CM220
Updateable USB2.0 Card Reader Controller
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 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 compatibility and in-the-field
update capability, without the need 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outdated firmware.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 specifications and the growth in capacities in every
format, the future compatibility 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 special purpose application shell: the C-Media
Card Manager. The C-Media Card Manager provides an easy-to-use file management and
security function for all media cards.
