USB2228-NE-05 - USB 2.0 Flash Media Controller | SMSC
MPN: USB2228-NE-05 ✓ AktifUSB2228-NE-05 Ringkasan
A USB flash-media controller is an interface IC within the broader USB interface-controller category and the semiconductor hierarchy. It translates host-side USB commands and signals into media-card operations, while also managing the electrical interface between the host and the flash card. The USB2228 generation supports the xD-Picture Card format for licensees of that format, according to the Microchip product page.
Verified information identifies the USB2228-NE-05 as a fourth-generation USB 2.0 flash media controller with integrated card-power FETs. The controller is designed for systems requiring a dedicated USB-to-flash-card interface rather than a general-purpose USB controller. Its 128-pin VTQFP package provides the connections required for host, media, power-management, and associated control functions, although individual pin assignments were not available in the supplied source data.
The product's architecture places the USB host interface, flash-media interface, and card-power control in one integrated component. This integration can simplify board routing and reduce the component count in USB card-reader or portable-media equipment. The manufacturer product page describes support for a single-card interface and xD-Picture Card support, while the datasheet-directory result describes the part as a fourth-generation USB 2.0 flash media controller with integrated card-power FETs.
Typical applications include USB card readers, digital cameras, portable media equipment, and embedded systems that transfer files between a USB host and flash media. The controller is particularly relevant where a USB 2.0 host must communicate with removable flash media using a dedicated, integrated interface. Compared with a software-based or discrete card interface, this controller centralizes protocol handling and card-power control in one package.
Designers should verify the complete pinout, clock requirements, card-support matrix, power sequencing, and PCB layout constraints against the manufacturer datasheet before releasing a PCB. The supplied search results establish the device family, USB 2.0 interface, package size, 128-pin count, card format support, lifecycle status, and basic compliance indication, but they do not provide a complete pin table or confirmed production pricing.
This page consolidates the available manufacturer, distributor, and lifecycle information for USB2228-NE-05, identifies the limits of the supplied data, and provides comparison and design context for engineers evaluating this fourth-generation USB 2.0 flash-card controller.

Aplikasi Biasa
USB2228-NE-05 patut untuk 6 aplikasis: USB Flash Card Reader, Portable Media Player, Digital Camera Media Interface, Industrial USB Media Gateway, Embedded USB Storage Appliance, USB Data Transfer Dock.
USB Flash Card Reader
The USB2228-NE-05 fits a dedicated USB 2.0 card-reader design because it is a fourth-generation flash media controller intended to interface a USB host controller with flash media cards. Its integrated card-power FETs can consolidate card-supply control into the controller, reducing the number of discrete interface functions that a reader must coordinate. The 128-pin VTQFP package also provides the signal and power connectivity expected for a full media interface. Engineers should confirm the exact supported card formats, electrical limits, pin assignments, and connector implementation in the manufacturer datasheet before finalizing the board.
Portable Media Player
A portable media player can use the USB2228-NE-05 to transfer data between flash media and a USB 2.0 host while controlling card power in the same interface IC. This is useful when the product must present removable media to a computer as a USB storage peripheral rather than relying on a general-purpose embedded controller. The verified fourth-generation architecture, USB 2.0 classification, and integrated card-power FETs are directly aligned with that function. Final design work must verify bus-power limits, card-insertion behavior, media compatibility, and enclosure-related connector requirements.
Digital Camera Media Interface
The USB2228-NE-05 is applicable to digital-camera and imaging-product designs that require a dedicated connection between a USB host and removable flash media. The manufacturer product page specifically identifies xD-Picture Card format support for licensees, making the part relevant to products using that format. In such a system, the controller can centralize protocol translation and card-power switching while the host handles file-level transfer. License eligibility, supported card revisions, command behavior, and production firmware requirements should be confirmed with the manufacturer before design freeze.
Industrial USB Media Gateway
An industrial USB media gateway can employ the USB2228-NE-05 when the equipment must expose flash media to an upstream USB host through a dedicated, repeatable interface. Integrating the media controller and card-power FETs can simplify the gateway's power-domain organization and reduce external switching circuitry. The controller is most appropriate where the supported media set and USB 2.0 behavior match the gateway requirement. Because operating-temperature, current-limit, transient, and fault-recovery details were not included in the verified excerpts, the complete datasheet is required for an industrial reliability assessment.
Embedded USB Storage Appliance
The USB2228-NE-05 fits an embedded storage appliance that accepts removable flash media and presents it to a host controller as a USB peripheral. The device's fourth-generation USB 2.0 media-controller role and integrated card-power control make it a focused solution rather than a general USB transceiver. This can reduce the amount of discrete circuitry associated with media detection and power delivery. Designers should verify whether the target operating system expects the same card enumeration, command set, and insertion-removal behavior provided by the USB2228 generation.
USB Data Transfer Dock
A USB data-transfer dock can use the USB2228-NE-05 to provide a controlled interface between its USB host connection and flash media. Integrating card-power FETs with the controller may help designers organize the media power path and limit the number of external control elements. The 128-pin VTQFP package is appropriate for a multilayer board where the host, media, power, and control interfaces can be routed systematically. Connector standards, card insertion detection, power-adapter negotiation, and any host-side device requirements remain application-specific and must be validated independently of the component selection.

Catatan Desain
Treat the 128-pin VTQFP as a high-pin-count mixed-signal interface and route it on a multilayer board. Keep USB data traces short and continuous, provide a solid ground plane, and place required bypass capacitors at the corresponding power pins. The verified material does not include the pin table or recommended capacitor values, so use the manufacturer layout and reference-design guidance rather than assigning nets or capacitors from the package outline alone.
Plan the card-power path around the USB2228-NE-05's integrated card-power FETs, but verify their current ratings, voltage limits, enable polarity, short-circuit behavior, and thermal performance from the complete datasheet. Do not infer safe card-current limits from the USB 2.0 label or from the existence of integrated FETs. Add the required local decoupling and confirm startup and card-insertion behavior across the complete operating range before releasing production hardware.
Do not substitute USB2228-NE-05 merely because another listing uses the USB2228 family name. Confirm the exact orderable suffix, 128-pin package, USB and media pin assignments, supply rails, clocking requirements, supported card formats, and host-driver expectations. No confirmed pin-to-pin substitute was present in the supplied cross-reference data, so any proposed replacement requires schematic-level comparison and hardware validation.
Separate USB routing from sensitive media-card signals, maintain continuous reference planes, and observe the manufacturer's recommended via and fanout geometry beneath the VTQFP. ESD and insertion-life considerations are particularly important in removable-media products because the external connector can expose the board to ESD and mechanical transients. The supplied sources do not specify the controller's external protection network, so select ESD components and placement based on the completed connector and system-level risk assessment.
Maklumat Kesediaan
RoHS compliance is indicated by the verified JLCPCB listing. The datasheet-directory source reports REACH status as vendor undefined, so REACH is treated as unknown. The supplied data does not establish AEC-Q100 qualification, lead-free status, halogen-free status, or conflict-minerals compliance.
