RX8130CE:BB 产品概述

一、产品简介

RX8130CE:BB 是爱普生(EPSON)推出的一款低功耗实时时钟(RTC)芯片,采用 SMD-10P 封装、内置晶振,无引线设计,通过 I2C 总线进行通信。该器件集成备份电源管理与电池充电功能,适合要求长时间时间保持、低待机功耗和可靠唤醒/告警功能的嵌入式与便携设备。

二、主要特性

  • 接口类型:I2C(标准两线接口),便于与主控 MCU/CPU 对接。
  • 晶振类型:内置晶振,系统设计时无需外部晶体或谐振器,节省 PCB 空间并简化布局。
  • 闹钟/告警输出:具备独立告警输出(可用于唤醒或驱动中断处理)。
  • 周期性中断输出:支持可编程周期性中断,适合定时唤醒、心跳监测或周期任务调度。
  • 可编程时钟输出:可输出方波或时钟信号,用于系统同步或外设时钟。
  • 备份电源管理与电池充电:内置备份电源切换与充电管理,自动在主电源失效时切换至电池供电并维持计时。
  • 睡眠/唤醒控制:支持低功耗睡眠模式与外设唤醒,实现能耗优化。

三、电气与环境参数(典型/范围)

  • 工作电压:1.25 V ~ 5.5 V,适应单节锂电池、纽扣电池或多种供电方案。
  • 工作电流:典型 3.5 µA(运行时低功耗领导级别)。
  • 静态电流(Iq):300 nA(待机/备份模式下极低漏电),延长电池寿命。
  • 工作温度范围:-40 ℃ ~ +85 ℃,满足工业级环境要求。
  • 封装:SMD-10P(无引线),小型化、易于表面贴装加工。

四、功能亮点与应用场景

功能亮点:

  • 内置晶振与低静态电流组合,保证长期稳定计时且对备用电源消耗极低。
  • 综合的电源备份与充电管理,简化外部电路设计与电池管理策略。
  • 多种中断与输出选项(闹钟、周期中断、可编程时钟)提高系统灵活性。

典型应用:

  • 可穿戴设备与便携医疗设备:对电池寿命与体积要求高的场合。
  • 工业控制与数据记录器:需要稳定计时、跨断电持续记录的场合。
  • 智能家居与物联网节点:低功耗唤醒、定时任务与事件记录。
  • POS、终端与导航设备:实时时钟与事件报警要求的商业应用。

五、设计与集成建议

  • 电源设计:在主供电与备份电池之间保持清晰的电源路径与去耦,按手册建议放置旁路电容以抑制噪声。
  • I2C 总线:建议使用合适的上拉电阻并注意总线速率与时序,确保与主控兼容。
  • 告警/中断线路:将闹钟输出或周期中断连接到 MCU 中断引脚以降低轮询带来的CPU占用。
  • 热管理与布局:SMD-10P 小封装利于紧凑布局,但在极端温度/高湿环境下应考虑散热与防潮处理。
  • 备份电池选型:根据静态电流 300 nA 与应用中备份时间需求,选取合适容量的钮扣电池或超级电容,并参考芯片充电规格配置充电电路。

六、选用理由与优势

  • 极低功耗与宽电压范围使 RX8130CE:BB 在多种电源方案中都能稳定工作并延长电池寿命。
  • 内置晶振与封装小型化显著降低 BOM 复杂度与占板面积。
  • 完整的备份与充电管理、可编程告警与周期中断,提升系统可靠性与功能灵活性。
  • 工业温度等级与 EPSON 品牌保证了长期稳定性与供应链可靠性。

总结:RX8130CE:BB 是一款面向低功耗、空间受限和需可靠时间保持应用的高集成度 RTC 方案。对于需要长时间备份、简化硬件设计并具备灵活定时/告警能力的产品,RX8130CE:BB 提供了实用且经济的选择。若需详细管脚、寄存器和充电参数,请参考 EPSON 官方数据手册以完成电路与软件设计对接。

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
