PCF8563TS/4,118 产品概述

一、产品简介

PCF8563TS/4,118 是恩智浦(NXP)的一款低功耗实时时钟(RTC)芯片,采用 I²C 双线串口通信,封装为 MSOP-8。芯片集成日历与时钟功能,支持闹钟输出,适合需要长时间电池备份与低静态功耗的便携与嵌入式系统应用。工作电压范围宽(1.0V~5.5V),工作温度覆盖工业级(-40℃~+85℃),便于多种电源与环境条件下使用。

二、主要性能特点

  • 接口类型:兼容 I²C 双线串行总线(标准/快速模式),便于与主控 MCU 集成。
  • 工作电压:1.0V~5.5V,支持单节锂电池或常见系统电源直接供电。
  • 超低静态电流:静态电流 Iq ≈ 0.25 μA(250 nA),适合对待机功耗要求极高的设计。
  • 晶振:内置振荡器/振荡电路(用户可按设计要求配置外部石英),确保长时间稳定计时。
  • 闹钟/定时器输出:具备可编程闹钟和定时器功能,可用于唤醒 MCU 或触发外部事件。
  • 日历功能:提供秒、分、时、日、周、月、年等寄存器,含闰年处理与日历进位逻辑。
  • 工作温度:-40℃~+85℃,满足工业级应用可靠性需求。

三、封装与引脚信息

  • 封装类型:MSOP-8(宽度约 3.00 mm),也常见于 TSSOP-8/8 引脚小型封装,适合空间受限的 PCB 布局。
  • 引脚分布简洁,通常包含电源、地、I²C SDA/SCL、闹钟/中断输出及晶振/时基相关引脚,便于电路连接与布局。

四、电气与环境指标(要点)

  • 供电与功耗:1.0V 至 5.5V 供电范围,静态电流约 0.25 μA;活动模式下电流随操作与 I²C 事务增加,请参考详细数据手册以获知不同工作状态的典型消耗。
  • 温度范围:-40℃ 至 +85℃,适用于工业与消费级混合场景。
  • 时钟精度:受内部振荡器特性与外部晶体(如采用)影响,系统需通过晶振选择与软件校准以满足精度要求。

五、典型应用场景

  • 便携式设备的时间记录与电池备份(手持终端、移动传感器)。
  • 工业控制与数据记录系统,需长期维持时间基准且功耗受限。
  • 家用电器与智能家居产品的定时/闹钟功能。
  • 物联网节点、低功耗传感器网络的唤醒定时与事件记录。

六、设计与使用建议

  • 电源与备份:为保证掉电时仍能计时,建议设计电池或超级电容备份,并在 PCB 布局时靠近电源引脚放置去耦电容。
  • I²C 总线:使用合适阻值的上拉电阻,并在总线上考虑噪声抑制与总线复位方案。
  • 晶振与走线:若采用外部 32.768 kHz 晶体,保持晶体引脚走线短且远离高速信号,遵循厂商推荐布局以提高稳定性与精度。
  • 唤醒策略:利用闹钟/中断输出实现 MCU 低功耗唤醒,注意配置输出电平与接口兼容性。
  • 软件校准:由于温度变化与振荡源差异,建议通过软件周期性校准或补偿以维持长期计时精度。

七、选型提示

在选择 PCF8563TS/4,118 时,重点关注所需的封装形式、系统供电电压范围与静态功耗指标。如需更高精度或额外功能,可参考具有温度补偿或更低跳变噪声的 RTC 产品线。购买与设计前,请以恩智浦最新数据手册为准,核实引脚定义与典型电流曲线。

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
