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。
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。
BM8563EHA的电气参数兼顾低功耗与宽适应性,关键指标如下:
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。
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。
BM8563EHA凭借特性优势,广泛应用于以下场景:
相较于同类产品,BM8563EHA核心优势突出:
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。

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.
