Артикул: USB2250-NU-06 ✓ АктивенUSB2250-NU-06 Обзор
A USB flash media card controller is an interface IC within the broader USB controller and storage-interface ecosystem. Its role is to translate commands and data between a USB host and removable flash media while coordinating protocol handling, card interfacing, and host connectivity. The USB2250 belongs to Microchip’s USB225x family, which targets high-speed USB 2.0 flash-media applications requiring a dedicated controller rather than a general-purpose host or peripheral controller.
The verified product data identifies the USB2250-NU-06 as a USB 2.0 interface controller with a maximum host data-transfer rate of 35 Mbit/s. It operates from a 3.3 V supply and supports the Ultra-Fast USB 2.0 flash-media controller role. Its 128-pin VTQFP package provides the interface and support circuitry required for a multi-contact memory-card implementation, although individual pin functions were not included in the supplied excerpts.
The 35 Mbit/s interface rate corresponds to full-speed USB 2.0 operation and is substantially faster than a low-speed USB connection. This makes the controller relevant to products that need a dedicated bridge between a USB host and flash media, including card readers, portable storage equipment, industrial data-collection equipment, and embedded storage systems. The controlled operating supply of 3.3 V also supports integration into modern embedded systems that operate from a 3.3 V power domain.
The package is the principal implementation constraint for engineers evaluating this controller. A 128-pin VTQFP with a 14 mm by 14 mm body and 0.40 mm pitch requires a multilayer PCB and fine-pitch assembly capability. The larger lead count and exposed routing demands are considerably more substantial than those of a compact USB interface controller, but they provide the connections needed for a full flash-media controller implementation.
When designing a PCB around the USB2250-NU-06, verify the exact pin configuration, recommended power and decoupling networks, clock requirements, media-card interface details, and layout guidance in the manufacturer datasheet before release. Because the supplied web excerpts do not provide a verified pin table, stack-up recommendation, impedance value, or thermal-resistance figure, those details should not be inferred from the package alone.
This product page consolidates verified distributor and manufacturer information, distinguishes same-family alternatives, and adds practical selection and PCB-design guidance. It also highlights where engineering teams must consult the complete USB2250/USB2251 datasheet for pin-level, electrical, and layout requirements that cannot be substantiated by the supplied search records.

Типичное применение
USB2250-NU-06 подходит для 6 применениеs: USB Flash Card Reader, Portable Flash Storage, Industrial Data Collection, Embedded USB Storage Gateway, Test and Measurement Instrument, Secure Data Transfer Appliance.
USB Flash Card Reader
The USB2250-NU-06 fits a dedicated USB 2.0 flash-card reader because it combines a 35 Mbit/s host interface with 3.3 V operation in a 128-pin VTQFP implementation. The controller can sit between the USB host and supported flash media, reducing the need for a separate general-purpose controller when the product is designed around the USB2250 family. Its 35 Mbit/s full-speed host rate provides more bandwidth than low-speed USB while keeping the implementation within USB 2.0. The principal engineering tradeoff is PCB complexity: 128 pins at 0.40 mm pitch require careful fanout, adequate copper, and controlled USB routing. Supported card formats, media voltages, and firmware behavior must be verified from the complete manufacturer documentation before release.
Рекомендуется
Portable Flash Storage
USB2250-NU-06 is appropriate for portable storage equipment that must expose flash media through USB 2.0. Its 35 Mbit/s maximum host data-transfer rate supports the USB 2.0 full-speed class, while the 3.3 V supply aligns with compact embedded systems using modern 3.3 V logic. The controller can manage the flash-media side of the product when the mechanical enclosure and target storage format are already supported. Designers should account for the 128-pin VTQFP footprint, 14 mm by 14 mm body, and 0.40 mm pitch when defining a compact board. Bus-power limits, media insertion detection, thermal behavior, and card-format support require verification against the exact USB2250 variant and its approved reference implementation.
Рекомендуется
Industrial Data Collection
The USB2250-NU-06 can be used in industrial data-collection equipment that records information to flash media and later exposes that storage through a USB host. Its dedicated USB 2.0 flash-media role separates storage handling from the product’s primary control task, and the 35 Mbit/s interface rate provides a defined full-speed transfer ceiling. The 3.3 V operating supply also supports integration with embedded processor and logic systems. Before using the standard -06 ordering code in an industrial environment, confirm its operating-temperature range, availability, media endurance expectations, and any qualification requirements. The 128-pin package also demands a multilayer PCB process and careful assembly planning, so prototype assembly should confirm pin 1 orientation and package drawings before release.
Рекомендуется
Embedded USB Storage Gateway
USB2250-NU-06 is relevant to embedded storage gateways that bridge a USB host and removable or embedded flash media. Its USB 2.0 interface operates at up to 35 Mbit/s and uses a 3.3 V supply, allowing the storage path to coexist with a compact embedded control platform. A gateway based on this controller can simplify media-format handling compared with implementing the complete USB storage protocol in the host processor, although firmware and media support still require careful validation. Layout planning must reserve space for the 128-pin, 14 mm-square VTQFP and the associated support network. Controlled-impedance USB routing, media-side signal integrity, bypass placement, and grounding should follow the manufacturer’s USB2250/USB2251 layout guidance to prevent intermittent enumeration or data-transfer errors.
Рекомендуется
Test and Measurement Instrument
USB2250-NU-06 can support test and measurement instruments that store captured data, firmware images, or test results on flash media while retaining a USB host connection. The 35 Mbit/s USB 2.0 rate is suitable for full-speed data transfer, and the dedicated media-controller architecture allows the instrument’s main processor to concentrate on measurement control. The 3.3 V supply supports integration with mixed-signal embedded hardware, while the 128-pin VTQFP demands a sufficiently dense board layout. Engineers should evaluate the supported media set, sustained-transfer behavior, power-budget effect of card access, and operator-facing media-removal workflow. Because detailed timing, current, and pin-level values were absent from the supplied excerpts, schematic and layout decisions should be based only on the current Microchip USB2250 family documentation.
Рекомендуется
Secure Data Transfer Appliance
USB2250-NU-06 can be integrated into a secure data-transfer appliance that uses flash media as a removable or local storage tier and exposes the device through USB. Its dedicated USB 2.0 flash-media controller function operates at up to 35 Mbit/s and from a 3.3 V supply, providing a defined baseline for data movement between a host and media. Security-focused designs must still handle key storage, authenticated media, access control, and safe removal outside this controller. The 128-pin, 0.40 mm-pitch package makes high-quality PCB assembly and adequate decoupling essential. Before release, validate enumeration across target hosts, transfer integrity, card-format behavior, thermal performance, and all security requirements. The verified records do not establish media encryption or secure-boot capabilities, so neither should be inferred from the USB2250 name.

Заметки по проектированию
Design the board for a 128-pin, 0.40 mm-pitch VTQFP rather than treating this as a compact USB peripheral. Use the manufacturer land pattern and package drawing to establish pad geometry, solder-mask clearance, and paste volume. Plan a multilayer stack-up with short escape routes from the fine-pitch device; fanout congestion around all four sides can make single-sided assembly impractical. Confirm pin 1 orientation, component height allowance, and the exact lead-free reflow profile before releasing the PCB footprint.
Keep the USB host interface routed as a controlled-impedance differential pair on a continuous reference plane, and avoid adding test pads, sharp jogs, or plane splits that impair impedance continuity. Keep media-side high-speed or sensitive traces away from USB and clock routing where practical. The supplied excerpts do not provide the manufacturer’s characteristic-impedance target, trace geometry, or media-interface timing, so the final USB and flash-media routing must follow the current USB2250/USB2251 layout and reference-design guidance rather than generic values.
Build the 3.3 V supply network around the manufacturer’s recommended bypass and support components, placing each capacitor at the associated device pin with a short current loop. Validate startup, bus-powered current, card-insertion transients, and auxiliary rail sequencing in hardware. Estimated current consumption and capacitor requirements cannot be calculated from the supplied excerpts because no complete DC parameter table was provided. Review the datasheet for quiescent current, operating current, absolute maximum ratings, and required external components before finalizing the power tree.
