靠性及环境适应性,具体如下:

  1. 存储容量:2Kbit(等效256字节),满足小型参数、ID或状态数据的存储需求;
  2. 通信接口:标准I2C串行接口,支持最高1MHz时钟频率,比常规低速I2C(100kHz/400kHz)通信效率提升显著;
  3. 工作电压:1.8V~5.5V宽电压范围,可适配3.3V、5V主流MCU系统,以及1.8V低功耗设备;
  4. 写操作特性:单次写周期时间(Tw)为5ms,写周期寿命达100万次,数据保留时间(TDR)长达100年,确保长期存储无丢失;
  5. 工作环境:-40℃~+85℃工业级温度范围,可适应户外、车间等恶劣环境,抗温湿度波动能力强。

三、封装与引脚配置

FT24C02A-KTR-T采用TSSOP-8小封装(尺寸约3mm×4.4mm),引脚布局清晰,具体功能如下:

引脚编号 引脚名称 功能说明 1 A0 地址输入0(硬件配置) 2 A1 地址输入1(硬件配置) 3 A2 地址输入2(硬件配置) 4 VSS 电源地 5 SDA I2C串行数据总线(双向) 6 SCL I2C串行时钟总线(输入) 7 WP 写保护(高电平有效,禁止写入) 8 VCC 电源输入(1.8V~5.5V)

注:A0~A2通过上拉/下拉电阻可配置8种不同地址,支持最多8个器件并联在同一I2C总线,提升系统存储扩展性。

四、典型应用场景

FT24C02A-KTR-T的特性使其适用于以下场景:

  1. 消费电子:遥控器、小型家电(如加湿器、智能插座)的参数(定时、模式)存储;
  2. 工业控制:传感器节点的校准数据、设备ID、运行日志存储;
  3. 物联网设备:低功耗电池供电设备(如无线传感器)的配置信息存储;
  4. 通信模块:蓝牙、WiFi模块的配对信息、固件版本存储;
  5. 汽车辅助设备:车载小部件(如USB充电器、氛围灯)的状态记录(适配-40~85℃环境)。

五、关键优势特点

与同类器件相比,FT24C02A-KTR-T具备以下核心优势:

  1. 宽电压适配:1.8V~5.5V覆盖绝大多数MCU和系统电源,无需额外电平转换;
  2. 高速通信:1MHz I2C时钟支持快速数据读写,适合高吞吐量需求场景;
  3. 高可靠性:100万次写寿命+100年数据保留,满足长期稳定存储要求;
  4. 小封装设计:TSSOP-8封装体积小,适合紧凑PCB布局;
  5. 工业级温度:-40~85℃工作范围,适应恶劣环境,降低环境适配成本。

六、使用注意事项

为确保器件正常工作,需注意以下要点:

  1. 写保护管理:WP引脚需保持低电平(或接VSS)才能正常写入,高电平时禁止写入,避免误操作;
  2. 写周期等待:每次写入操作后需等待5ms(Tw),待写周期完成后再进行下一次写入,否则可能导致数据错误;
  3. 地址配置:A0~A2的硬件配置需与系统I2C地址规划一致,避免地址冲突;
  4. 电源稳定性:确保VCC电压在1.8V~5.5V范围内,避免电压波动(如瞬态尖峰)导致存储异常。

综上,FT24C02A-KTR-T是一款高性价比的串行EEPROM,凭借宽电压、高速、高可靠性及小封装等优势,可满足多种领域的小容量非易失性存储需求。

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
