A complete document can be found on the Omnikey Web site.http://omnikey.aaitg.com AT83C23OK Description Smart Cards are increasingly being used for Payments, Home-Banking, Access Control, Internet Security, PKItokens, Health Care, Loyalty, etc. The CardMan Smart@Link chip set is a ready to use precertified smart card reader interface, that can be implemented into USB hosts. It facilitates hardware integrators by reducing time-to-market and offers a unique opportunity to quickly and easily include smart card reader functionality in systems like PCs, Notebooks, Keyboards, Smart Card based Dongles, Monitors, Mice, PDAs, Thin Clients, Biometric devices etc. The already existing certifications and compliances guarantee a fast and easy certification process. With its high performance Smart Card Interface CardMan Smart@Link supports smartcard technology of the future. The integration in any USB system can be easily done without any firmware or software (driver) development, simply by embedding the CardMan Smart@Link design and chipset into the target system. The USB CCID support makes this process the easiest ever by connecting host and Smart Card Reader systems without the need of additional drivers. CardMan Smart@Link combines Atmel’s AT83C5123 microcontroller and Omnikey firmware. For detailed information on the Omnikey firmware, please refer to the Omnikey web site: http://omnikey.aaitg.com. In addition to the summary information contained in this document, please refer to the AT83C5123 datasheet for complete product information.
