FT24C02A-KLR-T 2Kbit I2C接口EEPROM产品概述

一、产品核心定位与基本属性

FT24C02A-KLR-T是辉芒微(FMD)推出的小容量非易失性EEPROM,主打「高可靠性、小封装、宽适配」特性,针对嵌入式系统、消费电子等领域的低容量参数存储需求设计。产品核心容量为2Kbit(即256字节),采用SOT-23-5超小封装,支持1.8V~5.5V宽电压范围与工业级温度范围,是替代传统小容量EEPROM的高性价比方案。

二、关键性能参数详解

2.1 存储与接口特性

  • 容量与接口:2Kbit非易失性存储(断电数据不丢失),采用I2C双向串行接口,兼容标准模式(100kHz)、快速模式(400kHz)与高速模式(1MHz),可与主流MCU(如STM32、51单片机)的I2C端口直接对接;
  • 地址扩展:通过A0引脚(SOT-23-5封装中可配置)支持多设备级联,最多可扩展8个同型号器件,满足多参数同步存储需求。

2.2 电气与可靠性参数

  • 工作电压:1.8V~5.5V宽范围,适配3.3V低功耗MCU(如STM32L系列)、5V传统单片机(如89C51)等不同平台;
  • 写周期效率:单次写周期时间≤5ms,支持8字节页写功能(单次写入最多8字节,减少写操作次数,提升效率);
  • 寿命与保留:写周期寿命达100万次(满足频繁参数更新),断电后数据保留时间≥100年;
  • 温度范围:工作温度-40℃~+85℃(工业级),可适应户外、工业现场等复杂环境。

三、封装与引脚功能

FT24C02A-KLR-T采用SOT-23-5封装,尺寸仅为2.9mm×1.6mm×1.1mm,大幅节省PCB布局空间,适合小型化产品(如贴片传感器、智能穿戴模块)。引脚功能定义如下:

引脚编号 功能描述 备注 1 GND 电源地 2 SDA I2C数据线(开漏输出) 3 WP 写保护输入(高电平有效) 4 SCL I2C时钟线(输入) 5 VCC 电源输入(1.8V~5.5V)

其中WP引脚为硬件写保护:当WP接高电平时,器件禁止写操作,仅允许读数据,可有效防止误写导致的参数丢失。

四、典型应用场景

FT24C02A-KLR-T的小容量、高可靠特性,使其适用于以下场景:

  1. 小型嵌入式系统:MCU周边参数存储(如传感器校准值、设备ID、固件版本);
  2. 消费电子:智能手环/手表(用户设置、运动数据缓存)、蓝牙耳机(配对信息、音频参数)、电视遥控器(自定义按键映射);
  3. 工业控制:小型传感器节点(环境监测的温度/湿度校准值)、电机控制模块(转速阈值、PID参数);
  4. 家电领域:加湿器(湿度阈值设置)、智能插座(定时参数)、小型风扇(风速档位记忆)。

五、产品优势总结

  1. 宽适配性:1.8V5.5V电压覆盖主流MCU,-40℃+85℃工业级温度适应复杂场景;
  2. 小封装高集成:SOT-23-5超小尺寸,满足小型化产品的空间需求;
  3. 可靠存储:100万次写寿命+100年数据保留,长期稳定存储关键参数;
  4. 高效通信:1MHz高速I2C+8字节页写,提升数据写入效率;
  5. 数据安全:硬件写保护(WP引脚)防止误写,保障参数不丢失。

FT24C02A-KLR-T凭借平衡的性能与成本优势,成为小容量EEPROM市场的实用选择,可广泛替代AT24C02等同类产品,适用于各类需要低容量非易失存储的电子设备。

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
