4D µDRIVE-uSD-G1 Embedded (DOS) Drive Module

The micro-DRIVE (uDRIVE-uSD-G1) is an extremely compact high performance “Embedded Disk Drive” module that can be easily added to any microcontroller 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 micro-DRIVE integrates the GOLDELOX-DOS chip onto 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 off the shelf removable microSD memory cards of upto 4GB of capacity and above. A handful of straightforward commands provide direct access to the onboard memory card for 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. Applications can range from data logging, 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 may be the ideal solution.
