AT21CS11-STU10-T 产品概述

一、产品简介

AT21CS11-STU10-T 是 MICROCHIP(美国微芯)推出的一款工业级串行 EEPROM,存储容量为 1Kbit,工作温度范围覆盖 -40℃ ~ +85℃,适用于对数据长期保存和高耐久写入有要求的嵌入式系统与消费电子产品。器件采用 SOT-23-3 小封装,体积小,便于空间受限的电路板布局与自动化贴装。

二、主要规格

  • 存储容量:1 Kbit(1024 bit)
  • 接口类型:单总线(文档描述兼顾常见串行总线应用)
  • 工作电压:2.7 V ~ 4.5 V
  • 工作温度:-40 ℃ ~ +85 ℃
  • 写周期时间(Tw):典型 5 ms
  • 数据保留(TDR):100 年
  • 写周期寿命:1,000,000 次
  • 封装:SOT-23-3

三、功能特性

  • 硬件写保护功能:通过外部引脚或器件内部保护机制阻止非授权写操作,提高数据安全性。
  • 页写保护功能:支持对存储页级别的写入限制,便于对关键数据区域进行保护与管理。
  • 快速写周期与长寿命:5 ms 的写周期与百万次写入寿命,适应频繁写入场景,同时保证长期可靠性。
  • 宽电压与工业级温度:2.7 V4.5 V 的供电范围与 -40 ℃+85 ℃ 工作温度,适合电源与环境条件波动较大的应用。

四、典型应用场景

  • 配置参数与校准数据存储:用于记录出厂校准、设备配置和运行参数。
  • 标识与序列号保存:在生产或维修流程中保存设备序列号、出厂信息等不可丢失的数据。
  • 电源断电保持关键数据:用于保存断电前重要状态或统计信息,配合写保护提高数据完整性。
  • 工业控制与消费电子:适用于仪表、通信模块、智能家电、可穿戴设备等需要小容量非易失存储的场合。

五、封装与可靠性

AT21CS11-STU10-T 提供 SOT-23-3 小封装,便于表面贴装并节省 PCB 空间。器件针对长期保存与工业应用设计,100 年的数据保留能力和百万次写入寿命,满足长期维护成本低、可靠性高的需求。工作环境范围覆盖典型工业温度等级,适合恶劣环境下长期运行。

六、选型建议

  • 如需更大容量或多通道总线兼容,请在产品家族中对比更高容量型号或不同接口类型的器件。
  • 关注系统电源与器件工作电压匹配(2.7 V~4.5 V)以保证稳定通信与写入性能。
  • 在安全关键场合,建议结合外部电路实现复合写保护(硬件锁定 + 软件校验)以提高数据可靠性。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
