USB2640-HZH-02 - 2-Port USB 2.0 Hub Controller | Microchip
MPN: USB2640-HZH-02 ✓ Hoạt độngUSB2640-HZH-02 Tóm tắt
A USB hub controller is an interface IC that manages a USB host connection and distributes that connection across multiple downstream ports. The USB2640 extends this basic hub role by integrating a flash media card reader and writer. The combination can reduce the number of separate USB interface components required in a system, while providing a dedicated path between the USB host and supported flash media.
Key device attributes include support for Hi-Speed USB 2.0 operation, two downstream hub ports, integrated multi-format flash media control, a 48-pin 7 x 7 mm QFN package, and a lead-free RoHS-compliant ordering code. The HZH package designation identifies the 48-pin QFN configuration, while the -02 suffix identifies the specific internal ROM firmware revision within the USB2640 ordering family.
The USB2640 architecture is intended to combine USB expansion and flash media connectivity in a single controller. This integration is especially useful in compact systems where component count, board area, and power efficiency are important. A system designer still must validate the exact flash formats, electrical limits, clock requirements, signal-routing rules, and USB host compatibility for the intended product configuration before releasing a production design.
Typical uses include USB flash-card readers, multifunction peripherals, set-top and media appliances, desktop and notebook accessories, industrial data-transfer equipment, and embedded systems that need both USB hub expansion and removable flash storage. The 7 x 7 mm QFN package also requires careful exposed-pad layout and manufacturing control to achieve reliable electrical and thermal performance.
For implementation, begin with the manufacturer’s USB2640 reference schematic and pin-description table, then reproduce its recommended crystal, capacitor, USB routing, and exposed-pad arrangements. Do not infer pin functions from the package drawing alone. Confirm the required flash-media formats, firmware revision behavior, host-controller requirements, and all operating limits for USB2640-HZH-02 in the latest production documentation.
This page combines the manufacturer’s product description, exact package information, firmware ordering details, cross-reference findings, and practical implementation guidance. It also distinguishes true drop-in alternatives from functional equivalents that require design verification, helping engineers evaluate replacement options without overlooking firmware, media-format, or pin-compatibility constraints.

Ứng dụng tiêu biểu
USB2640-HZH-02 phù hợp cho 6 Áp dụngs: Compact USB Flash-Card Reader, Multifunction USB Peripheral, Industrial USB Data-Transfer Equipment, Desktop and Notebook Accessory Hub, Embedded Flash-Storage Gateway, USB Media Hub and Card Reader.
Compact USB Flash-Card Reader
The USB2640-HZH-02 fits a compact flash-card reader because it combines a 2-port Hi-Speed USB 2.0 hub controller with a multi-format flash media reader/writer in one 48-pin QFN device. The integrated architecture can reduce the component count and board area needed for removable-storage front ends. Place the controller according to the manufacturer reference design, route each USB differential pair as controlled-impedance traces, and confirm that the required card formats match the -02 firmware revision. Validate host compatibility and connector protection before production release.

Multifunction USB Peripheral
A multifunction peripheral can use the USB2640-HZH-02 to combine a two-port USB expansion function with flash-media connectivity. The 7 x 7 mm QFN package is suitable for space-constrained desktop, notebook, and docking accessories, while the integrated flash interface can simplify an internal storage path. The design must account for USB enumeration, the behavior of the -02 firmware revision, bus-power requirements, and media-format support. Use the manufacturer’s reference schematic and verify all exposed-pad and assembly requirements during PCB review.
Được đề xuất
Industrial USB Data-Transfer Equipment
The USB2640-HZH-02 can support industrial data-transfer equipment that needs one upstream USB 2.0 connection, two downstream ports, and removable flash-media access. Its integrated hub-and-media architecture reduces board complexity compared with separating those functions into multiple interface devices. For industrial deployment, verify the exact operating-temperature requirements, supported media formats, host behavior, power-loss tolerance, and connector protection. Maintain controlled USB trace geometry and follow the manufacturer’s recommended grounding and exposed-pad layout to improve signal and thermal performance.
Được đề xuất
Desktop and Notebook Accessory Hub
The USB2640-HZH-02 is suited to a desktop or notebook accessory that expands a single USB host port while also supporting flash-card access. Its two downstream USB 2.0 ports provide basic expansion, and the integrated media controller can serve removable-storage workflows. Designers should verify whether downstream devices may be hot-plugged, how bus power is budgeted, and whether the selected USB connector and protection network satisfy host requirements. The -02 firmware ordering code must also be checked against the desired media-format support.
Được đề xuất
Embedded Flash-Storage Gateway
An embedded storage gateway can use the USB2640-HZH-02 where a host computer accesses removable flash media while the product also offers two USB downstream ports for peripherals. The single-chip hub and media-controller combination helps limit board area in embedded enclosures. Firmware integration must account for the internal ROM revision identified by -02, supported card types, enumeration behavior, and media insertion or removal events. Before hardware release, reproduce the manufacturer clock, decoupling, USB-routing, and exposed-pad arrangements and test the complete system with the intended host platforms.
Được đề xuất
USB Media Hub and Card Reader
The USB2640-HZH-02 is directly aligned with products that need to act as both a USB 2.0 hub and a flash-card reader. A single upstream connection can feed two downstream ports while the flash-media interface handles supported removable storage. The primary engineering trade-off is firmware and media-format dependence: the exact -02 revision must satisfy the product requirements before layout is frozen. Use short, impedance-controlled USB routes, provide the manufacturer-recommended clocking and bypass network, and verify connector, power, and ESD requirements.

Ghi chú thiết kế
Start the layout from Microchip’s USB2640 reference schematic and land pattern rather than a generic 48-QFN footprint. Route each USB differential pair as a short, continuous pair with symmetric geometry and a controlled impedance target. Keep the controller, crystal circuitry, and bypass components close to their associated pins, and avoid placing disruptive digital or switching-regulator paths between the USB transceiver and its connector.
The 48-pin QFN uses a compact 7 x 7 mm land pattern and an exposed pad that must be connected according to the manufacturer’s instructions. Use the recommended via pattern, solder-mask definition, and paste stencil so the thermal pad assembles without voiding or bridging. Confirm PCB copper area and thermal-via geometry against the package drawing before releasing artwork for fabrication.
Do not substitute USB2640I-HZH-02, USB2640I-HZH-02-TR, or USB2641-HZH-02 solely because the order codes look similar. Check the I designation, the -TR suffix, firmware revision, supported media formats, USB host requirements, and every assigned pin. A 48-QFN outline alone does not prove electrical or functional interchangeability, particularly when internal ROM behavior is part of the ordering code.
Apply the manufacturer’s recommended input, output, and bypass-capacitor network directly at the associated device pins. Keep the USB VBUS and internal supply paths sized for the required hub and media-controller load, and review inrush behavior when devices are hot-plugged. The available product information does not state the operating-voltage or current limits, so those values must be taken from the production datasheet before component selection.
