  • What is embedded software?
    Our software is for those who are going to develop embedded systems with the SD Memory Card. It is provided in the form of "C" language source code that is designed to be ported to any kind of embedded system hardware platform easily by the customers themselves.
  • What is the SD Card Driver?
    The SD Memory Card is a highly-sophisticated memory device about the size of a postage stamp.
  • What is the benefit of using our Driver?
    Since developing driver software is a time consuming job, time-to-market can be considerably shortened by using our products. They are carefully developed specifically for embedded systems, well tested, and you can trust them to complete your project fast and efficiently. Development cost is also much less than developing driver software yourself from scratch.
