SP3243EUEY-L/TR是MAXLINEAR(迈凌) 推出的工业级多通道RS-232收发器,属于高集成度串行通信接口器件。该型号针对多串口通信场景优化,具备3个驱动器(Driver)和5个接收器(Receiver)的通道配置,采用TSSOP-28封装,适用于对空间、可靠性和宽温适应性有要求的嵌入式系统及工业设备。
支持3驱动器+5接收器(3/5配置),可实现3个双向RS-232通信通道(每个通道1发1收),剩余2个接收器可用于单向数据接收,满足多设备并行通信需求(如同时连接传感器、打印机、HMI等外设)。
最大数据速率为1Mbps,覆盖RS-232协议的典型通信速率范围(如9600bps、115200bps、230400bps等),可满足大部分低速串行通信场景的实时性要求。
工作电压范围为3V~5.5V,兼容主流嵌入式系统的供电电压(如3.3V ARM MCU、5V legacy单片机),无需额外电平转换电路,降低系统设计复杂度。
具备**±15kV人体模型(HBM)** 静电防护能力,符合IEC 61000-4-2标准,可有效抵御工业现场、终端设备使用过程中的静电冲击,减少器件损坏风险。
工作温度范围为**-40℃~+85℃**,属于工业级温度等级,可稳定运行于户外、工厂车间等恶劣环境(如低温严寒、高温湿热场景),无需降额使用。
内置电荷泵电路,无需外接高压电容或外部电源(传统RS-232需±12V电源),仅需单电源即可生成RS-232所需的电平,大幅简化外围电路设计,降低BOM成本。
内置电荷泵消除了对±12V高压电源和外接电容的依赖,外围仅需少量滤波电容即可工作,缩小PCB面积,适合紧凑型设备(如手持终端、小型工业控制器)。
3V~5.5V电压范围兼容新旧系统,无需在3.3V与5V系统间增加电平转换芯片,提升系统集成度,减少故障点。
±15kV ESD防护可有效避免生产、运输、使用过程中的静电损坏;工业级宽温范围确保极端环境下的稳定通信,降低售后维护成本。
3/5通道配置可同时支持3个双向串口和2个单向接收通道,满足工业控制、商业终端等场景的多外设连接需求(如PLC需连接多个传感器、HMI、编程接口)。
SP3243EUEY-L/TR采用TSSOP-28封装(薄型小尺寸,引脚间距0.65mm),适合高密度PCB布局,可有效节省设备内部空间。其集成电荷泵、宽电压兼容、工业级宽温及高ESD防护等特性,使其成为多串口通信场景下的高性价比选择,尤其适用于对可靠性和环境适应性要求较高的工业与商业应用。

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.
