FT24C32A-ETR-T 产品概述

一、产品定位与核心身份

FT24C32A-ETR-T是辉芒微(FMD) 推出的32Kbit容量I2C接口电可擦除可编程只读存储器(EEPROM),属于FT24C系列非易失性存储器件。该器件采用TSSOP-8 薄型贴片封装,主打“高可靠性、宽适配性、高速通信”三大核心优势,主要面向工业控制、消费电子、智能家居等需要小容量非易失性存储的场景,可稳定存储配置参数、校准数据、设备ID等关键信息(掉电后数据不丢失)。

二、关键性能参数详解

FT24C32A-ETR-T的核心参数覆盖“存储容量、电压适配、通信速率、可靠性”四大维度,具体如下:

  1. 存储容量:32Kbit(换算为4096字节),支持字节/页写入读取,页大小为32字节(行业常规规格),页写可提升批量数据写入效率;
  2. 工作电压范围:1.8V~5.5V,覆盖低功耗嵌入式系统(如1.8V可穿戴设备)到传统5V单片机平台,无需额外电压转换;
  3. I2C时钟频率:最高1MHz(支持I2C Fast Mode),比标准100kHz模式快10倍,满足实时数据存储需求;
  4. 写周期特性:写周期时间(Tw)仅5ms(远快于同类10ms规格),单次写操作耗时短;写周期寿命达100万次,是消费级器件(10万次)的10倍,适合频繁修改数据场景;
  5. 数据保留与温度:数据保留时间(TDR)达100年(远超行业20年要求),长期不供电仍稳定存数;工作温度范围**-40℃~+85℃**,符合工业级环境要求,适应低温户外、高温设备内部等场景。

三、接口与通信特性

FT24C32A-ETR-T采用标准I2C两线制接口(SCL时钟线、SDA数据线),通信优势显著:

  1. 硬件寻址:支持A0/A1/A2引脚硬件地址配置,最多级联8片器件(2^3=8),适合多设备集中存储(如传感器网络);
  2. 读写模式:
    • 写操作:单字节写、页写(最多32字节),页写完成自动停止,无需软件干预;
    • 读操作:随机读(指定地址)、顺序读(连续读取至末尾),兼容STM32、51、AVR等主流单片机;
  3. 协议兼容:完全符合I2C Fast Mode标准,与其他I2C器件无缝协同,无需协议转换。

四、封装与应用场景

4.1 封装特性

采用TSSOP-8 封装,特点如下:

  • 体积小巧:尺寸约3.0mm×4.4mm,比DIP-8缩小60%以上,适合小型化设备;
  • 贴片安装:支持回流焊工艺,生产效率高,适合批量制造;
  • 布线灵活:引脚间距0.65mm,PCB设计难度低。

4.2 典型应用

凭借宽电压、工业级温度等优势,广泛用于:

  1. 工业控制:PLC模块(存储控制参数)、传感器节点(存储校准值)、电机驱动器(存储转速配置);
  2. 消费电子:智能家居设备(WiFi配置)、可穿戴设备(用户设置)、机顶盒(频道列表);
  3. 通信设备:路由器(MAC地址)、无线模块(配对信息);
  4. 医疗设备:小型家用仪器(患者设置)。

五、产品优势总结

FT24C32A-ETR-T作为辉芒微高性价比器件,核心优势:

  • 宽适配:1.8V~5.5V覆盖全平台,无需电压转换;
  • 高可靠:100年数据保留、100万次写寿命、工业级温度;
  • 高速率:1MHz I2C提升数据交互效率;
  • 小体积:TSSOP-8满足小型化设计。

该器件已通过辉芒微严格可靠性测试(ESD、温度循环),可直接替代AT24C32等进口器件,是嵌入式系统小容量非易失性存储的优选方案。

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
