Updateable USB2.0 Ca rd Reader Controlle r Date: 8/2/2005 Version: 1.4 - 3 - 1. INTRODUCTION Overview The CM220 is a USB 2.0 High-speed controller IC compatible with the widest possible range of media card types in the market. The CM220 is also updateable in the field via a simple host driver update to enable compatibility with future media card types. The CM220 supports high speed USB 2.0 data transfer to and from media cards, but is fully backwards compatible with system configurations supporting USB 1.1 full and low speed operation. The CM220 supports 12 different flash media ca rd, 6 mini-size flas h media cards and 6 read-only-type flash card specifications, enabl ing the development of 24-in-1 media card reader devices. The driver software, install ed on the host PC, is updateable via Microsoft’s Windows Update, which allows easy future proofing of the card reader solution. True “single-chip” card reader solution (Patent Pending) The CM220’s patented architecture enables the widest possible compatibility and in-the-field update capability, without the ne ed for external EEPROM or additional components, reducing parts count and costs. The driver software on the host provides all the required programmability. OEMs and component manufacturers need not be concerned about stock issues relating to outdated firmware. Online updateable architecture (Patent Pending) Due to the rapid change of media card specific ations and the growth in capacities in every format, the future compatibilit y of media card reader solutions is becoming more important. C-Media’s innovative CM220 allows end-users online update their card readers via Window’s “Automatic Update” Function Card Manager Application software (Patent Pending) The CM220 can be optionally supplied with a s pecial purpose applicati on shell: the C-Media Card Manager. The C-Media Card Manager prov ides an easy-to-use file management and security function for all media cards.
