USB2224-NE-02

Controllers Overview

The SMSC USB2224-NE-02 is a fifth-generation high-speed USB flash media controller featuring integrated card power field-effect transistors (FETs). Designed for embedded USB solutions, this component supports low-speed, full-speed, and high-speed downstream devices. It functions as a bridge between USB host controllers and various flash memory standards, including Secure Digital (SD), MultiMediaCard (MMC), and CompactFlash (CF) interfaces. The device incorporates an integrated IrDA controller to support infrared data association protocols alongside standard block storage operations.

Controllers Feature Summary

• Integrated card power FETs eliminate the need for external power switching components
• Supports multiple flash media formats including SD, MMC, and CompactFlash
• Includes built-in IrDA controller for wireless infrared connectivity
• Fully compliant with USB 2.0 specifications for high-speed data transfer

Controllers Applications

• Embedded USB mass storage devices requiring compact form factors
• Digital cameras and multimedia players utilizing flash memory cards
• Industrial control systems integrating infrared communication capabilities
• Portable electronic devices needing direct USB-to-flash interface solutions

Controllers Procurement Notes

Verify the specific suffix NE-02 against official Microchip or legacy SMSC documentation to confirm package type and temperature range. Ensure compatibility with existing PCB layouts designed for fifth-generation USB controllers. Cross-reference pin assignments with similar models like USB2230 to validate footprint compatibility if substituting within the family.

Controllers Selection Notes

Select this controller when designing systems that require simultaneous support for diverse flash media types and infrared functionality. Consider the integrated power FETs for simplified schematic design and reduced bill of materials. Evaluate system power budgets against the controller's operational requirements and ensure adequate thermal management for the chosen package style.

Controllers Part Context

This component belongs to the SMSC USB22xx series of fifth-generation high-speed USB flash media controllers. These devices are widely used in embedded applications to provide robust connectivity between USB hosts and various non-volatile memory standards. The series emphasizes integration by combining protocol translation, media support, and power management into a single silicon solution.

Controllers Replacement Considerations

Direct drop-in replacements may include other variants from the USB22xx family such as the USB2230, provided pinouts and electrical characteristics match. Verify that alternative parts maintain support for required media types and IrDA features. Consult official datasheets to confirm functional equivalence before implementation.
