FT24C128A-TNR-T 产品概述

一、概述

FT24C128A-TNR-T 是辉芒微(FMD)推出的一款高可靠性串行 EEPROM,采用标准 I2C 双线接口,容量为 128Kbit(16KB)。器件支持高达 1MHz 的总线时钟速率(Fast-mode Plus),工作电压宽范围 1.8V 至 5.5V,工作温度范围 -40℃ 至 +85℃,并采用超小型 UDFN-8 (2×3mm) 封装,适用于空间受限的嵌入式与便携式设备。凭借长寿命的数据保持特性与高写入耐久性,该器件适合要求长期可靠保存配置信息、校准参数及用户数据的应用场景。

二、主要规格

  • 接口类型:I2C(标准双线接口,支持 1MHz 通讯速率)
  • 存储容量:128 Kbit(16 Kbyte)
  • 时钟频率 (fc):最高 1 MHz
  • 写周期时间 (Tw):典型 5 ms
  • 数据保留 (TDR):100 年
  • 写周期寿命:1,000,000 次
  • 工作电压:1.8 V ~ 5.5 V
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:UDFN-8 (2×3 mm)
  • 其它:内置上电复位(POR)、硬件写保护、噪声抑制功能

三、功能特性

  1. 内置上电复位(POR):保证上电/掉电过程中的内部状态复位,避免电源抖动导致的数据错误。
  2. 硬件写保护:提供外部写保护引脚,可在需要时物理禁止写操作,增强数据安全性。
  3. 噪声抑制:内部有抗干扰处理机制,提升在噪声环境下的读写稳定性,适合工业类应用。
  4. 高耐久与长保持:1,000,000 次写周期与 100 年数据保持,满足对可靠性有高要求的应用。
  5. 宽电源范围:1.8V~5.5V 支持多种系统电压方案,便于与 MCU、传感器等外设直接兼容。

四、封装与引脚(简述)

FT24C128A-TNR-T 采用 UDFN-8 小尺寸封装(2×3mm),适合贴片自动化生产,节省 PCB 空间。器件引脚包含 I2C 时钟(SCL)、数据(SDA)、电源(VCC、GND)、写保护(WP)等标准引脚,便于在常见电路中快速集成。

五、典型应用

  • 消费类电子:智能家电、可穿戴设备、智能遥控器等配置与固件参数保存。
  • 工业控制:设备参数存储、校准数据与故障记录。
  • 智能计量:能耗计、传感器模块中历史数据与校准常数存储。
  • 医疗仪器与仪表:长周期数据保存与设备唯一标识。
  • 物联网与嵌入式系统:系统配置、证书与安全参数存储。

六、设计建议与可靠性

  • 上电/掉电:建议在系统电源线上使用去耦电容,并利用器件内置 POR 以确保稳定上电行为。
  • 写操作管理:写周期约为 5 ms,建议使用 ACK 轮询或等待写完成机制避免在写操作期间发起新的存取。
  • 写保护使用:对于关键配置或出厂参数,可将 WP 引脚固定到写保护状态,防止误写。
  • 抗干扰:在高噪声环境中推荐加装滤波与合理的 PCB 布线,配合器件噪声抑制特性可获得更佳稳定性。
  • 可靠性验证:器件提供 100 年数据保持和 1,000,000 次写耐久,适合要求长期可靠性的产品设计。

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
