FT24C32A-ELR-T 产品概述
一、主要特性
- 存储容量：32Kbit（内部组织 4096 × 8）
- 接口类型：标准 I2C（双线串行，双向）
- 工作电压：1.7V ～ 5.5V（低电压兼容）
- 时钟频率：最高 1000 kHz（2.5V–5V 时）；400 kHz（1.7V 时）
- 页写模式：32 字节页写，允许部分页写
- 写周期时间（Tw）：自定时，典型最大 5 ms
- 擦写策略：写前自动擦除
- 封装：SOT-23-5；品牌：FMD（辉芒微）
- 工作温度：-40℃ ～ +85℃
- 寿命与保持：写周期寿命 1,000,000 次；数据保留（TDR）100 年
二、功能与保护
- 内置上电复位（POR），上电瞬态可靠复位设备状态
- 硬件写保护（WP 引脚），支持外部管控写入权限
- 施密特触发输入并带噪声抑制，增强总线抗干扰能力
- 自定时写周期减少主控等待负担，简化软件设计
三、典型应用
- 工业控制与配置存储：参数、校准值保存
- 消费类电子与家电：设备序列号、设置存储
- 物联网与智能终端：低功耗标识信息保存
- 仪表与计量设备：长期数据保持与高可靠写入需求
四、设计注意事项
- 在 SDA/SCL 总线上使用合适的上拉电阻以满足 I2C 时序与噪声要求
- 写操作后等待 Tw 完成或轮询设备应答以确保写入完成；尽量避免跨页写入以提高效率
- WP 引脚根据安全需求连接高电平或低电平实现写保护
- 供电旁路电容（如 0.1 μF）靠近封装以提高电源稳定性与抗干扰能力
五、优势总结
FT24C32A-ELR-T 以其宽电压范围、低功耗、高耐久性及强抗噪性能，适用于对数据可靠性和长期保存有严格要求的系统设计，封装小巧便于空间受限产品使用，是工业与消费类应用中高性价比的串行 EEPROM 解决方案。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
