24CW1280T-I/OT是美国微芯(Microchip)推出的工业级I2C接口EEPROM,专为需要长期数据保留、高可靠性读写且对体积敏感的场景设计。产品以128Kbit(16KB)存储容量为核心,结合宽电压、高速接口与宽温工作能力,成为工业控制、消费电子等领域的经典存储器件。
作为Microchip 24C系列的工业级衍生型号,24CW1280T-I/OT的核心定位是小容量、高可靠非易失性存储:
产品参数围绕“可靠性、易用性、适配性”设计,核心指标如下:
采用SOT-23-5封装(尺寸约2.9mm×1.6mm),体积小巧,适合小型化产品(如智能穿戴、微型传感器)。引脚功能如下:
引脚编号 名称 功能说明 1 WP 写保护:拉高禁止写,拉低允许写 2 SDA I2C数据总线(双向,需外接上拉电阻) 3 SCL I2C时钟总线(主机控制输入) 4 VCC 电源输入(1.6V~5.5V) 5 GND 地注意:SDA/SCL需外接1kΩ~10kΩ上拉电阻至VCC,确保信号完整性。
产品适配以下场景:
核心竞争力体现在“长期可靠”:
24CW1280T-I/OT凭借高可靠性、小体积与宽适配性,成为工业、消费电子领域的常用存储器件,参数设计平衡性能与成本,适合对容量要求不高但可靠性要求严格的应用。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
