CM320

CM320: Updateable USB2.0 Card Reader Controller 
- More Features, More Flexibility, Lowest BOM Cost

Overview

The CM320 is another value-added card reader controller solution derived from CM220. It preserves CM220 features: 

l

True ¡°single-chip¡± card reader solution 

l

Online updateable architecture 

l

Card Manager Application software

 

On top of that, CM320 integrate most of external components: 4 MOS(except MD), 2 regulators, 1 Diode and many passive devices to minimize customer BOM cost, let it be the industry highest integration card reader controller solution.

Its unique software structure makes the function easy to configure to meet the customer versatile demand. 

l

Flexible card configuration

l

Customized smart button design

 

True ¡°single-chip¡± card reader solution (Patent Pending)

The CM320¡¯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 OEMs and component manufacturers need not be concerned about stock issues relating to outdated firmware.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 CM320 allows end-users online update their card readers via Window¡¯s ¡°Automatic Update¡± Function.

File-security Function

l

Private-Disk Function

l

On-Line Update Hotkey

l

Multiple Window

The CM320 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.

Flexible Card Configuration

Any combination of Flash cards is possible and can be programmed by HW or SW. Card icons can also be customized as requested.

Smart Button Design

To provide end-user friendly operation interface, just press one button, many things, ex copy file, print file, encrypt/decrypt file,¡¦etc. could be done without the hassle. Middleware program could be provided to configure the button functions in the future.
