USB2228AHZS07 USB 2.0 Flash Media Controller | SMSC
Teilenummer: USB2228AHZS07 ✓ AktivUSB2228AHZS07 Übersicht
An application-specific microcontroller is a specialized semiconductor optimized for a defined set of system functions rather than general-purpose software execution. Within the product hierarchy, this device belongs to the microcontroller and embedded-controller class, while its specific application places it in the flash media controller category. This integration can reduce the number of discrete components required between a USB port and a removable flash card.
The fourth-generation controller architecture identifies the USB2228 family as a dedicated USB 2.0 storage solution. USB 2.0 provides a standardized host-to-controller interface, while the integrated card functionality manages communication with supported removable flash media. The part is specifically listed by Rochester Electronics as an application-specific microcontroller from SMSC, and market listings associate the device with a 26-page manufacturer datasheet.
Designing with this controller requires attention to the USB host interface, card electrical requirements, supported media formats, embedded firmware, and the exact package dimensions. Because the device is application-specific, its operational behavior is typically determined by its internal firmware and board configuration rather than by a general-purpose processor application. Designers should preserve the reference network, clocking arrangement, power sequencing, and card-detection implementation used by the manufacturer.
Typical uses include USB flash-card readers, card-reader appliances, portable storage accessories, embedded storage gateways, and host systems that require direct access to removable flash media. In each case, the controller handles the USB-to-card interface while the surrounding circuit supplies regulated power, termination, protection, and the physical media connector.
The principal design trade-off is integration versus upgrade flexibility. A dedicated flash media controller can simplify the USB storage path, but it is less versatile than a general-purpose microcontroller. Validate the supported card types, transfer modes, firmware configuration, package land pattern, and signal-routing requirements before releasing a new PCB layout.
This product record combines the exact USB2228AHZS07 identification, manufacturer description, package-related uncertainty, verified source links, and application-oriented engineering guidance. It also separates confirmed attributes from parameters that require confirmation against the manufacturer datasheet, helping engineers plan sourcing and hardware review without obscuring unresolved design assumptions.

Typische Anwendungen
USB2228AHZS07 ist geeignet für 6 Anwendungs: USB Flash-Card Reader, Portable Storage Accessory, Embedded Media Gateway, Industrial USB Storage Appliance, USB Storage Test Equipment, Secure Document Transfer Device.
USB Flash-Card Reader
USB2228AHZS07 fits a USB flash-card reader because its documented role is a fourth-generation USB 2.0 flash media controller with an integrated card interface. The device can form the central bridge between a USB host and removable flash media, reducing the need for separate USB and card-control logic. The exact implementation must follow the manufacturer reference circuit for power, clocking, termination, card detection, and media-specific connections. Engineers should confirm supported card formats, bus timing, operating limits, and package dimensions before layout release.
Empfohlen
Portable Storage Accessory
A portable storage accessory can use USB2228AHZS07 when the product requires a dedicated USB 2.0 path to removable flash media. The integrated card interface is valuable in space-constrained accessories because it can consolidate functions normally divided among a USB controller, media reader, and supporting logic. Design work should include low-power startup, connector protection, card insertion detection, stable reference rails, and signal routing that preserves USB and card timing. Firmware and supported-media configuration must be verified for the intended product experience.
Empfohlen
Embedded Media Gateway
USB2228AHZS07 is appropriate for an embedded media gateway that accepts flash media through a USB-facing storage path. Its specialized flash media controller architecture can provide a focused interface without requiring a general-purpose processor to manage the USB-to-card transaction layer. The implementation should account for host enumeration behavior, media insertion and removal, power-gating coordination, and fault handling. Before board fabrication, engineers must verify the supported media set, transfer modes, pin assignments, and electrical reference design.
Empfohlen
Industrial USB Storage Appliance
Industrial USB storage appliances can use USB2228AHZS07 when a dedicated USB 2.0 flash-media interface is required inside a larger embedded system. The application-specific controller reduces the firmware burden compared with a general-purpose processor, but it places more importance on following the manufacturer's validated reference design. Designers should evaluate environmental temperature limits, ESD protection, power-loss behavior, connector mechanics, and card endurance requirements. Production release also requires confirmation of package tolerances, lifecycle status, and exact-suffix supply.
Empfohlen
USB Storage Test Equipment
USB2228AHZS07 can support a storage test fixture designed to expose a host to flash media through a dedicated USB media-controller path. Because the part is application-specific, it may simplify a repeatable test interface compared with a software-driven general-purpose USB design. The fixture still requires controlled power rails, reliable card insertion detection, protected connector routing, and a host-side test harness. Confirm the exact supported media, enumeration behavior, transfer limits, and firmware configuration to ensure that measurements reflect the intended device class.
Empfohlen
Secure Document Transfer Device
USB2228AHZS07 may be used in a document-transfer appliance that accepts approved removable flash media and exposes it through USB 2.0. A specialized media controller can provide a predictable hardware boundary between the host and the selected card interface. Security depends on the complete product architecture, including media validation, firmware behavior, connector protection, and host-side policy, rather than on the controller designation alone. Engineering review should verify supported formats, card detection, power sequencing, package layout, and recovery behavior after interrupted transfers.

Designhinweise
Use the manufacturer datasheet's land pattern and reference layout when placing USB2228AHZS07. Keep USB traces short and impedance-controlled, place termination close to the relevant device pins when required, and route card-interface signals away from noisy power-conversion stages. Confirm the exact package, pin count, exposed-pad arrangement, and exposed-pad connection before releasing artwork because those details are not established by the product listing.
Design the supply network around the exact voltage and current limits listed in the manufacturer electrical-characteristics table. Provide local decoupling at each applicable power pin and keep USB and card-interface return currents within a continuous ground path. Check startup, card insertion, and maximum-load behavior with the intended regulator because the dedicated controller architecture does not eliminate the need for correct rail sequencing and transient control.
USB 2.0 edge rates make connector-to-controller routing and return-path continuity critical. Avoid stubs, test pads, and unnecessary vias on high-speed nets, and observe the manufacturer's referenced topology for series elements and routing geometry. For the removable card interface, preserve the recommended connector and signal arrangement because edge-aligned or exposed-card contacts can introduce timing and ESD risks that are separate from USB compliance.
Do not treat every USB controller as an interchangeable flash-card controller. Verify supported media types, card detection polarity, insertion timing, required firmware, supply levels, and package pin assignments against the exact USB2228AHZS07 suffix. A board with an unverified footprint can appear electrically correct while failing at card insertion, removal, or hot-plug events. Use the manufacturer reference schematic and pin table as the release checklist.
Compliance-Informationen
The available product records identify the device as an SMSC application-specific USB flash media controller but do not state its RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status.
