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.

VQFP32 QFN32 Internal Power Supply ESD I/O Reset Level Reset Input The Port pins are driven to their reset conditions when a voltage lower than VIL is applied, whether or not the oscillator is running. RST 16 16 VCC I/0 This pin has an internal 10K pull-up resistor which allows the device to be reset by connecting a capacitor between this pin and VSS. Asserting RST when the chip is in Idle mode or Power-Down mode returns the chip to normal operation. The output is active for at least 12 oscillator periods when an internal reset occurs. For Serial reader: Connect this pin to GND. For USB reader: D+ 29 29 DVCC I/O USB Positive Data Upstream Port This pin requires an external serial resistor of 27 (AT8xC122) or 33 (AT83C5123) and a 1.5 K pull-up to VREF for full speed configuration. For Serial reader: Connect this pin to GND. For USB reader: D28 28 DVCC I/O USB Negative Data Upstream Port This pin requires an external serial resistor of 27 (AT8xC122) or 33 (AT83C5123) For Serial reader: Leave this pin unconnected.
