AT24C16C-STUM-T 产品概述

一、概述

AT24C16C-STUM-T 是 MICROCHIP(美国微芯)推出的一款容量为 16Kbit(组织为 2K x 8)的串行 I²C EEPROM。该器件支持高达 1MHz 的 I²C 时钟,工作电压范围宽(1.7V 至 5.5V),并采用小型 SOT-23-5 封装,适合对体积、功耗和兼容性有较高要求的嵌入式设计与存储应用。

二、主要规格参数

  • 存储容量:16Kbit(2K x 8)
  • 接口类型:I²C(双线串行总线)
  • 最大时钟频率(fc):1MHz
  • 访问/时序参考值:550ns(器件快速响应能力的参考指标)
  • 工作电压:1.7V ~ 5.5V(兼容 1.8V / 3.3V / 5V 系统)
  • 写周期时间(Tw):典型 5ms(单页/字节写入完成所需时间)
  • 写周期寿命:1,000,000 次
  • 数据保留(TDR):100 年
  • 工作温度范围:-40℃ ~ +85℃
  • 封装:SOT-23-5(紧凑型表面贴装封装)
  • 品牌:MICROCHIP(美国微芯)

三、产品特性与优势

  • 宽电压工作:1.7V~5.5V 的电压范围使器件能在多种电源域下稳定工作,便于系统级电源兼容设计。
  • 快速 I²C 通讯:支持高达 1MHz 的 I²C 时钟,适合对总线速度有要求的系统。
  • 高可靠性:百万次写擦写寿命与 100 年的数据保留,适合长期数据保存和频繁写入的场景。
  • 小尺寸封装:SOT-23-5 封装节省 PCB 面积,适用于空间受限的消费电子、便携设备或工业控制板。
  • 标准化接口:I²C 总线广泛支持,方便与主控 MCU/处理器无缝通信。

四、典型应用场景

  • 系统参数与配置存储:保存设备启动参数、校准系数、序列号等非易失性数据。
  • 生产测试与维护:记录生产编号、固件版本或维护日志等信息。
  • 便携电子与消费类设备:例如可穿戴、移动终端中的小容量配置或用户数据存储。
  • 工业与仪表:在恶劣环境下对可靠性和长期数据保留有要求的记录与配置存储。

五、设计与使用建议

  • 上拉电阻:I²C 总线需在 SDA、SCL 上使用合适阻值的上拉电阻,阻值大小根据总线容量与速度选择(常见 2.2kΩ–10kΩ 范围)。
  • 写操作管理:单次写入受页面边界限制,写操作完成前器件需一定写周期(典型 5ms)。推荐使用 ACK 轮询(或等待写完成时序)来判断写入结束,避免在写入周期内发起后续写操作。
  • 电源与时序:为保证可靠性,遵循器件数据表中的电源上电/下电时序;在电源线并联去耦电容以抑制瞬态。
  • 温度与环境:在高温或恶劣环境下,考虑热管理与封装应力对长期可靠性的影响,并在设计里留有余量。
  • PCB 布局:SOT-23-5 小封装引脚间距紧凑,焊盘与走线应按制造商推荐的封装图处理,确保焊接可靠性及良好散热。

六、封装与采购信息

AT24C16C-STUM-T 采用 SOT-23-5 表面贴装封装,适合自动贴装和回流焊工艺。作为 MICROCHIP 品牌产品,建议通过正规代理或授权经销商采购以确保质量与技术支持,并参考最新数据手册获取完整电气特性、引脚定义与时序图。

七、总结

AT24C16C-STUM-T 是一款面向嵌入式和工业应用的通用 16Kb I²C EEPROM,兼具宽电压支持、快速通讯能力与高可靠性,适用于各种对非易失性小容量存储有稳定可靠要求的设计场景。设计时应遵循 I²C 总线规范与器件写入管理建议,以获得最佳使用体验与长期可靠性。

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
