CM320

The CM320 is another value-added card reader controller solution derived from CM220. It preserves CM220 features:The first one is True "single-chip" card reader solution.The second one is Online updateable architecture.The third one is Card Manager Application software.

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 OEMs and component manufacturers need not be concerned about stock issues relating to outdated firmware.

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.
