MCP79410T-I/SN是美国微芯(Microchip)推出的工业级低功耗实时时钟芯片,专注于嵌入式系统的精准时间管理与数据存储。型号后缀中:
该芯片的参数兼顾低功耗、宽适配与可靠性,核心指标如下:
支持年(2000-2099)、月、日、星期、时、分、秒全维度记录,自动闰年调整(含世纪切换),24小时/12小时制可配置,满足不同系统的时间显示需求。
具备单次/每日重复闹钟功能,通过专用INT引脚输出低电平中断,触发MCU从待机模式唤醒,无需轮询RTC,大幅降低系统整体功耗。
内置备用电池切换电路(VBAT引脚):主电源(VDD)掉电时,自动切换至备用电池,保持时间和SRAM数据不丢失;1Kb EEPROM为非易失存储,无需备用电池即可长期保存系统配置、日志等数据。
支持软件校准寄存器(I2C写入校准值),补偿晶振误差;内置电源监控电路,防止电压异常导致的时间丢失。
MCP79410T-I/SN的低功耗、宽温特性适配多类场景:
该芯片是嵌入式系统时间管理的高性价比选择,尤其适合对功耗、温度适应性有要求的应用场景。

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.
