SP3238EEY-L/TR 产品概述

一、产品简介

SP3238EEY-L/TR 是 MAXLINEAR(迈凌)推出的一款工业级 RS‑232 全功能收发器。该器件在单芯片内集成了 5 路驱动器和 3 路接收器,内置电荷泵,可直接从单一 3.0V 至 5.5V 电源产生 RS‑232 所需电平,适用于多串口或多通道异步串行通信场合。

二、主要规格

  • 工作温度:-40℃ 至 +85℃,满足工业温度等级要求。
  • 工作电压:3.0V ~ 5.5V,可在 3.3V 与 5V 系统中直接使用。
  • 数据速率:最高可达 250 kbps,适配常见串口通信速率。
  • 驱动器/接收器:5 个驱动器、3 个接收器(全功能收发器配置)。
  • 有无电荷泵:有(集成电荷泵,用于产生 ±V 电压)。
  • 静态电流(静态电流消耗):典型值 1 mA(低功耗特性)。
  • 静电保护:针对外部接口提供 ±15 kV 静电防护能力。
  • 封装:28‑TSSOP(紧凑表贴封装,便于多通道集成设计)。

三、功能亮点

  1. 单电源工作且内建电荷泵,消除对外部双电源的需求,简化电源设计。
  2. 低静态电流(约 1 mA),在休眠或空闲时有助于整机节能。
  3. 支持 250 kbps 的数据速率,满足多数工业和嵌入式串口应用的数据传输要求。
  4. ±15 kV 的静电防护增强了系统可靠性,适合恶劣电磁环境或频繁插拔场景。
  5. 28‑TSSOP 封装在 PCB 布局中能实现高密度接口集成,便于多端口设计。

四、典型应用场景

  • 工业控制器与 PLC 的多串口扩展与连接。
  • POS 机、条码仪、票务设备等需要多路 RS‑232 接口的终端。
  • 仪器仪表、数据采集与通信网关。
  • 嵌入式设备中作为 TTL/CMOS 与 RS‑232 电平之间的电平转换器。
  • 网络设备、路由器或串口服务器中用于多串口转发。

五、设计与使用建议

  • 推荐在 RS‑232 信号线处配合合适的防浪涌和滤波措施以提高抗干扰能力。
  • 在对短暂不工作或待机要求较高的系统,注意利用器件低静态电流特性以降低总功耗。
  • PCB 布局时应将模拟电荷泵电容靠近相应引脚布置,确保电荷泵稳定工作并满足 RS‑232 输出幅度要求。
  • 考虑到工业应用的长期可靠性,布线与接地应遵循良好 EMC 实践以配合器件的 ESD 能力。

六、封装与订购信息

该型号采用 28‑TSSOP 封装(带托盘/带卷带规格可选),标准型号为 SP3238EEY‑L/TR,适合自动化贴片生产与批量采购。详细引脚分配和封装尺寸请参照厂商原理图和封装资料以完成 PCB 设计。

七、总结

SP3238EEY‑L/TR 面向需要多通道 RS‑232 接口、单电源供电、低功耗与高可靠性的工业与嵌入式系统。凭借 5 驱动 / 3 接收 的配置、集成电荷泵、3.0–5.5V 宽电压支持以及 ±15 kV 的静电防护,它是实现多串口通信的稳健选择。在设计时结合合理的电源与 PCB 布局策略,可显著提升系统的稳定性与抗干扰能力。若需完整技术参数、引脚图或典型应用电路,请参考 MAXLINEAR 官方数据手册。

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
