USB2250-NU-05 - USB 2.0 Flash Media Controller | Microchip
N.º da peça: USB2250-NU-05 ✓ AtivoUSB2250-NU-05 Visão geral
A USB flash media controller is an interface IC within the broader semiconductor and interface-controller hierarchy. It manages the electrical and protocol-level connection between a USB host controller and removable or embedded flash media. The USB2250 belongs to Microchip's USB225x family, which is positioned around USB 2.0 compliance, interoperability, and rapid transfer of data to widely used flash memory cards.
Key features include USB 2.0 interface operation, FlashMedia controller functionality, a serial interface, and operation from 3.0 V to 3.6 V. The supplied data identifies the controller as an ultra-fast USB 2.0 flash media solution. Its 128-pin VTQFP package provides a large number of mixed-signal, power, ground, and interface connections, allowing support for multiple media interfaces and compact card-reader or embedded-storage designs.
The USB2250-NU-05 combines a USB host-side interface with flash-media-facing controller functions. Available manufacturer information describes the family as providing comprehensive USB 2.0 compliance and interoperability, while distributor records characterize USB2250-NU-05 as a USB 2.0 controller in a 128-VTQFP package. Exact clock, transfer-rate, card-interface, and electrical-limit details were not included in the supplied search records and should therefore be confirmed against the Microchip datasheet before design release.
Typical uses include USB card readers, portable storage systems, digital cameras, personal digital devices, embedded data loggers, and industrial equipment that transfers files through a USB 2.0 host. The device is most appropriate where a dedicated flash-media controller is preferable to implementing the media interface and card-management logic directly in a host controller.
Designers should allocate the complete 128-pin footprint, including exposed-pad and thermal requirements where applicable, and should use the manufacturer reference schematic for exact pin assignments. Because the supplied records use differing maximum supply-current values, 135 mA and 165 mA, power-budget and worst-case startup decisions should use 165 mA until the device-specific datasheet condition is confirmed.
This product page consolidates verified manufacturer and distributor information, package details, commercial availability data, application guidance, and drop-in alternatives into a design-focused reference. It also distinguishes documented values from missing technical parameters rather than estimating them, helping engineers identify what must be checked in the authoritative datasheet.

Aplicações típicas
USB2250-NU-05 é adequado para 6 aplicaçãos: USB Flash Card Reader, Portable Storage Device, Digital Camera and Imaging Appliance, Industrial Data Logger, Embedded USB Storage Adapter, USB Media Port for Set-Top Equipment.
USB Flash Card Reader
The USB2250-NU-05 fits a USB 2.0 flash card reader because it is explicitly identified as a FlashMedia controller with a serial host interface and a 3.0 V to 3.6 V operating range. The device can provide the controller path between a USB host and flash memory media while offloading media-handling logic from the system processor. Its 128-pin VTQFP package provides ample connections for power, ground, USB data, clocking, and media-facing signals. Before layout release, engineers should verify the supported card interfaces, exact pin map, reference clock requirements, and decoupling recommendations in the Microchip USB2250 documentation.
Recomendado
Portable Storage Device
USB2250-NU-05 can serve as the dedicated storage-interface controller in a portable media system that connects to a USB 2.0 host. Its verified 3.0 V to 3.6 V supply range supports a 3.3 V-oriented design, while the FlashMedia-controller architecture allows media access to be separated from the main embedded processor. This division can simplify host-interface software and reduce processor pin requirements. Design validation should include worst-case current analysis using the reported 165 mA figure, examination of suspend and wake behavior, and verification that the required flash-media protocol is supported by the exact USB2250-NU-05 configuration.
Recomendado
Digital Camera and Imaging Appliance
The USB2250-NU-05 is applicable to digital cameras and imaging appliances that store files on flash media and expose a USB 2.0 connection for transfer or configuration. The supplied manufacturer summary specifically identifies modern flash memory cards and high-speed host-to-media transfer as the role of the USB225x family. Using a dedicated FlashMedia controller can isolate card handling from image-processing hardware and provide a defined interface boundary. The integration should be reviewed for supported media standards, transfer-rate expectations, card insertion and removal behavior, and supply sequencing because those detailed limits are not present in the supplied search records.
Recomendado
Industrial Data Logger
USB2250-NU-05 can be evaluated for an industrial data logger that records measurements to flash media and transfers the files to a USB host. Its dedicated USB 2.0 FlashMedia controller role can simplify the boundary between the embedded acquisition processor and removable storage, while the 3.0 V to 3.6 V supply range facilitates integration with 3.3 V power systems. Industrial use requires additional confirmation of the operating-temperature range, endurance-related system design, and lifecycle status because the supplied data does not establish those parameters. A conservative current budget should reserve the higher reported 165 mA supply current until the datasheet condition is clarified.
Recomendado
Embedded USB Storage Adapter
USB2250-NU-05 is suitable for an embedded adapter that bridges an internal system to removable flash media through USB 2.0. The controller's dedicated FlashMedia function allows the main processor to concentrate on its primary control function rather than implementing the complete USB-media protocol. The 128-pin VTQFP package offers a high pin count for the device's combined USB and media-facing connections. Integration must use the official reference design and package drawing for pin assignments, exposed-pad treatment, clock routing, and power distribution, since the verified search records identify the package but do not publish the complete signal-level pinout.
Recomendado
USB Media Port for Set-Top Equipment
USB2250-NU-05 can be considered for set-top or media-access equipment that needs a dedicated USB 2.0 path to flash storage. The 3.0 V to 3.6 V operating range aligns with common 3.3 V system rails, and the USB225x family's stated emphasis on compliance and interoperability supports use in host-connected storage products. Engineering should verify the exact USB host requirements, media standards, transfer performance, and clock configuration against the manufacturer datasheet. Layout planning should also preserve routing flexibility for USB data and media signals across the 128-pin VTQFP footprint rather than treating it as a low-pin-count USB peripheral.

Notas de projeto
Budget the USB2250-NU-05 power rail conservatively because the supplied sources disagree between a 135 mA maximum and a 165 mA reported current. Use 165 mA for initial rail sizing until the manufacturer identifies the exact test condition. The controller operates from 3.0 V to 3.6 V, so the system regulator should remain inside that range under tolerance, startup, and load transients. Confirm the authoritative datasheet for absolute maximum voltage, quiescent current, and any clock or media-interface load before release.
Do not assign signals from a generic TQFP-128 library. Although the package is identified as a 14 mm by 14 mm 128-pin VTQFP, the individual USB, clock, power, ground, and flash-media assignments are not present in the verified records. Import the official Microchip package drawing and symbol, then cross-check every pin against the USB2250-NU-05 datasheet. The exposed-pad connection and thermal requirements must also follow the manufacturer land pattern rather than relying solely on the generic package dimensions.
Route USB data and clock signals using the topology and reference design supplied by Microchip. USB 2.0 edge rates can expose board capacitance, stubs, return-path discontinuities, and power-supply noise even when the protocol is described only as high speed. Keep the media-facing and USB-facing groups organized, provide low-impedance ground connections, and place required decoupling at the associated supply pins according to the manufacturer guidance. Exact trace geometry and capacitor values were not available in the supplied records and must not be inferred.
Do not treat USB2251-NU-05, USB2228-NU-11, or USB2250I-NU-06 as automatic substitutions merely because the web records associate them with the same 128-pin VTQFP class. Compare every pin, supported media interface, clock requirement, supply sequence, USB behavior, operating temperature, and package detail. USB2250I-NU-06 is associated with a 70 °C maximum in the supplied comparison record, which is a material limitation for industrial equipment requiring a wider temperature range.
Informações de conformidade
The supplied USB2250I-NU-06 comparison record states RoHS compliant for that related device, but it does not establish the status of USB2250-NU-05. No product-specific REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declaration was provided for the target.
