USB2514BT/M2 产品概述

一、简介

USB2514BT/M2 是 MICROCHIP(美国微芯)推出的一款 USB 2.0 集线器控制器,支持 Low Speed、Full Speed 和 High Speed 三种传输速率,符合 USB2.0 规范的高速度 480 Mbps 传输能力。器件工作电压为 3.3V,工作温度范围宽(-40℃ 至 +85℃),适合工业级和消费类场景的可靠性要求。封装为 QFN-36-EP(6×6 mm),引脚密度适中,利于 PCB 布局与热管理。

二、主要特性

  • 支持 Low/Full/High Speed USB 2.0,最高 480 Mbps(High Speed);
  • 4 个下游端口(通道数:4),便于扩展外设接口;
  • 工作电压:3.3V,符合常见 3.3V 系统供电;
  • 工作温度:-40℃ ~ +85℃,满足工业级应用温度要求;
  • 提供 I2C / SMBus 串行接口,用于连接外部 EEPROM 或进行系统管理与配置;
  • QFN-36-EP(6×6)封装,便于小型化设计与散热。

三、技术要点与应用建议

  • 电源与去耦:3.3V 电源侧应做好去耦,靠近器件布置稳定的 0.1µF 与 1µF 电容,保证瞬态响应与 EMI 控制;
  • USB 线路保护:在上下游的 D+/D- 差分线路上考虑合适的阻抗匹配、共模扼流圈与 ESD 保护器件,保护器件和整个系统的可靠性;
  • I2C/SMBus 接口:若需保存设备描述符或配置参数,可通过外接 EEPROM 在 I2C/SMBus 上实现产品 ID、序列号等信息存储与读取;
  • 热与机械:QFN-36-EP 的 exposed pad 需焊盘良好接地,有利散热与地平面完整性;PCB 多层接地利于信号完整性。

四、典型应用场景

  • 笔记本、平板、迷你主机等扩展 USB 端口;
  • 工业控制与测试设备中对多路 USB 外设的连接与管理;
  • POS 机、医疗设备等需在受控温度与可靠性环境下扩展 USB 口的终端。

五、兼容性与合规

USB2514BT/M2 与主流操作系统和 USB 主控制器兼容,能在标准 USB 拓扑下作为下游端口扩展器使用。具体电源管理、端口控制等功能以 MICROCHIP 官方数据手册和应用说明为准,建议在设计初期参考厂商参考设计与评估板以加速开发验证。

六、总结

USB2514BT/M2 以其四端口、USB2.0 全速/高速支持、工业级温度范围及 I2C/SMBus 配置接口,为对体积、成本和可靠性有较高要求的 USB 扩展应用提供了稳健的解决方案。实际设计中应结合制造商数据手册做详细的电源、信号与 PCB 布局验证,以确保系统长期稳定运行。

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
