FT24C64A-ESR-B 产品概述

一、产品简介

FT24C64A-ESR-B 是辉芒微(FMD)推出的一款低功耗、宽电压、工业级 I2C 串行 EEPROM,容量为 64Kbit(8KByte)。器件兼容 I2C 双线协议,支持标准及快速传输速率,通信时钟频率覆盖 100kHz(标准模式)、400kHz(快速模式)及最高 1MHz(快速模式+),便于与各类微控制器和系统总线集成。器件采用 SOP-8 封装,工作电压范围宽(1.8V ~ 5.5V),工作温度覆盖 -40℃ ~ +85℃,适合消费类与工业级应用。

二、主要特点

  • 存储容量:64Kbit(8KByte),用于参数、配置表、标识码等非易失性数据存储。
  • 接口类型:I2C 双线接口,兼容 7 位从地址访问,支持高达 1MHz 的时钟频率。
  • 工作电压:1.8V ~ 5.5V,单电源宽电压设计,便于与不同逻辑电平系统直接连接。
  • 写入性能:典型写周期时间 Tw = 5ms(每字节或页写入完成所需时间)。
  • 数据保持:TDR(数据保留)≥ 100 年,适合长期数据保存需求。
  • 擦写寿命:写周期寿命 ≥ 1,000,000 次,耐用可靠。
  • 功能特性:内置上电复位(POR),硬件写保护(WP 引脚),噪声抑制功能,提高系统稳定性与可靠性。
  • 封装:SOP-8,适配常用 DIP/SMD PCB 布局与自动贴装生产线。
  • 工作温度:-40℃ ~ +85℃,满足工业环境使用要求。

三、功能与优势解析

  • 宽电压兼容:1.8V~5.5V 设计使 FT24C64A-ESR-B 能在低功耗移动设备与传统 5V 工业设备间无缝使用,减少电平转换电路,简化系统设计。
  • 抗干扰与可靠性:内置噪声抑制功能与上电复位(POR)降低电源波动、干扰对存储读写造成的数据错误,提高系统可靠性。
  • 硬件写保护:外部 WP 引脚可在需要时物理锁定写入功能,防止意外或恶意写入,用于安全关键配置信息保护。
  • 长期数据保持与高耐久性:100 年数据保存与百万次写周期寿命,特别适合需要长期保存配置/校准数据或频繁写入的场景。

四、典型应用场景

  • 工业控制:设备参数存储、故障日志、校准系数、固件版本标识等。
  • 智能电表与仪表:计量参数、历史配置、设备序列号与校准数据储存。
  • 汽车电子(非关键安全回路):车载信息管理、配置数据、维护记录(需遵循车规适配与认证)。
  • 消费类电子:可穿戴设备、遥控器、智能家居模块的配置信息与用户偏好保存。
  • 物联网与通信设备:节点配置、网络凭证缓存、设备识别信息等。

五、使用建议

  • I2C 拉升电阻:为保证通信可靠性,SDA/SCL 线路需配合适的上拉电阻,阻值依系统电源与总线负载选择(常用 2.2k~10kΩ)。
  • 写入管理:遵循写周期时间(Tw ≈ 5ms),连续写操作间应保证器件完成内部写入循环,或者通过器件的忙检测机制(ACK/NACK)来判断写入完成。
  • 写保护策略:在需要防止误写的场合,将 WP 引脚拉至写保护有效电平;在写入时解除保护。
  • 电源与接地:良好去耦和稳压设计有助于 POR 和噪声抑制功能发挥效能,减少通信错误。
  • 封装与散热:SOP-8 封装适合自动贴装工艺,注意 PCB 热回流工艺及焊盘设计以保证可靠焊接。

六、封装信息与选型提示

FT24C64A-ESR-B 提供 SOP-8 表面贴装封装,适合批量化生产的 PCB 布局。选型时请确认系统工作电压、环境温度范围与 I2C 总线速率需求;若需更高温或车规级要求,请咨询供应商或查看相应高可靠性产品系列。

如需器件引脚定义、电气特性曲线、时序图和参考电路,请索取 FT24C64A-ESR-B 详细规格书(Datasheet)以获得完整的设计资料与典型应用示例。

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
