AT24C08M5/TR 产品概述

一、产品简介

AT24C08M5/TR 是华冠(HGSEMI)推出的一款 8Kbit 串行 I2C EEPROM,采用紧凑的 SOT23-5 封装,面向配置存储、校准数据保存、序列号记录及轻量级日志等应用场景。器件支持 I2C 总线接口,最高时钟频率可达 1MHz,工作电压范围宽(1.7V ~ 5.5V),工作温度 -40℃ ~ +85℃,适合多种嵌入式与工业级产品设计。

二、主要电气与时序特性

  • 存储容量:8Kbit(1024 字节),适用于小型非易失性数据保存。
  • 接口类型:I2C(多器件总线共享),兼容常见 I2C 主控。最高时钟频率 fc = 1MHz。
  • 写周期时间:Tw = 5ms(典型写入完成时间);建议写入后等待或采用 ACK 轮询方式确认写操作完成。
  • 数据保持:TDR = 100 年(典型数据保持期),适用于长寿命产品需求。
  • 写入寿命:写周期寿命达 1,000,000 次,可靠性高,适合频繁写入的配置存储场景。
  • 电源范围:1.7V ~ 5.5V,便于多电压系统直接集成。

三、功能亮点

  • 噪声抑制功能:内置噪声抑制电路,提高在电磁干扰或总线噪声环境下的数据稳定性。
  • 硬件写保护:提供硬件 WP(写保护)引脚,可用于快速实现对整片或特定地址段的写保护策略(具体极性与实现方式请参阅产品手册)。
  • 小尺寸封装:SOT23-5 小封装占板面积小,便于空间受限的移动与消费类设备设计。

四、封装与引脚概述

  • 封装:SOT23-5,适合紧凑型 PCB 布局。
  • 常见引脚功能:VCC、GND、SDA、SCL、WP(写保护)。(具体引脚排列和功能请以官方封装图为准)

五、设计与使用建议

  • 电源与去耦:建议在 VCC 与 GND 之间放置 0.1µF 陶瓷去耦电容,靠近器件引脚布置以降低电源噪声影响。
  • I2C 拉电阻:根据总线长度与速率选择合适的上拉电阻(常见值 1kΩ ~ 10kΩ,典型 4.7kΩ),速率越高或总线容量越大需采用更小阻值。
  • 写入管理:写操作需满足 Tw(5ms),可采用 ACK 轮询以缩短等待时间并提高总线利用率。避免在电源不稳或重置过程中写入,以防止数据损坏。
  • 写保护策略:在需要防止意外写入的场合使用 WP 引脚实现硬件级保护;在产品初始烧录与调试阶段合理控制 WP 状态。
  • 温度与可靠性:器件工作温度 -40℃ ~ +85℃,适用于大多数工业与消费场景。长期可靠性受限于工作环境与写入模式,请依据实际应用评估写入频率对寿命的影响。

六、典型应用场景

  • 嵌入式系统的配置与校准数据保存
  • IoT 终端设备的固件版本号与设备序列号存储
  • 工业控制器的参数与状态记录
  • 消费电子产品的用户设置与偏好保存
  • 需要长期保存少量关键数据的应用

总结:AT24C08M5/TR 以其 8Kbit 的容量、1.7V~5.5V 的宽电源范围、1MHz 的 I2C 支持、长数据保持与高写入寿命,结合噪声抑制与硬件写保护特性,适合空间受限且对可靠性有较高要求的存储需求。在实际设计中注意去耦、总线上拉、电平兼容及写入管理等细节,可获得稳定、长期可靠的存储表现。若需进一步电气参数、引脚定义或时序图,请参阅厂家完整数据手册。

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
