FT24C02A-KSR-T是辉芒微(FMD) 推出的一款低功耗串行EEPROM,属于FT24C系列存储芯片,核心定位为小容量、高可靠、宽适配的嵌入式存储方案,专为需要永久保存少量关键数据的场景设计(如设备ID、校准参数、状态日志等),是替代传统并行EEPROM的高性价比选择。
辉芒微作为国内MCU及存储芯片领域的主流厂商,其FT24C系列经过多年市场验证,具备稳定的性能表现,广泛覆盖工业、消费电子、物联网等多领域应用。
FT24C02A-KSR-T的参数针对嵌入式场景做了针对性优化,关键指标及应用价值如下:
存储容量:2Kbit(256字节)
精准匹配“非大量但关键”数据存储需求(如8字节设备ID、32字节传感器校准值),避免存储资源浪费,同时满足多数嵌入式系统的小容量数据存储场景。
接口类型:I2C串行接口
采用两线(SDA数据、SCL时钟)通信,仅需4个引脚(含电源、地),大幅节省PCB引脚资源;支持多设备级联(通过A0-A2地址引脚设置8个不同地址),适配系统多存储需求。
时钟频率:1MHz
支持I2C快模式传输,数据读写速度比常规100kHz慢模式快10倍,适合对响应效率有要求的场景(如实时设备状态更新)。
工作电压:1.8V~5.5V宽范围
兼容3.3V(主流嵌入式系统)、5V(传统工业设备)及低功耗1.8V(可穿戴、IoT节点)系统,无需额外电平转换电路,降低系统设计复杂度。
写周期时间:5ms
单次页写入时间仅5ms,比多数同容量EEPROM(通常10ms)更快,减少系统等待时间,提升整体响应速度。
数据保留时间:100年
无电源状态下数据可保持100年不丢失,满足“永久保存”类应用(如设备出厂校准值、唯一ID)。
写周期寿命:100万次
比常规EEPROM(10万次)高10倍,适合频繁写入场景(如计数器、电池电量记录、状态日志),大幅延长产品使用寿命。
工作温度:-40℃~+85℃工业级
适应户外、工业现场等恶劣环境(如低温户外传感器、高温车间PLC模块),可靠性远超商业级(0℃~70℃)产品。
FT24C02A-KSR-T采用SOP-8表面贴装封装,体积小巧(尺寸约5.2mm×6.0mm),适合PCB布局紧凑的产品(如小型传感器模块、可穿戴设备)。
接口引脚功能明确:
其中写保护功能可通过硬件开关或MCU控制,避免系统异常时误写入关键数据,提升数据安全性。
结合参数特性,FT24C02A-KSR-T的典型应用包括:
相比同容量串行EEPROM,FT24C02A-KSR-T具备以下核心优势:
FT24C02A-KSR-T凭借小容量、高可靠、宽适配的特性,成为嵌入式系统中存储关键小数据的优选方案,尤其适合对成本、可靠性有双重要求的应用场景。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
