SP232EEN 产品概述

一、产品简介

SP232EEN 是 UMW(友台半导体)推出的一款双驱动器/双接收器(2Tx/2Rx)RS‑232 收发器,封装为 SOP‑16,工作电压范围为 4.5V ~ 5.5V,内置电荷泵,可在单一 5V 供电下产生符合 RS‑232 要求的正负电压,工作温度范围 -40℃ ~ +85℃,静态电流典型值约 10mA,数据速率最高可达 120kbps,适用于常见的串口通信接口电平转换需求。

二、主要特性

  • 供电电压:4.5V ~ 5.5V,专为 5V 系统设计
  • 通道数:2 路驱动器、2 路接收器,满足双通道串口或调制解调器接口需求
  • 内置电荷泵:免外部高压电源,简化系统设计
  • 数据速率:上限 120kbps,适合多数串口通信和控制信号
  • 工作温度:工业级 -40℃ ~ +85℃
  • 封装:SOP‑16,便于手工焊接和自动贴片生产
  • 静态电流:约 10mA(无负载),低功耗特性有利于整体能耗控制

三、电气参数与性能亮点

SP232EEN 在单 5V 电源下通过内部电荷泵生成正负电压,输出能驱动符合 RS‑232 规范的信号电平(具体输出幅值与外部电荷泵电容值及负载相关,详见数据手册)。静态电流 10mA 表明待机与非传输时功耗较低;120kbps 的数据速率足以覆盖大多数工业控制、打印机、POS 等设备的串口通信需求。

四、管脚封装与布局建议

  • 封装:SOP‑16,常见 PCB 布局与焊接工艺兼容。
  • 电荷泵电容:通常需外接电荷泵电容(常见为四只电容,典型值 1µF),建议靠近芯片放置以保证电压稳定。
  • 去耦电容:VCC 侧建议并联 0.1µF 陶瓷去耦,贴近 VCC 与 GND 引脚。
  • 布局:高速路径尽量缩短,接地平面完整以降低噪声与辐射;对外串口引脚增加 ESD 防护可提高抗干扰能力。

五、典型应用场景

  • 工业控制设备串口(PLC、人机界面)
  • 嵌入式系统与单片机 UART 电平转换
  • POS、条码扫描器、打印机等外设接口
  • 需要在 5V 供电下实现 RS‑232 通信的通用场合

六、设计注意事项

  • 若系统需更高数据速率或更低功耗,应评估其他高性能器件;120kbps 为器件可靠传输上限。
  • 请依据具体应用选择并验证电荷泵电容的容量与类型,低 ESR 陶瓷电容通常能取得更好性能。
  • 关注器件热耗及 PCB 散热,长时间高频通信情况下芯片温升需在规格范围内。
  • 外接电缆与长线环境下建议增加抗静电与浪涌保护措施,避免损坏收发器。

七、包装与采购信息

SP232EEN 由 UMW(友台半导体)生产,常见封装为 SOP‑16。具体订购型号、最小起订量、交期与价格请联系供应商或查询官方资料以获取最新信息与数据手册,以便在设计中准确参考各项电气参数与典型应用电路。

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
