24LC00T-I/OT 产品概述

一、产品简介

Microchip 24LC00T-I/OT 是一款低功耗、低容量的串行 EEPROM,采用标准 I2C 接口(100 kHz 标准模式),存储容量为 128 bit(16 字节),工作电压范围宽(2.5 V 至 5.5 V),工作温度为 -40 ℃ 至 +85 ℃,封装为 SOT-23-5。该器件适用于存储少量配置信息、序列号、校准常数和设备标识等对容量要求极小但对可靠性要求高的场景。

二、主要参数与特性

  • 接口类型:I2C(兼容 100 kHz 标准模式)
  • 存储容量:128 bit(16 字节)
  • 工作电压:2.5 V ~ 5.5 V(单电源)
  • 工作温度:-40 ℃ ~ +85 ℃(工业级)
  • 写周期时间(Tw,典型):4 ms(写入完成所需时间)
  • 数据保持时间(TDR):200 年(典型)
  • 擦/写寿命:1,000,000 次擦写周期(典型)
  • 封装:SOT-23-5,适合空间受限的 PCB 布局

三、引脚与封装说明

SOT-23-5 五引脚封装,典型功能包括 VCC、VSS(GND)、SDA(双向数据)、SCL(时钟)及一个可配置引脚(视具体版本可能为地址选择或写保护)。在设计时请参考厂商数据手册确认该引脚的具体定义与连接方式。

四、典型应用场景

  • 设备出厂序列号和产品 ID 存储
  • 校准常数、生产追溯信息、软件参数保存
  • 小容量配置参数及用户偏好设定
  • 系统引导时的微小非易失性数据存储

五、设计与使用建议

  • 电源去耦:器件 VCC 端建议并联 0.1 μF 陶瓷电容,靠近封装放置,以抑制电源噪声。
  • I2C 拉电阻:推荐在 SDA、SCL 线上使用 2.2 kΩ~10 kΩ 的上拉电阻,具体阻值依据总线电容和通信速率调整。标准模式(100 kHz)下常见取值为 4.7 kΩ。
  • 总线负载:遵循 I2C 总线最大电容(典型 400 pF)限制,长线或多节点布局时注意分段或增加缓冲。
  • 写入策略:由于写周期(4 ms)较长,避免在写操作期间重复发起写命令;可通过轮询或等待写完成(ACK/NACK 或待机时序)来确认写入完成。
  • 写保护:如果器件支持 WP 引脚,关键数据写入时可通过硬件写保护提升可靠性与安全性。
  • 安全性:128 bit 容量有限,若用于存储密钥或敏感信息,应结合系统加密/安全存储方案,避免明文保存重要凭据。

六、可靠性与供货信息

24LC00T-I/OT 适合工业温度等级应用,数据保持期长、擦写寿命高,适合需长期可靠保存少量非易失性数据的产品。零件号后缀 -I/OT 通常表示工业级温度范围(-40 ℃ 至 +85 ℃)及工业封装供货形式(卷带包装),具体请以 Microchip 官方数据表和采购信息为准。

七、总结

作为一款小容量、低功耗且工作电压范围宽的 I2C EEPROM,24LC00T-I/OT 在需要极少量非易失性存储且对可靠性、寿命有较高要求的应用中具有优势。合理的 PCB 布局、去耦和总线设计能确保稳定通信与长期数据保持。有关引脚定义、时序图和典型电路请参照 Microchip 官方数据手册以获得完整设计细节。

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.
