AT24C04C-XHM-T 产品概述
一、简介
AT24C04C-XHM-T 是 Microchip（美国微芯）推出的一款 I²C 接口的串行 EEPROM，容量为 4Kbit（512 x 8）。器件支持最高 1MHz 的 I²C 时钟频率（Fast-mode Plus），具有快速响应（时序响应 550ns）和低功耗特性，适用于对非易失性配置、序列号、校准数据及小容量参数存储的应用场景。
二、主要特性
- 存储容量：4Kbit（512 × 8）
- 接口类型：I²C，最高支持 1MHz（Fast-mode Plus）
- 工作电压：1.7V 至 5.5V，支持典型单电源系统
- 工作温度：-40℃ 至 +85℃（工业级）
- 写周期时间（Tw）：约 5ms（典型）
- 数据保持（TDR）：100 年
- 写周期寿命：1,000,000 次
- 硬件写保护：提供写保护引脚，可在系统级防止误写
- 抗噪声设计：内置噪声抑制功能，提高总线鲁棒性
- 上电复位：内置电源上电复位（POR）以保证上电时数据一致性
- 封装：8 引脚 TSSOP（便于 PCB 布局与密度控制）
三、关键电气与时序参数
AT24C04C-XHM-T 在 1.7V–5.5V 电压范围内稳定工作，内部包含电源监测与上电复位电路，避免异常上电造成的数据损坏。典型写周期约 5ms，器件保证长期数据保存（100 年）与高写入寿命（1,000,000 次），满足苛刻应用的可靠性需求。器件对总线噪声有抑制措施，时序响应可达到 550ns，适合需要快速读回的小容量数据应用。
四、应用场景
- 工业控制：配置参数、设备标识和校准常数存储
- 消费电子：产品序列号、生产信息与设置备份
- 医疗与仪表：长期保存校准系数与历史配置
- 通信与嵌入式系统：固件外设小量参数与用户设置
五、使用建议与注意事项
- 在系统设计中利用写保护引脚（WP）实现对关键数据的硬件保护。
- 避免在写周期（约 5ms）期间断电或发起新的写操作，以免造成数据异常。
- 对总线布局应考虑噪声抑制和上拉电阻选型，结合器件的噪声抑制能力可提升通信可靠性。
- 若需在高频扰动环境中使用，建议在电源和 I²C 总线上加入适当滤波与旁路电容。
六、可靠性与封装
AT24C04C-XHM-T 提供 8-TSSOP 封装，便于自动化贴装与散热。器件在工业温度范围内有长期数据保持和高写入次数保证，适合需要长期稳定存储的产品方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
