FT24C512A-TTR-T是辉芒微(FMD)推出的一款串行I2C接口EEPROM,主打高可靠性、宽电压适配和紧凑封装,广泛适用于工业控制、消费电子、物联网等领域的非易失性数据存储需求。
该产品以512Kbit(64KB)存储容量为核心,采用成熟的I2C串行通信接口,兼具「低功耗、高稳定、易集成」三大特点:既满足小型化设计对体积的要求,又能适配多电压平台,同时支持长期数据保留和频繁写操作,是嵌入式系统中参数配置、校准数据、用户设置等非易失存储场景的理想选择。
采用标准I2C串行接口,支持1MHz高速时钟频率,兼容I2C总线的低速(100kHz)、快速(400kHz)模式,可与主流MCU(如STM32、8051、辉芒微自身MCU)、传感器、无线模块等外设无缝对接,无需额外电平转换或接口扩展电路,简化系统设计。
总容量为512Kbit(64KB),支持字节写和页写两种模式(页大小通常为128字节,适配常见EEPROM页结构),单次写周期时间仅5ms/页,大幅提升批量数据写入效率,避免系统等待时间过长。
工作电压覆盖1.7V~5.5V宽范围,可直接适配1.8V低功耗MCU、3.3V主流嵌入式系统及5V传统电路,无需电平转换;工作温度范围为**-40℃+85℃**,满足工业级(-4085℃)和商业级(0~70℃)双场景应用,适应极端环境温度变化。
数据保留时间(TDR)达100年,即使产品长期断电(如工业设备闲置、消费电子待机),存储数据仍能稳定保存;写周期寿命为100万次,可承受频繁数据更新(如传感器校准值定期修改、用户设置动态调整),降低产品后期维护成本。
采用TSSOP-8封装,引脚数8,引脚间距0.65mm,体积仅约3mm×3mm(典型值),相比传统DIP封装体积缩小60%以上,便于嵌入式系统的紧凑型PCB布局,适配智能穿戴、小型传感器节点等小体积产品。
由国内知名半导体厂商辉芒微(FMD)出品,产品经过严格的可靠性测试(包括ESD抗干扰测试、温湿度循环测试、高低温存储测试等),符合RoHS环保标准,质量稳定,已在工业控制、汽车电子辅助应用、消费电子等领域实现批量落地。

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.
