USB2512B/M2 - 2-Port USB 2.0 Hub Controller | Microchip
MPN: USB2512B/M2 ✗ Cuối đờiUSB2512B/M2 Tóm tắt
A USB hub controller is an interface IC that sits between a USB host and one or more USB peripherals. The USB2512B/M2 manages USB traffic, provides downstream-port connectivity, and supports USB 2.0-compatible device integration. Its two-port structure is useful where a host interface needs to connect multiple peripherals without redesigning the host system.
The controller is positioned for USB 2.0 Hi-Speed hub designs and is described by Microchip as low-power and cost-effective. The USB2512B family provides configurable behavior for OEM embedded products. The USB2512B/M2 ordering code is associated with the 36-SQFN package, and distributor results identify the part as a 2-port USB 2.0 Hi-Speed hub controller.
Typical applications include USB hubs in mobile accessories, consumer electronics, docking systems, portable equipment, and embedded USB peripherals. The two downstream ports can simplify connection of peripherals such as keyboards, storage devices, input controllers, or other USB-compatible accessories when the system power and enclosure allow it.
The key design consideration is that USB hub implementation involves more than placing the controller on a PCB. Power-supply design, downstream-port overcurrent protection, USB signal routing, connector selection, firmware configuration, and compliance testing must be developed together. Review the manufacturer datasheet and evaluation-board documentation before finalizing a production layout.
This page summarizes the verified manufacturer and distributor information, identifies the known application context, and separates confirmed data from specifications that still require confirmation in the datasheet or design documentation.

Ứng dụng tiêu biểu
USB2512B/M2 phù hợp cho 6 Áp dụngs: Mobile USB Accessory Hub, Consumer Electronics USB Expansion, Portable Docking System, USB Storage and Input Hub, Embedded USB Peripheral, Battery-Charging USB Accessory.
Mobile USB Accessory Hub
The USB2512B/M2 fits a mobile accessory hub that adds two downstream USB connections to an embedded host. Its USB 2.0 Hi-Speed interface and low-power controller positioning are appropriate for accessories where a compact 36-SQFN implementation is useful. The two downstream ports can serve input, storage, or other compatible peripherals. Product validation must confirm host-driver behavior, connector wiring, power budgeting, and the required USB Battery Charging Specification Revision 1.1 behavior.
Được đề xuất
Consumer Electronics USB Expansion
USB2512B/M2 can provide a compact two-port expansion point in consumer electronics that already has a USB host interface. The controller’s two downstream ports reduce the need for separate hub functions while retaining USB 2.0 Hi-Speed device connectivity. Designers should reserve space for the 36-SQFN exposed-pad footprint, implement USB differential routing, and verify downstream-port current limiting and power-switch requirements.
Được đề xuất
Portable Docking System
A portable dock can use USB2512B/M2 when it needs two downstream USB 2.0 Hi-Speed ports in a limited board area. The MultiTRAK architecture is useful when downstream devices may be connected and disconnected dynamically, because each downstream port has its own transaction translator. Final design work must verify cable length, ESD protection, connector launch geometry, power-source behavior, and operating-temperature requirements.
Được đề xuất
USB Storage and Input Hub
The two downstream ports of USB2512B/M2 can support a mixed USB accessory environment such as storage plus keyboard, mouse, or input-controller connections. The hub role keeps the upstream host interface separate from the downstream device ports while allowing the system to manage multiple USB connections. Designers should account for enumerator support, device-class compatibility, bus-power limits, inrush behavior, and protection requirements at each connector.
Được đề xuất
Embedded USB Peripheral
USB2512B/M2 is suitable for an embedded peripheral enclosure that needs to expose multiple USB connections to a host. Its 36-SQFN package supports compact surface-mount construction, while the low-power description supports portable and embedded equipment. The implementation must include correct USB trace geometry, reference-clock and power design, downstream-port protection, and validation against the intended host operating system.
Được đề xuất
Battery-Charging USB Accessory
The USB2512B family evaluation-board information states that each downstream port can support battery charging according to the USB Battery Charging Specification Revision 1.1. USB2512B/M2 can therefore be evaluated in an accessory architecture where downstream port charging behavior is required. Designers should verify the exact controller configuration, power-source advertisement, charging limits, connector standards, and system-level safety requirements in the manufacturer documentation.

Ghi chú thiết kế
Use the manufacturer 36-SQFN land pattern and maintain the exposed-pad connection recommended in the datasheet. USB differential pairs should be routed as controlled-impedance, length-matched nets with continuous reference planes, short return paths, and protection devices placed where they will not interrupt signal integrity. Confirm the exact pin names and exposed-pad connection from the official package drawing.
Design the hub power path for both downstream ports rather than sizing it from the nominal operating condition alone. Check controller supply voltage, startup current, downstream-device inrush, connector current limits, and thermal rise in the power switches or protection devices. The supplied web data does not provide the complete electrical limits, so validate them against the manufacturer datasheet before release.
Do not assume that another USB251x hub ordering code is a drop-in replacement merely because the family name is similar. Confirm package dimensions, pin names, exposed-pad requirements, port count, clock requirements, configuration options, and USB host compatibility. The verified alternatives are family candidates, but complete pin compatibility is not established for every candidate in the supplied data.
Thông tin tuân thủ
The verified results identify USB 2.0 compliance and mention USB Battery Charging Specification Revision 1.1 for downstream-port support on the USB2512B evaluation board. RoHS, REACH, lead-free, halogen-free, conflict-minerals, and AEC-Q100 status were not confirmed in the supplied data.
