11AA02E48T-I/TT 是 MICROCHIP(美国微芯)推出的一款高可靠性、低功耗的 2Kbit 串行 EEPROM,采用单总线(单线)通信接口,工作电压范围宽(1.8V 至 5.5V),工作温度范围为 -40℃ 到 +85℃,封装为 SOT-23-3,适合空间受限且对数据长期保存有高要求的嵌入式系统与消费电子设备。
该器件提供高达 100 万次的写循环寿命,配合 200 年的数据保持能力,适合用于需要长期可靠保存关键配置或身份信息的应用。系统设计时应注意减少不必要的写入(例如采用缓存、批量写入或写入次数计数与轮换策略),以最大化整体寿命。
SOT-23-3 小封装便于空间受限设计,但需注意焊接工艺与热回流曲线以保证焊接可靠性。选型时请以 MICROCHIP 官方数据手册为准,确认引脚排列、总线时序、通信协议细节与寄存器/命令集,以便与系统 MCU 或主控正确对接。

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.
