SP3232EEY-MS 是 MSKSEMI(美森科)提供的一款双通道收发器,专为 MCU/微控制器与串行 RS-232 设备之间的电平转换而设计。器件集成电荷泵,可在单一 3.0V 到 5.5V 的电源下工作,支持最高约 120 Kbps 的数据速率,工作温度覆盖工业级 -40℃ 到 +85℃。器件提供 2 个驱动器与 2 个接收器,包装形式为 TSSOP-16,并具备高达 ±15 kV 的静电放电(ESD)保护能力。
SP3232EEY-MS 将 MCU 的 TTL/CMOS 逻辑电平转换为符合 RS-232 要求的差分电压,并将来自 RS-232 总线的电平转换回 MCU 可识别的逻辑电平。内部电荷泵利用外接电容(常见配置为四个电荷泵电容)在单电源条件下生成所需的正、负电压,从而无需额外的 ± 电源即可驱动 RS-232 线路。
SP3232EEY-MS 以其内置电荷泵、宽电源电压范围、低静态电流以及工业级工作温度和高 ESD 抗扰能力,为需要可靠 RS-232 通信接口的嵌入式与工业系统提供了简单且成本效益高的解决方案。其 TSSOP-16 封装利于高密度 PCB 设计,适合多种串口拓展与系统集成场景。

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.
