GM3488ESA是GATEMODE(捷茂微)推出的1发1收全双工接口收发器,核心面向3V-3.6V低压系统的高速数据传输需求,兼容RS-485/RS-422通讯协议,可实现双向同步数据收发。其本质是完成「MCU逻辑电平→差分信号」与「外部差分信号→逻辑电平」的双向转换,保障数据在长距离、抗干扰环境下的可靠传输,广泛适配工业控制、智能家居等场景。
GM3488ESA采用SOP-8贴片封装,体积紧凑(5.2mm×6.0mm×1.6mm),适配主流贴片生产线,便于批量焊接与系统集成。引脚功能清晰:
引脚 功能说明 电平特性 1脚(VCC) 电源输入 3.0V~3.6V 2脚(DI) 数据输入(MCU→收发器) 逻辑电平 3脚(RO) 数据输出(收发器→MCU) 逻辑电平 4脚(GND) 地 - 5脚(DE) 驱动使能 高电平有效(启动发送) 6脚(RE) 接收使能 低电平有效(启动接收) 7脚(A) 差分信号正端 差分电平 8脚(B) 差分信号负端 差分电平其中DE/RE引脚可联动控制收发状态(如DE=0、RE=1时进入低功耗待机),简化电路设计。
适配PLC、DCS等工业控制器的RS-485接口,实现传感器数据采集(温湿度、压力)、执行器控制(电机、阀门)的双向通讯,工业级温区与高ESD防护满足工厂车间的 harsh 环境需求。
作为中控系统与智能设备(灯光、窗帘、安防传感器)的通讯接口,3V-3.6V电压适配智能家居MCU,低功耗特性延长设备待机时间,全双工模式支持实时状态反馈(如窗帘位置同步)。
用于机顶盒、智能电视的外设对接(如红外扩展、串口设备),1Mbps速率满足音视频辅助数据传输,SOP-8封装便于设备小型化设计。
适用于户外环境监测(气象站、土壤传感器)的无线中继节点,低功耗特性降低电池更换频率,差分传输保障100米内数据可靠传输。
GATEMODE(捷茂微)是国内专注于接口芯片、电源管理芯片的研发制造厂商,GM3488ESA依托其成熟的模拟电路设计能力,具备以下核心优势:
GM3488ESA凭借「低压适配、高可靠、低功耗」的特性,成为工业控制、智能家居等领域的高性价比接口方案。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
