FT24C02A-KSR-B EEPROM产品概述

一、产品核心身份与定位

FT24C02A-KSR-B是辉芒微(FMD) 推出的串行电可擦除可编程只读存储器(EEPROM),采用I2C接口设计,以2Kbit(256字节)存储容量为核心,定位为小体积、高可靠、宽适配的通用存储器件,广泛适用于消费电子、工业控制、物联网等领域的低功耗、小型化产品。

二、关键技术参数深度解析

FT24C02A-KSR-B的参数围绕“易用性、可靠性、适配性”展开,核心特性如下:

2.1 存储与接口特性

  • 存储容量:2Kbit(256字节),采用8位字节寻址,适合存储少量关键数据(如配置参数、校准值、身份标识等);
  • 接口类型:标准I2C串行接口,仅需SDA(数据线)、SCL(时钟线)2根信号线,兼容标准模式(100kHz) 和快速模式(1MHz),可与主流MCU(STM32、51单片机、低功耗MCU)直接通信,无需额外电平转换;
  • 地址扩展:支持3位硬件地址引脚(A0/A1/A2),最多可在同一I2C总线挂载8片,总存储容量扩展至16Kbit。

2.2 电气与可靠性参数

  • 工作电压:1.8V~5.5V宽电压范围,兼容3.3V、5V系统,适配电池供电(1.8V低功耗设备)、市电供电等场景;
  • 写周期性能:单字节写入时间(Tw)≤5ms,支持页写入(最大16字节),批量写入效率更高;
  • 寿命与数据保留:写周期寿命达100万次,满足长期反复写入需求;数据保留时间(TDR)≥100年,断电多年仍可完整读取;
  • 温宽范围:工作温度-40℃~+85℃,符合工业级标准,适应户外、车载辅助系统等恶劣环境。

三、封装形式与引脚说明

FT24C02A-KSR-B采用SOP-8贴片封装,尺寸约5.2mm×4.0mm×1.6mm,脚距1.27mm,适配常规贴片工艺,引脚功能如下:

引脚编号 引脚名称 功能说明 1 A0 硬件地址引脚0(上拉/下拉设置) 2 A1 硬件地址引脚1 3 A2 硬件地址引脚2 4 GND 电源地 5 SDA I2C数据线(开漏输出) 6 SCL I2C时钟线(开漏输出) 7 WP 写保护引脚(高电平:写保护;低电平:允许写入) 8 VCC 电源正极

注:WP引脚悬空默认“允许写入”,建议外接电阻实现写保护。

四、典型应用场景

FT24C02A-KSR-B的参数特性适配多场景,核心应用包括:

4.1 消费电子领域

  • 智能穿戴:手环、手表的步数校准、佩戴模式存储;
  • 智能家居:智能插座、温湿度传感器的校准偏移、定时配置存储;
  • 便携设备:蓝牙耳机的配对信息、音量默认值存储。

4.2 工业控制领域

  • 电机驱动:伺服/步进电机的额定参数、故障记录存储;
  • PLC与传感器:PLC的I/O配置、工业传感器的校准数据存储;
  • 电源模块:开关电源的输出电压校准、保护阈值存储。

4.3 物联网与低功耗场景

  • 传感器节点:环境监测节点的身份ID、采样间隔配置存储;
  • 电池供电设备:低功耗MCU的唤醒阈值、参数备份存储。

五、核心性能优势总结

FT24C02A-KSR-B相比同类产品,具备以下优势:

  1. 宽电压适配:1.8V~5.5V覆盖主流MCU供电,简化设计;
  2. 高可靠性:100万次写寿命+100年数据保留,长期稳定;
  3. 小体积集成:SOP-8封装节省PCB空间,适合小型化产品;
  4. 便捷接口:I2C仅需2线,布线简单,易集成;
  5. 工业级温宽:-40℃~+85℃适应恶劣环境,扩展应用场景。

该产品以平衡的性能与成本优势,成为中小容量存储需求的主流选择。

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
