XRA1201PIG24TR-F 16位I2C/SMBus接口I/O扩展器产品概述

XRA1201PIG24TR-F是迈凌(MAXLINEAR)推出的16位通用I/O扩展器,专为解决微控制器(MCU)引脚资源不足问题设计,通过I2C/SMBus串行接口实现GPIO的高效扩展,兼具低功耗、宽电压适应性与灵活配置特性,适用于工业控制、消费电子、智能家居等多领域场景。

一、核心功能与定位

作为串行I/O扩展器,XRA1201PIG24TR-F通过标准I2C/SMBus总线与MCU通信,将16个独立I/O引脚映射到串行总线上,无需占用MCU额外GPIO引脚即可实现多路数字输入/输出控制。其内置中断输出功能,可实时通知MCU I/O状态变化,减少MCU轮询频率,提升系统响应效率与功耗表现。

二、关键技术参数详解

  1. 接口与通信
    支持I2C与SMBus双协议,时钟频率最高达400kHz(快速模式),兼容主流MCU的I2C接口,通信速率满足大多数应用需求;
  2. I/O配置
    16位双向I/O,每个引脚可独立配置为输入或输出,输出类型支持开漏与三态门:开漏输出适合线与逻辑(如多设备共享总线),三态输出可避免总线冲突,适配不同负载驱动场景;
  3. 电压与功耗
    工作电压范围1.65V~3.6V,覆盖1.8V、3.3V等常见MCU电压,无需电平转换;静态电流仅1μA,低功耗特性适合电池供电的便携式设备;
  4. 输出电平与可靠性
    输出高电平(VOH)典型值2.6V,输出低电平(VOL)最大400mV,满足TTL/CMOS逻辑电平要求;工作温度范围-40℃~+85℃(工业级),适应恶劣环境;
  5. 封装
    采用24-TSSOP封装,体积紧凑(5.0mm×4.4mm),适合PCB空间紧张的高密度设计。

三、灵活的I/O应用特性

  1. 独立配置与中断触发
    每个I/O引脚可单独设置为输入/输出,输入时支持电平变化检测(上升沿/下降沿),状态变化可触发中断输出,MCU无需持续轮询I/O状态,大幅降低系统功耗;
  2. 输出驱动兼容性
    开漏输出可外接上拉电阻,适配5V逻辑电平(需注意上拉电压),三态输出则支持高阻态,避免总线冲突,适合多设备共享I/O总线的场景;
  3. 地址灵活性
    支持多设备级联(通过硬件地址引脚设置不同I2C地址),最多可扩展多组16位I/O,满足复杂系统的多路控制需求。

四、典型应用场景

  1. 工业控制
    用于PLC、工业传感器接口扩展,实现多路数字量输入(如温度传感器、限位开关)与输出(如继电器、指示灯控制),中断输出快速响应现场状态变化;
  2. 智能家居
    智能家居中控系统的I/O扩展,控制灯光、窗帘、安防传感器等16路设备,低功耗特性适配电池供电的无线模块;
  3. 消费电子
    便携式医疗设备(如血糖仪、血压计)的按键与显示接口扩展,解决MCU引脚不足问题,宽电压范围兼容设备内不同芯片电压;
  4. 汽车电子
    车载辅助系统(如倒车雷达、氛围灯)的I/O扩展,工业级温区适应车载环境的温度变化。

五、产品优势总结

  • 引脚扩展高效:通过I2C/SMBus仅需2根线即可扩展16个I/O,节省MCU引脚资源;
  • 低功耗与宽电压:静态1μA功耗+1.65~3.6V电压范围,适配电池与不同MCU平台;
  • 灵活配置与中断:独立I/O配置+中断输出,提升系统响应效率;
  • 工业级可靠性:-40~85℃温区+24-TSSOP封装,适应恶劣环境与高密度设计。

XRA1201PIG24TR-F凭借上述特性,成为中小系统I/O扩展的优选方案,可有效简化电路设计、降低成本并提升系统性能。

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
