BM8563EHA 实时时钟模块产品概述

BM8563EHA是捷茂微(GATEMODE)推出的一款低功耗I2C接口实时时钟(RTC)芯片,专为需要精准计时、低功耗运行及宽环境适应性的电子设备设计。该芯片集成核心计时功能与灵活外设控制,可满足消费电子、工业控制、便携设备等多领域的计时需求。

一、产品定位与核心功能

作为通用型RTC芯片,BM8563EHA围绕精准时间管理展开核心功能:支持秒、分、时、日、月、年全维度计时,内置自动闰年补偿(兼容2000-2099年),无需手动调整时间偏移;同时具备可编程闹钟功能,可通过硬件引脚输出唤醒信号,帮助系统在低功耗模式下实现定时唤醒,有效降低整体功耗。

二、核心电气参数特性

BM8563EHA的电气参数兼顾低功耗与宽适应性,关键指标如下:

  • 工作电压范围:1.2V~5.5V,覆盖常见MCU(3.3V/5V系统)及纽扣电池(如CR2032)供电范围,无需额外电平转换;
  • 静态电流:典型值仅0.5uA(500nA),电池供电场景下可实现数年续航,极大延长设备待机时间;
  • 工作温度范围:-40℃~+85℃,符合工业级标准,稳定运行于户外、车载等 harsh 环境;
  • 晶振配置:支持外置32.768kHz晶振,用户可根据精度需求选择不同品质晶振,灵活平衡成本与性能;
  • 闹钟输出:具备独立闹钟输出引脚,支持单次/重复闹钟设置,输出电平可配置(高/低有效)。

三、接口与封装设计

3.1 通信接口

采用I2C串行接口,仅需SDA(数据线)、SCL(时钟线)两根引脚即可与MCU通信,支持标准模式(100kHz)与快速模式(400kHz),兼顾兼容性与传输效率;内置I2C地址选择功能,可通过硬件引脚配置多设备级联,满足复杂系统多RTC需求。

3.2 封装形式

选用TSSOP-8封装,体积小巧(约3.0mm×4.4mm),引脚间距0.65mm,适合小型化设备PCB布局,同时便于手工焊接与自动化贴装,降低生产难度。

四、典型应用场景

BM8563EHA凭借特性优势,广泛应用于以下场景:

  1. 便携电子设备:智能手环、手表、运动相机等,低功耗延长纽扣电池续航;
  2. 医疗健康设备:血糖仪、血压计、可穿戴医疗设备,精准计时记录生理数据;
  3. 工业控制与物联网节点:PLC模块、环境传感器节点、智能农业设备,宽温范围适应户外/车间环境;
  4. 智能家居与安防:智能插座、监控摄像头、门禁系统,闹钟功能实现定时唤醒与事件触发;
  5. 电池供电类产品:电子日历、闹钟、便携打印机,无需频繁更换电池。

五、产品关键优势

相较于同类产品,BM8563EHA核心优势突出:

  • 超低静态功耗:0.5uA静态电流远低于多数竞品,电池续航提升30%以上;
  • 宽电压兼容:1.2V~5.5V覆盖全场景供电,适配不同MCU与电池类型;
  • 灵活晶振配置:外置晶振设计让用户按需选择,平衡成本与精度;
  • 工业级可靠性:-40℃~+85℃温度范围,确保极端环境稳定计时;
  • 小封装易集成:TSSOP-8封装体积小,适合高密度PCB设计,降低系统空间占用。

该芯片以高性价比、高可靠性成为各类计时需求设备的优选方案,可快速适配不同系统设计。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
