USB2241-AEZG-06 - USB 2.0 Flash Media Controller | Microchip
MPN: USB2241-AEZG-06 ✓ ActiveUSB2241-AEZG-06 Overview
A USB flash media controller is an interface IC that translates commands and data between a USB host and removable flash storage. It belongs to the USB interface controller class, within the broader category of interface ICs and semiconductors. This controller is intended for equipment that reads or manages flash cards through a USB 2.0 host connection, allowing one system architecture to communicate with several widely used flash-media formats.
The USB2241-AEZG-06 is identified as an ultra-fast USB 2.0 controller with multi-format media support. Its principal documented characteristics include USB 2.0 operation, a 3.3 V operating supply, compatibility with SD, MMC, and MS flash media, and a compact 36-VQFN package. The 6 mm by 6 mm package supports compact product designs while exposing the media and USB interface connections required by a multi-format card-reader system.
System integration centers on connecting the USB2241-AEZG-06 between the host-side USB interface and the physical flash-media interface. USB 2.0 provides the host-facing link, while the controller manages the command translation needed to communicate with supported flash cards. This separation allows a host controller to handle USB transactions while the dedicated media controller handles card-format compatibility and media access.
Typical applications include USB card readers, multifunction printers, portable media devices, digital cameras, portable gaming accessories, and embedded equipment that accepts flash media. In these systems, the controller reduces the need for separate card-format handling in the main processor and centralizes access to SD, MMC, and MS devices behind one USB interface IC.
Designers should pay close attention to the 3.3 V supply requirement, the 0°C to 70°C commercial temperature range, and the 36-VQFN land pattern. The exposed pad, power distribution, and high-speed signal layout must follow the manufacturer's package and reference-layout guidance to maintain reliable signal integrity and thermal performance.
This product page combines the manufacturer interface description, package and environmental characteristics, qualified drop-in comparison, commercial sourcing guidance, and practical integration notes. It is intended to help engineers identify whether the USB2241-AEZG-06 matches a USB 2.0 multi-format flash-media design before beginning PCB implementation.

Typical Applications
USB2241-AEZG-06 is suitable for 6 applications: USB 2.0 Multi-Format Card Reader, Multifunction Printer Media Reader, Portable Media Player, Digital Camera Card Interface, Portable Gaming Accessory, Industrial Data Acquisition Peripheral.
USB 2.0 Multi-Format Card Reader
The USB2241-AEZG-06 fits a USB 2.0 card reader that must accept SD, MMC, and MS flash media. The dedicated controller handles the flash-media side of the design while the host-side USB interface connects the reader to a computer or embedded controller. Its 3.3 V operating supply matches common compact USB peripheral architectures, while the 36-pin, 6 mm by 6 mm VQFN package limits board area. The 0°C to 70°C specification suits ordinary indoor commercial equipment. Connector pinouts, media support, and USB routing should follow the manufacturer reference implementation.
Recommended
Multifunction Printer Media Reader
A multifunction printer can use the USB2241-AEZG-06 to add removable-media access alongside printing and scanning functions. USB 2.0 provides a familiar peripheral connection, and support for SD, MMC, and MS flash media broadens compatibility with files used by office users. The controller's 3.3 V operation and compact 6 mm by 6 mm footprint help it fit within a densely populated printer electronics assembly. Its 0°C to 70°C range suits indoor office equipment, although internal printer temperatures must remain within the specified operating limit.
Recommended
Portable Media Player
The USB2241-AEZG-06 is appropriate for portable equipment that transfers files from SD, MMC, or MS flash media through USB 2.0. Concentrating media-format handling in the dedicated controller can simplify the surrounding firmware architecture. Its 36-pin VQFN package is suitable for space-conscious portable products, and the 3.3 V supply aligns with low-voltage embedded systems. The 0°C to 70°C specification covers typical indoor use but does not cover hot vehicle environments or extended temperature ranges. Battery efficiency and warm-start behavior should be evaluated during platform design.
Recommended
Digital Camera Card Interface
In a digital camera or imaging accessory, the USB2241-AEZG-06 can provide a USB 2.0 interface for SD, MMC, and MS flash storage. This arrangement allows recorded media to be accessed by a host computer without placing card-format handling directly in the camera's main processing path. The controller's 3.3 V supply and compact 6 mm by 6 mm VQFN package are well suited to compact electronics. The 0°C to 70°C operating range covers many indoor imaging products, but cameras used in hot vehicles or outdoor installations need environmental margin checked against system requirements.
Recommended
Portable Gaming Accessory
A portable gaming accessory can use the USB2241-AEZG-06 to expose SD, MMC, and MS flash media to a game console or host over USB 2.0. The multi-format support is useful for accessories intended to serve users with different card types. Its small 36-pin VQFN footprint supports compact cable or dock assemblies, and 3.3 V operation fits many embedded peripheral designs. The 0°C to 70°C range covers typical indoor gaming use. Electrical layout should preserve USB signal integrity and provide local decoupling around the controller according to the manufacturer guidance.
Recommended
Industrial Data Acquisition Peripheral
The USB2241-AEZG-06 can serve as a removable-media interface in desktop or wall-mounted data-acquisition equipment that accepts SD, MMC, or MS flash cards. USB 2.0 provides a straightforward connection to a host computer, while dedicated flash-media handling keeps the application processor focused on measurement and control functions. The 3.3 V supply and compact 6 mm by 6 mm package suit peripheral electronics, and the 0°C to 70°C rating covers many indoor industrial environments. For installations with higher ambient temperatures, evaluate the USB2241I-AEZG-06 against its manufacturer grade specification.

Design Notes
Assign the USB, flash-media, power, and ground pins directly from the manufacturer 36-pin VQFN pin-description table. The available product records establish the package and functions but do not reproduce every pin number, so do not infer pad assignments from the package outline. Place input and output decoupling close to the relevant supply pins, preserve the exposed-pad connection specified by the manufacturer, and use the official land pattern rather than a generic 36-QFN footprint.
Treat USB and flash-media connections as high-speed routed interfaces even though the host-facing link is USB 2.0. Use short, continuous reference planes, avoid splits beneath the controller, minimize stub branches, and place any required series termination or impedance-control structures according to the manufacturer application guidance. Keep switching sources and high-current paths away from sensitive media and USB traces to reduce coupled noise and data errors.
Plan the local 3.3 V rail for the controller and its media-interface circuitry with local bypass capacitance positioned close to the supply and ground pins. Confirm the acceptable voltage tolerance, capacitor selection, and exposed-pad connection in the USB224x data brief. Avoid routing noisy media or USB return currents through sensitive power paths, and verify startup behavior across all connected media and host conditions before releasing the layout.
Use the exposed pad and package design as part of the thermal path, following the manufacturer's copper and solder requirements. The specified operating range is 0°C to 70°C, so estimate worst-case enclosure temperature rather than relying only on room ambient. For compact card-reader equipment with limited airflow, conduct thermal testing with the controller, flash connectors, regulators, and USB circuitry operating simultaneously at maximum expected loading.
Compliance Information
The manufacturer part description identifies USB2241-AEZG-06 as RoHS compliant. No verified automotive qualification, REACH declaration, lead-free statement, halogen-free statement, or conflict-minerals declaration was identified for this exact ordering code.
