BM8563EMA 实时时钟(RTC)产品概述

BM8563EMA是捷茂微(GATEMODE) 推出的一款低功耗实时时钟器件,采用超小尺寸MSOP-8L_3X3MM封装,针对便携电子、工业控制、消费电子等对功耗、空间和可靠性要求较高的场景设计,核心特点是宽电压范围、极低静态电流和灵活的定时功能。

一、产品核心定位与优势

BM8563EMA聚焦“低功耗+高适配性+实用功能”三大核心,解决传统RTC在供电兼容性、电池寿命和定时灵活性上的痛点:

  • 宽电压适配:1.2V~5.5V工作电压覆盖纽扣电池(如CR2032)、锂电池、直流稳压电源等多种供电方式,无需额外电平转换;
  • 超省电设计:静态电流(Iq)仅0.5μA,正常计时电流500nA,纽扣电池可支持数年连续工作,降低设备维护成本;
  • 灵活定时功能:内置闹钟输出引脚,支持定时唤醒或中断触发,适配MCU低功耗模式(如STOP/IDLE模式);
  • 工业级可靠性:-40℃~+85℃宽温区工作,满足户外、车载、工业现场等极端环境需求。

二、关键技术参数详解

BM8563EMA的参数设计围绕“低功耗”和“兼容性”展开,核心参数如下:

1. 通信与接口

  • 采用I2C串行接口,支持标准I2C速率(100kHz),通信协议简洁,可与主流MCU(如STM32、ESP32等)直接对接,无需复杂驱动;
  • 地址固定(通常为0x51/0x52),无地址冲突风险,支持单设备或多设备组网。

2. 供电特性

参数 数值范围 说明 工作电压(VDD) 1.2V~5.5V 覆盖纽扣电池、锂电池等 静态电流(Iq) 0.5μA(典型值) 待机模式下极低功耗 工作电流 500nA(典型值) 正常计时时的电流消耗 耗散功率(Pd) 300mW(最大值) 封装允许的最大功耗,安全余量充足

3. 计时与功能

  • 外置晶振:需配合32.768kHz石英晶振(OSC1/OSC2引脚),用户可根据精度需求选择不同品质晶振(如温补晶振提升温漂稳定性);
  • 闹钟输出:INT/ALARM引脚支持单次/重复闹钟,输出类型可选开漏/推挽,适配不同MCU IO电平;
  • 计时精度:常规32.768kHz晶振日漂移约±20ppm(每日误差±1.7s),满足大多数应用需求。

4. 环境适应性

  • 工作温度:-40℃~+85℃(工业级温区);
  • 存储温度:-55℃~+125℃(工业级存储要求);
  • 抗干扰性:内置ESD保护(符合IEC 61000-4-2标准),适应复杂电磁环境。

三、封装与引脚配置

BM8563EMA采用MSOP-8L_3X3MM封装,尺寸仅3mm×3mm,引脚间距0.65mm,适合高密度PCB设计(如智能穿戴、小型传感器节点)。常见引脚功能如下:

引脚编号 引脚名称 功能说明 1 VDD 电源输入(1.2V~5.5V) 2 SDA I2C数据引脚(需上拉) 3 SCL I2C时钟引脚(需上拉) 4 INT/ALARM 闹钟输出/中断引脚 5 OSC1 晶振输入引脚 6 OSC2 晶振输出引脚 7 GND 地 8 NC 空脚(无连接)

四、典型应用场景

BM8563EMA的低功耗、宽温区和灵活功能使其适配多类场景:

1. 便携电子设备

  • 智能手环/手表:纽扣电池供电,定时唤醒显示时间,延长续航;
  • 无线耳机/蓝牙音箱:定时自动关机,节省电量。

2. 工业控制与物联网

  • 传感器节点:远程环境监测(温湿度、水位),定时上报数据,降低功耗;
  • PLC模块:工业现场计时与定时控制,适应极端温度。

3. 消费电子与智能家居

  • 电子秤/计时器:精准计时,支持定时清零;
  • 智能开关/插座:定时开关控制,适配家庭用电场景。

4. 车载电子

  • 车载导航/行车记录仪:宽温区适应车内温度变化,定时唤醒记录数据。

五、应用设计注意事项

为确保稳定工作,需注意以下要点:

  1. 晶振匹配:OSC1/OSC2并联12pF/16pF负载电容(与晶振规格匹配),避免停振或误差;
  2. 电源滤波:VDD串联100nF陶瓷电容到GND,减少噪声干扰;
  3. I2C上拉:SDA/SCL接4.7kΩ~10kΩ上拉电阻到VDD,确保通信稳定;
  4. 电平匹配:若MCU为5V电平,INT/ALARM需加三极管电平转换。

BM8563EMA以高性价比、低功耗和宽适配性,成为中小尺寸设备中RTC方案的优选,尤其适合对电池寿命和空间要求严格的应用场景。

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.
