FT24C128A-TSR-T 产品概述

一、产品简介

FT24C128A-TSR-T 是一款由 FMD(辉芒微) 推出的 131,072 位串行电可擦可编程只读存储器(EEPROM),采用先进 CMOS 工艺制造,适用于低电压、低功耗系统。器件通过标准 2 线双向串行接口(I2C)与主控通信,容量为 128Kbit(16KB),在工业级温度范围内提供长期、可靠的数据存储解决方案。

二、主要参数

  • 存储容量:128Kbit(131,072 位,16KB)
  • 接口类型:I2C 双线串行接口
  • 最大时钟频率 fc:1MHz
  • 写周期时间 Tw:典型 5ms(自定时写周期)
  • 数据保持时间 TDR:100 年
  • 写周期寿命:1,000,000 次
  • 工作电压:1.7V ~ 5.5V
  • 工作温度:-40°C ~ +85°C
  • 封装形式:SOP-8
  • 核心功能:上电复位(POR)、硬件写保护、噪声抑制、部分页面写入支持

三、功能特点与优势

  • 宽电压范围(1.7V–5.5V):适配单节锂电池、微控制器以及多种电源方案,便于在低功耗或电源波动环境中可靠工作。
  • 高可靠性:数据保留 100 年、写入寿命高达 100 万次,适合要求长期保持数据完整性的应用。
  • 自定时写入与部分页面写入:内部实现自定时写周期,避免外部时序复杂度;支持部分页面写入以提高写操作效率并降低总线占用。
  • 硬件写保护与 POR:提供外部硬件写保护引脚以防止误写,内置上电复位确保上电/掉电过程中的数据和状态安全。
  • 噪声抑制:内置噪声抑制功能增强在电磁干扰或长线应用环境下的数据稳定性。

四、典型应用场景

  • 工业控制与数据记录:参数配置、校准数据、日志存储。
  • 消费电子与便携设备:配置表、固件标识、用户设定保存。
  • 智能家居与物联网终端:身份认证参数、长期配置信息存储。
  • 医疗与仪表设备:长期可靠数据保持与频繁读写场合。

五、设计与使用注意事项

  • 写入管理:每次写操作完成后需等待自定时写周期结束(典型 Tw = 5ms),或通过器件的就绪轮询机制确认写入完成,避免在写入期间发起新写命令。
  • 电源与去耦:为保证 POR 与稳定工作,建议在 VCC 端加适当旁路电容,设计上考虑上电/下电的斜率,避免不稳定电平造成误操作。
  • 硬件写保护:关键数据建议配合 WP 引脚实现硬件级写保护,必要时结合软件层校验提升数据安全。
  • 抗噪设计:在噪声较大的环境中,使用差分传输或增加滤波与串联阻抗等硬件措施以配合器件的噪声抑制功能。
  • 总线速率:器件支持最高 1MHz 时钟频率,设计时按 I2C 总线拓扑和负载能力合理选择上拉电阻与时序参数。

六、封装与选型建议

FT24C128A-TSR-T 提供 SOP-8 封装,便于在常规 PCB 工艺中插装与自动贴装。选型时关注工作电压区间与工作温度是否满足整机设计要求,以及是否需要硬件写保护与长寿命写循环的特性。如需更高温度等级或不同封装,可联系供应商确认产品线与定制选项。

总结:FT24C128A-TSR-T 以其宽电压输入、长数据保持、百万次写耐久、自带 POR 与硬件写保护等特性,适合各类需要稳定、长期存储和频繁配置更新的嵌入式与工业应用场合。若需原理接线图、应用电路或时序示例,可进一步提供系统拓扑以便给出针对性建议。

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
