N.º de pieza: USB2241I-AEZG-06 ✓ ActivoUSB2241I-AEZG-06 Descripción general
A USB flash media controller is an interface IC that bridges removable flash-card formats with a USB host. It manages command translation, media access, card detection, and data transfer between the host and SD, MMC, or Memory Stick devices. In the product hierarchy, the USB2241 belongs to the USB interface controller family and ultimately falls within the broader semiconductor and embedded-interface categories.
Key characteristics include USB 2.0 full-speed and high-speed support, a maximum stated transfer rate of 35 Mbps, and a 3.3 V operating supply. The multi-format architecture reduces the need for separate host-side controllers when a product must accept more than one removable-media standard. Its surface-mount VFQFN-36 construction also supports compact card readers, portable storage products, kiosks, and embedded systems requiring integrated media-card connectivity.
The controller is positioned as a peripheral media-interface solution rather than a USB host controller. Its internal task is to translate host USB transfers into operations accepted by the supported flash-media devices while handling the associated media-control functions. System designers still need to implement the correct electrical connections, clocking, decoupling, firmware support, and card-socket signal routing described by Microchip Technology in the USB2241 documentation.
Typical uses include USB card readers, industrial data-collection terminals, portable diagnostic equipment, digital photo and music accessories, and embedded appliances that accept SD, MMC, or Memory Stick media. The same physical 36-QFN format is especially useful when an existing design needs to standardize its footprint across multiple flash-card interfaces while preserving a compact board layout.
Design considerations center on following the manufacturer’s pin-description table, assigning the exposed pad to the intended thermal and electrical plane, and placing required power and clock components close to the device. Signal-routing decisions should preserve USB impedance continuity and isolate sensitive analog or radio-frequency sections from switching and connector-related noise. Firmware and host-driver support must also match the selected card formats and operating system.
This page combines the manufacturer’s functional description with distributor package information, application-focused engineering guidance, and a same-footprint comparison against identified USB2241-family options. It also highlights where a board revision or firmware review remains necessary before selecting a replacement, helping engineers separate package similarity from confirmed application-level compatibility.

Aplicaciones típicas
USB2241I-AEZG-06 es adecuado para 6 aplicacións: USB Flash Card Reader, Industrial Data Collection Terminal, Portable Diagnostic Equipment, Kiosk Media Update System, Digital Photo Accessory, Embedded Flash Storage Gateway.
USB Flash Card Reader
The USB2241I-AEZG-06 fits a compact USB card reader that accepts SD, MMC, or MS flash media because the controller specifically mediates communication between a USB host and those flash-card formats. It supports USB full-speed and high-speed operation up to 35 Mbps and operates from 3.3 V, allowing the design to use a conventional USB interface power architecture. Its 36-pin VFQFN package occupies substantially less board area than a large through-hole controller solution. The implementation should use the manufacturer pin table for USB, clock, media-card, power, and exposed-pad connections, then validate the selected card types with the intended host software.
Recomendado
Industrial Data Collection Terminal
The USB2241I-AEZG-06 is appropriate for an industrial data-collection terminal that must import logged files from removable SD, MMC, or MS media. The controller provides a direct USB 2.0 host interface to supported flash cards and supports transfers at up to 35 Mbps, which suits routine configuration, diagnostic, and batch-data exchange. Its 3.3 V supply requirement supports integration into embedded controller platforms, while the compact VFQFN package simplifies dense front-panel designs. Before deployment, verify the device’s operating-temperature rating and compliance documentation, and account for connector insertion, ESD protection, power sequencing, and long-term availability of the selected media format.
Recomendado
Portable Diagnostic Equipment
The USB2241I-AEZG-06 can serve portable diagnostic equipment that receives configuration data, service logs, or test captures through standard flash media. USB 2.0 full-speed and high-speed support offers a practical path to a host connection, and the controller’s 3.3 V operation can fit equipment power trees built around embedded processors. Its 36-pin VFQFN package is advantageous in handheld mechanical layouts where connector placement and board area are constrained. The system designer should keep USB traces impedance-controlled, route card signals according to the manufacturer reference layout, and define safe behavior for inserted, removed, corrupt, or unsupported media in the product firmware.
Recomendado
Kiosk Media Update System
The USB2241I-AEZG-06 fits a kiosk update system that receives signed content or configuration packages from SD, MMC, or MS flash media. By providing a standardized USB 2.0 path between the kiosk controller and removable media, it separates the storage medium from the embedded computing platform. The stated 35 Mbps high-speed rate is suitable for routine content transfer, while the 3.3 V supply and compact 36-pin VFQFN package simplify integration beside the kiosk’s power and I/O circuitry. Firmware should validate media identity, reject malformed files, and enforce atomic updates so a power interruption cannot leave the kiosk in an inconsistent state.
Recomendado
Digital Photo Accessory
The USB2241I-AEZG-06 is suitable for a digital photo or music accessory that imports files from SD, MMC, or Memory Stick media through USB. The device handles the USB-facing side of a removable-media interface, allowing the host to enumerate the supported card type without placing that protocol burden on the accessory’s main application processor. Its 35 Mbps maximum stated transfer rate provides a practical file-transfer path for compressed media collections, and the VFQFN-36 package supports compact enclosures. Layout must separate sensitive analog or image-processing sections from connector and card-socket activity, with suitable ESD protection and grounding implemented at the external connectors.
Recomendado
Embedded Flash Storage Gateway
The USB2241I-AEZG-06 can support an embedded gateway that converts removable flash media into a USB-accessible storage path for another controller or host. Its multi-format capability makes it relevant when a product must accept SD, MMC, and MS media while presenting a common USB interface upstream. The 3.3 V operating voltage simplifies integration with compatible embedded logic, and the compact 36-pin VFQFN package leaves board area for power, protection, and connectors. A production design should verify media-format behavior, hot-plug requirements, maximum supported media capacity, and card-socket signal conditioning using the manufacturer’s device documentation.

Notas de diseño
Use the manufacturer pin-description table to assign all 36 VFQFN leads and the exposed pad. Place required power-decoupling and clock components close to their associated pins, keep USB and flash-media traces short, and provide a continuous ground reference beneath the device. The 6 x 6 mm footprint leaves little room for improvised escape routing, so verify pad geometry and land pattern against the current package drawing before releasing the PCB.
Route high-speed USB and flash-card signals as controlled-impedance interconnects with minimal stubs and appropriately placed series termination where required. Keep the media-card connector, ESD-protection devices, and switching circuitry away from sensitive clock and analog sections. Maintain a direct return path beneath each high-speed pair, and use the exposed pad as part of the intended ground or thermal plane rather than leaving it isolated.
Do not assume that two 36-pin USB2241-family controllers are interchangeable solely because their packages match. Compare exact pin names, power requirements, supported card formats, configuration straps, clocking, and firmware expectations for every candidate. A PCB that was routed for the -06 ordering code should not be converted to the -05 candidate without a documented pin-level comparison and an appropriate board and firmware review.
External card sockets and USB connectors introduce ESD and conducted-noise risks. Place protection close to the connector, provide a low-impedance chassis or signal-ground strategy appropriate to the product, and prevent transient current from entering the controller area. Validate the completed design for USB compliance and media-access reliability under insertion, removal, and ESD-event conditions rather than relying only on schematic inspection.
