PCF8563MDTR是芯伯乐(XBLW)针对低功耗、宽温适应性场景推出的I2C接口实时时钟(RTC)芯片,继承经典PCF8563架构的稳定性,同时优化了静态功耗与电压兼容性。其核心价值在于:用超小封装实现工业级时间管理,适配电池供电、户外部署等严苛场景,无需复杂外围电路即可满足定时、时钟同步需求。
采用标准I2C接口,支持100kHz(标准模式)和400kHz(快速模式),与STM32、ATmega等主流MCU完全兼容,无需电平转换。默认I2C地址为0xA0(写)/0xA1(读),支持多芯片级联(部分封装可通过电阻扩展地址)。
工作温度范围**-40℃~+70℃**,符合工业级温区标准,可适应户外低温、室内高温或温差变化(如农业传感器、智能电表),无需额外散热/保温。
集成可编程闹钟输出,支持秒、分、时、日、星期多维度触发,输出电平可配置为中断(INT)或电平变化,便于MCU实时响应定时事件(如智能插座开关、医疗设备提醒)。
PCF8563MDTR兼容NXP PCF8563TS等主流产品,在静态电流更低(0.25μA vs 0.6μA) 方面具备优势,适合功耗敏感场景;若需-40℃~85℃温区,可选择芯伯乐同系列高温版本。
该芯片凭借高性价比与稳定性能,已成为便携设备、工业控制领域的主流RTC选择。

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.
