CM220 Datasheet | C-Media Electronics

Overview The CM220 is a USB 2.0 High-speed controller IC patible 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 patibility with future media card types. The CM220 supports high speed USB 2.0 data transfer to and from media cards, but is fully backwards patible with system configurations supporting USB 1.1 full and low speed operation. The CM220 supports 12 different flash media card, 6 mini-size flash media cards and 6 read-only-type flash card specifications, enabling the development of 24-in-1 media card reader devices. The driver software, installed 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 patibility and in-the-field update capability, without the need for external EEPROM or additional ponents, reducing parts count and costs. The driver software on the host provides all the required programmability. OEMs and ponent manufacturers need not be concerned about stock issues relating to outdated firmware.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 specifications and the growth in capacities in every format, the future patibility of media card reader solutions is being 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 special purpose...
