The GL3224E-ONY03 is a USB 3.1 Gen 1 to SD Card Reader Controller IC manufactured by Genesys Logic. This chip is responsible for bridging the connection between a USB host (like a computer) and an SD card, allowing the host to read and write data to the SD card. USB 3.1 Gen 1 (formerly USB 3.0) offers high-speed data transfer rates, making it suitable for transferring large files to and from SD cards quickly.

Applications

• USB Card Readers
• Embedded systems requiring SD card access
• Laptop and desktop computers
• Digital cameras
• Other devices needing SD card connectivity via USB

Features

• USB 3.1 Gen 1 (USB 3.0) compliant
• Supports SD/SDHC/SDXC memory cards
• High-speed data transfer rates
• Compliant with USB Mass Storage Class specification
• Supports multiple LUNs (Logical Unit Numbers)
• Low power consumption

Benefits

• Enables fast and efficient data transfer between SD cards and USB hosts
• Provides a reliable and standardized interface for SD card access
• Reduces data transfer times, improving user experience
• Compatible with a wide range of SD card formats
• Allows multiple SD cards to be accessed simultaneously (if the design supports it)

The GL3224E-ONY03 is typically implemented in a small form factor and is often found in external USB card readers. It handles the complex communication protocols between the USB host and the SD card, simplifying the design of SD card readers. The specific package type and power consumption details can be found in the Genesys Logic datasheet. The Ony03 likely refers to a specific revision or production lot of the IC. This allows SD cards to be used as a portable storage media on devices supporting USB.
