SC16IS740IPW,128 产品概述

一、概述

SC16IS740IPW,128 是恩智浦(NXP)推出的一款高度集成的串口桥接器,提供单通道UART并通过I²C或SPI主接口与主控通信。器件支持高达5 Mbps 的串口速率,内部收发FIFO为64字节,适用于需要将 MCU/SoC 的并行/总线接口扩展为标准串口通信的工业与嵌入式应用。芯片本身为逻辑层UART控制器,可与外部RS‑232或RS‑485收发器配合,实现总线级的物理层转换。

二、主要参数

  • 工作温度:-40℃ ~ +95℃
  • 最大串口速率:5 Mbps
  • FIFO深度:64 Byte(Tx/Rx合计/分别视配置)
  • 主机接口:I²C、SPI
  • 串口通道数:1
  • 工作电压:3.3V / 2.5V(需按型号和系统电源选择)
  • 封装:TSSOP-16
  • 品牌:NXP(恩智浦)

三、关键特性与优势

  • 单通道UART控制,协议兼容标准串口,适配现有串口驱动与固件。
  • 支持I²C与SPI两种主接口,系统设计灵活,可在总线资源受限时通过I²C多点扩展。
  • 内建64B FIFO,有效减轻主控中断负担,提高数据吞吐稳定性,适合高实时或突发数据场景。
  • 支持高达5 Mbps的高速串口通信,满足工业级高速数据链路需求。
  • 工作温度范围宽(-40℃ ~ +95℃),适合工业与车规级外围系统(注意整体系统认证)。

四、典型应用场景

  • 工业控制系统:将MCU通过I²C/SPI扩展为多个串口节点,连接传感器、PLC或诊断终端。
  • 现场总线网关:与RS‑232/RS‑485收发器配合构建多协议网关或串口转以太网/无线模块。
  • 仪器仪表与数据采集:用于长时间稳定采集、高速串口设备的数据中继与缓存。
  • 嵌入式消费与医疗设备:在空间受限的PCB上以TSSOP‑16封装节省空间同时保证性能。

五、设计与使用建议

  • 物理层:芯片仅为逻辑层UART控制器,若需RS‑232/RS‑485通信,请外接相应收发器并做好差分/保护设计(共模扼流、TVS)。
  • 电源与布线:在VCC引脚附近放置低ESR去耦电容(如0.1µF+1µF),并按2.5V或3.3V电源规范布局。若系统有不同IO电平,需使用电平转换器或选择匹配电压版本。
  • 接口选择:I²C模式适合总线扩展与低引脚占用场合,SPI模式在高实时性与更高带宽需求下优先选择。注意SPI时序与片选管理。
  • 中断与FIFO:合理利用中断线与FIFO阈值,减小CPU占用并避免FIFO溢出。对持续高流量场景,评估中断/轮询策略和缓冲区处理。
  • 温度与可靠性:在高温或工业环境上应考虑散热与焊接工艺,保证长期稳定工作。

六、封装与订购信息

SC16IS740IPW,128 为 TSSOP‑16 封装,适合紧凑型PCB布局。购买与选型时请确认电压版本(2.5V/3.3V)、封装与工作温度等级,若需实现RS‑232/RS‑485功能,可同时选配对应的物理层收发器与防护元件。

总结:SC16IS740IPW,128 以其单通道、高速率、双主接口与工业级工作温度优势,适合需要可靠串口桥接、总线扩展与高吞吐的工业及嵌入式设计场景。

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
