USB2230-NU-02 - USB 2.0 Flash Media & IrDA Controller | Microchip
Артикул: USB2230-NU-02 ✗ Снят с производстваUSB2230-NU-02 Обзор
A USB host interface controller is a semiconductor that bridges a USB port and one or more peripheral interfaces. In the broader hierarchy, USB2230-NU-02 belongs to interface controllers, interface ICs, and integrated circuits. Its two principal interface functions are USB 2.0 host connectivity and IrDA infrared data communication, allowing one controller to serve systems that need both wired USB and short-range optical data paths.
The main verified feature set includes USB 2.0 operation, parallel and serial interface support, IrDA controller functionality, flash-media controller functionality, a 3.0 V to 3.6 V operating supply range, 30 mA supply current, and integrated card power FETs. The 128-TQFP package provides 128 external connection points in a 14 x 14 mm body, making it appropriate for embedded equipment with sufficient board area for a high-pin-count surface-mount controller.
The USB2230 is identified by Microchip as a fifth-generation USB 2.0 composite device. It interfaces a single USB host port with mainstream flash-card media interfaces and also includes an IrDA controller. Its integrated card power FETs can simplify power-delivery arrangements for supported media interfaces, while its composite architecture can reduce the need for separate controllers when a product must support USB media access and infrared communication.
Typical applications include multifunction printers, media readers, docking stations, portable data-transfer equipment, embedded USB hosts, and industrial or communications equipment that combines removable flash storage with IrDA. In these systems, USB 2.0 provides the connection to a host computer, while the flash-media interface handles card access and the IrDA block provides infrared communication. The integrated card power FETs are especially relevant where the attached media interface requires controlled card-power delivery.
Designers should verify the complete pin configuration, signal mapping, clocking requirements, media-interface implementation, and card-power topology against the manufacturer datasheet before layout release. Because this controller uses a 128-TQFP package and connects external flash media through dedicated pins, routing, return paths, and connector placement can materially affect implementation complexity. The verified data also identifies the part as obsolete, so new production designs should confirm availability and lifecycle strategy before committing to the MPN.
This product page consolidates verified distributor pricing, package information, interface capabilities, source links, and same-family drop-in candidates into an engineering-oriented reference. It also distinguishes confirmed specifications from fields that still require datasheet confirmation, making the information more useful for lifecycle review, footprint assessment, and replacement planning.

Типичное применение
USB2230-NU-02 подходит для 6 применениеs: Multifunction USB Printers, Flash-Media Readers and Docking Stations, Industrial Data-Transfer Equipment, Portable IrDA and USB Adapters, Embedded USB Host Control Systems, Communications and Network Peripherals.
Multifunction USB Printers
The USB2230-NU-02 fits a multifunction printer that must accept print jobs through a USB 2.0 host connection while also supporting direct flash-media access or IrDA communication. Its verified single-host-port architecture, 3.0 V to 3.6 V supply range, and 30 mA supply current suit embedded USB host designs. Integrated card power FETs can simplify media-card power control when the attached interface matches the manufacturer's application circuit. Layout must preserve the 128-TQFP signal assignments and provide the required routing for USB, flash-media, IrDA, power, and ground pins.

Flash-Media Readers and Docking Stations
USB2230-NU-02 is appropriate for a flash-media reader or docking station that exposes removable storage through a USB 2.0 host interface. The controller's verified flash-media support and integrated card power FETs reduce the need for separate power-control circuitry where the manufacturer's recommended topology is followed. Its 3.0 V to 3.6 V operating range integrates directly with a compatible 3.3 V power architecture. The 128-TQFP package requires careful high-pin-count layout, particularly around media data, card-power, ground-return, and USB differential-signal routing.
Рекомендуется
Industrial Data-Transfer Equipment
The USB2230-NU-02 can serve industrial data-transfer equipment that combines USB storage access with an IrDA communication path. Its verified USB 2.0 controller, IrDA functionality, and parallel/serial interface support allow a compact embedded design to manage two communication routes. The listed 30 mA supply current provides a reference for the controller's 3.0 V to 3.6 V supply design, while integrated card power FETs support compatible flash-media implementations. Engineers must still verify environmental ratings, timing margins, isolation requirements, and lifecycle availability for the exact obsolete ordering code.
Рекомендуется
Portable IrDA and USB Adapters
USB2230-NU-02 is suitable for a portable adapter that presents USB media connectivity alongside IrDA infrared communication. The verified IrDA controller and USB 2.0 interface support a composite product without separate controllers for those two functions. Its 3.0 V to 3.6 V supply range can align with portable 3.3 V system rails, although battery regulators must meet startup and load requirements. Because the controller uses a 128-TQFP 14 x 14 mm package, portable-product designers should evaluate board area, connector placement, and thermal performance before selecting it.
Рекомендуется
Embedded USB Host Control Systems
The USB2230-NU-02 can serve as the host-controller element in an embedded system that reads compatible flash media or communicates through IrDA. Microchip identifies it as a fifth-generation USB 2.0 composite device designed around a single USB host port, which gives designers a defined integration target for embedded host products. The verified 3.0 V to 3.6 V supply range and 30 mA current simplify initial power budgeting, while the integrated card power FETs assist compatible media designs. Full qualification requires checking the complete pinout, media timing, firmware support, and card-power limits in the manufacturer datasheet.
Рекомендуется
Communications and Network Peripherals
USB2230-NU-02 is applicable to communications peripherals that need a USB 2.0 host connection, flash-media access, and optional IrDA connectivity in a single controller. Its verified 128-TQFP package and integrated card power FETs can support a feature-rich peripheral while limiting the number of separate interface devices. The 3.3 V-compatible supply range allows integration with standard embedded rails, but USB signal routing, media-card power sequencing, and thermal performance remain important design considerations. Because availability is limited by the obsolete lifecycle status, new communications platforms should evaluate a supported redesign path.

Заметки по проектированию
Reserve the complete 128-TQFP 14 x 14 mm footprint before committing the board, and obtain the official pin map rather than relying on distributor pinout images. Route the USB differential pair as a controlled impedance pair with a continuous reference plane, keep the media-interface and card-power routes away from sensitive USB circuitry, and provide the decoupling network and ground connections specified by the manufacturer reference design.
Design the controller rail for the verified 3.0 V to 3.6 V supply range and budget for the listed 30 mA supply current. Do not equate that figure with complete product consumption because attached flash media, USB loads, IrDA circuitry, regulators, and card power can require additional current. Validate startup, card-power sequencing, connector current limits, and regulator thermal behavior across the complete operating load range.
Do not substitute USB2229 or another USB2230 ordering code solely because the package name matches. Confirm that every required flash-media signal, IrDA function, card-power FET connection, configuration input, supply pin, and ground pin is present and electrically equivalent. The obsolete lifecycle status also makes it important to check firmware support, last-time-buy availability, and whether the selected source provides genuine, traceable stock.
Separate USB, media-data, and card-power paths according to the manufacturer's layout guidance. Keep media-card power routing compact while maintaining adequate copper for transient current, and place input bypass capacitance at the relevant supply pins with a short ground return. Because the complete operating-temperature and thermal-resistance data were not provided, thermal qualification must use the official package information rather than estimates from this listing.
