Don´t be limited by a memory space!

If you have a micro-controller based application and you face the problem with insufficient memory space, the micro-drive uSD-G1 may be an ideal solution for you.

The micro-DRIVE uSD-G1 is an extremely compact high performance “Embedded Disk Drive” module that can be easily added to anymicro-controller design that requires a DOS-compatible file and data storage system.

Most micro-controllers have small and limited on-chip memory. For those applications that require large volumes of data, the uSD-G1 with the GOLDELOX-DOS chip is a simple solution in a form of a tiny 'drop-in- module'. A simple serial interface is all that is required to take away the burden of low level design that would otherwise be required for the host controller. The micro-DRIVE module utilises common microSD memory cards of up to 2GB of capacity as its medium. A handful of straightforward commands provide direct access to the onboard memory card or storing and retrieving any size or type of data. Access to the card can be at (FAT based) file levels or at raw disk byte levels.

You can use the micro drive uSD-G1 in applications like data logging (GPS, medical, industrial, security), program storage, music files, image and video files or any type of general purpose data storage. So next time your host micro-controller application requires a file/data storage, the micro-DRIVE maybe the ideal solution. Detailed information will provide you the uSD-G1 datasheet.
