RX8900CE:UB3是爱普生(EPSON)推出的一款高精度、超低功耗I2C接口实时时钟(RTC),专为对功耗、空间和可靠性要求严苛的电子设备设计。依托爱普生在晶振与计时技术领域的长期积累,该产品实现了低功耗与高稳定性的平衡,成为物联网、穿戴设备、工业监测等场景的理想时间管理解决方案。
爱普生作为全球领先的计时元件供应商,其RTC产品以高精度、低功耗、高可靠性为核心竞争力。RX8900CE:UB3定位于小型化、电池供电的嵌入式系统,解决了传统RTC在功耗、封装或温宽上的痛点,尤其适合需要长期续航、紧凑设计的应用场景。
静态电流仅0.7μA(典型值),是同类产品中的领先水平。以常用的CR2032纽扣电池(容量约200mAh)为例,理论续航可达约32年(200mAh ÷ 0.7μA = 285714小时 ≈ 32.6年),无需频繁更换电池,大幅降低设备维护成本。
采用I2C串行接口,支持100kHz/400kHz通信速率,兼容主流嵌入式系统的I2C总线,便于与MCU快速集成。地址可通过硬件引脚配置(部分型号支持),避免地址冲突。
封装规格为10-SMD(无引线表面贴装),尺寸约2.0mm × 2.5mm × 0.8mm,体积紧凑,适合穿戴设备、物联网节点等对PCB空间要求严格的场景,可显著缩小产品尺寸。
RX8900CE:UB3的特性使其适配多类电子设备:
RX8900CE:UB3是一款平衡低功耗、高集成度与可靠性的实时时钟产品,凭借爱普生的技术优势,解决了嵌入式系统中时间管理的核心痛点。无论是需要长期续航的IoT节点,还是紧凑设计的穿戴设备,该产品均能提供稳定、高效的计时解决方案,是工程师设计低功耗嵌入式产品的优选RTC之一。

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.
