PCF8563MM/TR 产品概述

一、产品简介

PCF8563MM/TR 是一款低功耗的实时时钟(RTC)器件,适用于需要长期计时并在断电或低功耗状态下保持时间信息的嵌入式系统。器件集成了时钟/日历功能并提供闹钟输出,内部晶振已集成,便于在各种工作电压和环境温度下稳定运行。

二、主要功能与特性

  • 支持标准的实时时钟/日历功能(秒、分、时、日、月、年等基本时间信息的维护),可用于定时唤醒与事件触发。
  • 提供闹钟输出,便于与主控进行外部中断或唤醒联动。
  • 内置晶振,无需外部 32.768 kHz 晶体,提高系统集成度和可靠性。
  • I2C 串行接口,通信简单,兼容大多数单片机和处理器的 I2C 主机。
  • 适应宽电压范围 1.8V ~ 5.5V,便于与不同电源域系统配合使用。
  • 宽温度工作范围:-40℃ ~ +85℃,满足工业级应用需求。

三、关键电气参数

  • 工作电流:约 800 µA(典型工作态电流,视工作模式与频率而异)。
  • 静态电流(Iq):约 0.25 µA(低功耗待机态,便于电池供电的长期运行)。
    这些参数表明器件在正常工作与待机时均具有较好的功耗控制,适合电池供电的产品设计。

四、封装与接口注意事项

  • 封装形式:MSOP-8,适合中小型 PCB 布局与空间受限的应用。
  • 接口类型:I2C(SDA/SCL),在 PCB 设计时需配置合适的上拉电阻并留意总线速率与拉电容,以保证通信稳定。
  • 外围建议:建议在电源引脚处加入旁路电容以抑制电源噪声;若系统需要电池后备,请在系统设计中考虑断电切换与电源隔离方案。

五、典型应用场景

  • 便携式仪器与电池供电设备的时间记录与定时唤醒;
  • 工业控制、数据采集设备的时间戳与定期采样触发;
  • 计量、家电与安防设备的定时控制与事件报警;
  • 需要宽电压兼容与工业温度等级的嵌入式系统。

六、设计与选型建议

  • 若追求更高精度,需评估外部温漂与工况对内部晶振的影响;在对时间精度要求严格的设计中,可考虑增加软件校准或外部温度补偿机制。
  • 使用 I2C 总线时,选择合适的上拉电阻值(常见在 2.2k–10k 范围)并控制总线负载以保证信号完整性。
  • 在电池后备与系统主电源切换方案中,注意避免数据丢失与时钟寄存器重置,设计时应保留稳定的后备电源路径。
  • 关注封装的热散与布局,确保器件工作温度保持在推荐范围内以保证长期可靠性。

总之,PCF8563MM/TR 以其低功耗、内置晶振、宽电压与宽温度特性,适合各种需长期计时与低功耗唤醒的嵌入式应用。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
