PCF8523TS/1,118 产品概述
一、产品简介
PCF8523TS/1,118 是恩智浦（NXP）推出的一款超低功耗实时时钟芯片（RTC），采用14引脚TSSOP封装（0.173" / 4.40 mm 宽）。器件通过标准 I²C 双线串口与主控通信，工作电压范围宽（1.6V ~ 5.5V），内置晶振并带有闹钟输出，可在电池备用时维持时间计数。工作温度范围为 -40℃ 至 +85℃，静态电流典型值仅 150 nA，适合电池供电和低功耗应用。
二、主要规格
- 接口类型：I²C（2 线串口）
- 工作电压：1.6 V ~ 5.5 V
- 晶振：内置
- 闹钟输出：有（可用于唤醒 MCU 或触发外部事件）
- 工作温度：-40℃ ~ +85℃
- 静态电流（Iq）：约 150 nA
- 封装：TSSOP-14（0.173" / 4.40 mm 宽）
- 品牌：NXP（恩智浦）
三、核心特点
- 极低待机电流，延长电池寿命，适合长期时间保持应用。
- 宽电压输入，能够在多种供电方案（单节锂电池、两节电池、外部供电）下工作。
- 内置晶振，简化外部器件需求与 PCB 布局（仍需按照布局建议处理地线与旁路）。
- 可编程闹钟/中断输出，方便实现定时唤醒、闹钟或事件触发功能。
- 标准 I²C 接口，兼容主流微控制器，寄存器访问与配置灵活。
四、典型应用
- 便携式与可穿戴设备的实时时钟与日历功能
- 工业控制设备与数据采集仪器的时间戳与定时唤醒
- 物联网终端、智能传感器节点（长寿命电池）
- POS 机、考勤机、楼宇控制与家电产品中的时间管理
- 数据记录器与事件记录系统
五、设计与使用建议
- 电源旁路：在 VDD 处放置足够的去耦电容，降低供电噪声对计时精度的影响。
- I²C 总线：根据系统电压选择合适的上拉电阻，避免总线泄漏增加功耗。
- 电池备用：设计电池反向隔离或自动切换方案，确保主电源断开时 RTC 继续计时。
- 布局：RTC 周围保持低噪声环境，注意晶振相关走线与地平面完整性以保证时钟稳定性。
- 校准与测试：针对温度漂移进行校准或软件补偿，并在整机温度范围内验证计时误差。
PCF8523TS/1,118 以其低功耗、宽电压与集成化设计，为各种需要长期时间保持与定时唤醒的系统提供可靠且易于集成的方案。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
