Microchip USB2244I-AEZG-06-TR: A High-Performance Flash Media Controller for Modern Embedded Systems

The Microchip USB2244I-AEZG-06-TR is a highly integrated USB 2.0 flash media controller designed to provide a robust and efficient bridge between a host system and various types of flash memory. This system-on-chip (SoC) solution is engineered to deliver superior performance and reliability, making it an ideal choice for a wide range of embedded applications, from industrial computing and set-top boxes to automotive infotainment and digital signage.

At its core, the controller supports high-speed USB 2.0 (480 Mbps) connectivity, ensuring fast data transfer rates that are crucial for handling large multimedia files and application data. Its key strength lies in its extensive native support for popular flash media formats, including SD, SDIO, MMC, and Memory Stick cards. This native support eliminates the need for additional bridge chips, simplifying board design and reducing the overall bill of materials (BOM) and system cost.

A significant feature of the USB2244I is its integrated ARM7TDMI-S microprocessor. This core provides the necessary processing power to manage the complex protocols of the various flash media types and the USB interface, all while running the firmware stored in its on-chip ROM. This integrated design enhances security and reliability while offloading the main host processor, leading to improved overall system performance.

The device is offered in a compact and space-efficient 48-pin QFN (6x6mm) package, making it suitable for space-constrained applications. The -TR suffix indicates it is supplied on a tape and reel, which is essential for high-volume, automated assembly processes. Furthermore, its industrial-grade temperature range ensures stable operation in demanding environments.

ICGOOODFIND: The Microchip USB2244I-AEZG-06-TR stands out as a powerful, all-in-one solution for adding removable flash media storage via USB. Its combination of high-speed performance, broad native flash support, and an integrated processor makes it a versatile and reliable choice for developers seeking to enhance their product's connectivity and functionality.
