DS1302ZN(华冠 HGSEMI 代号)是一款面向低功耗实时时钟(RTC)应用的时钟芯片,适合需要长期保持时间信息且断电后仍需维持计时的嵌入式系统。器件采用外置晶振工作、三线串行通信,封装为传统的 DIP-8,便于在面包板及插座式电路中快速调试与替换。
DS1302ZN 在 DIP-8 封装下便于测试与替换,采购时请确认供应商为 HGSEMI(华冠)或有可靠的替代品与技术支持;批量设计中注意查看器件的温度等级与质量认证,结合实际功耗与备用电源方案做最终确认。
总结:DS1302ZN 以其超低待机电流、宽电压范围、简单的三线接口和经典的 DIP-8 封装,适合各种对功耗和可靠性有严格要求的时钟应用。设计时关注晶振布局、电源去耦与接口时序,可获得稳定可靠的计时性能。

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.
