HG24C08M5/TR — 8Kbit I2C EEPROM 产品概述

一、产品简介

HG24C08M5/TR 是华冠(HGSEMI)推出的一款 8Kbit(8192 bit = 1024 Byte)串行 EEPROM,采用小封装 SOT-23-5,支持 I2C 总线并可在高达 1MHz 的时钟速率下工作(I2C Fast-mode Plus)。器件面向对非易失性参数存储、配置与校准数据保存有较高可靠性和体积要求的嵌入式、工业与消费类应用。

二、主要规格

  • 接口类型:I2C,最高时钟频率 fc = 1MHz(Fast-mode Plus)
  • 存储容量:8Kbit(1024 Byte)
  • 工作电压:1.7V ~ 5.5V,宽电压范围便于与多种微控制器配合
  • 工作温度:-40 ℃ ~ +85 ℃(工业级)
  • 写周期时间:Tw = 5 ms(典型,单次写入完成所需时间)
  • 数据保持时间:TDR = 100 年
  • 写周期寿命:1,000,000 次
  • 封装:SOT-23-5

三、功能与特性

  • 噪声抑制功能:增强总线抗干扰能力,提高读写可靠性
  • 硬件写保护:提供物理写保护引脚,防止意外写操作(具体极性与连接方式请参考数据手册)
  • 支持 ACK 轮询以缩短写等待时间,兼容常见 I2C 主控器
  • 小体积封装,利于空间受限的设计布局

四、典型应用场景

  • 系统配置、产品序列号与校准参数存储
  • IoT 终端与传感节点的非易失性参数保存
  • 工业控制器、仪表与测量设备的参数备份
  • 消费电子、家电控制板的固件配置与状态保存

五、设计与使用建议

  • 电源去耦:在 VCC 与 GND 之间放置 0.1µF 陶瓷去耦电容,靠近器件引脚布置
  • I2C 上拉电阻:根据总线长度与工作速率选择典型 2kΩ ~ 10kΩ 的上拉电阻;高频(1MHz)时可适当减小阻值
  • 写入策略:尽量合并写入并减少不必要的写周期以延长使用寿命;利用 ACK 轮询或读回校验确认写完成(Tw ≈ 5 ms)
  • 硬件写保护:根据系统需求配置 WP 引脚,关键数据在不允许修改时应使能写保护
  • 电源与信号顺序:避免在 VCC 未稳定时操作总线,避免浮空 SDA/SCL 引脚影响通信

六、封装与引脚提示

SOT-23-5 小封装便于节省 PCB 面积,适合贴片工艺。WP(写保护)引脚应按数据手册建议连接;SDA、SCL 需通过上拉电阻至 VCC。

七、可靠性与长期维护

HG24C08M5/TR 提供 100 年数据保持和 1,000,000 次写入寿命,适合对长期保存与高写入次数有严格要求的应用场景。为保证长期可靠性,建议在系统设计中采取写均衡、写次数限制与数据校验机制。

总结:HG24C08M5/TR 以其宽电压、工业级温度范围、1MHz 高速 I2C 支持、噪声抑制与硬件写保护等特性,适用于需要小封装、高可靠非易失性存储的多种嵌入式与工业应用。更多详细电气参数与时序建议请参照华冠官方数据手册。

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
